11:20-11:35: Query efficient algorithms to find Nash Equilibrium in two player zero sum games, Arnab Maiti

Abstract: Two-player zero-sum games are a widely studied topic with applications ranging from economics and optimization to modern AI. Motivated by recent developments in areas such as dueling bandits and AI alignment, we revisit the classical problem of two-player zero-sum games and ask the following question: Can one find the Nash equilibrium of a two-player zero-sum game without knowing all of its payoffs? We answer this question in the affirmative, presenting simple and elegant algorithms that achieve this.

11:35-11:50: Self-RedTeam: Improving LLM Safety via Adversarial Self-Play, Mickel Liu

Abstract: Conventional LLM safety alignment is a reactive cat-and-mouse game where target models perpetually lag behind new attacks from users. This paper introduces SELF-REDTEAM, an online reinforcement learning framework that forces a single LLM to improve its safety alignment by simultaneously playing both sides of a red-teaming game: attacker and defender. The model co-evolves by generating adversarial prompts to exploit its own vulnerabilities and then learning to safeguard against them, all while the outcome reward adjudicates the game. Both roles leverage hidden Chain-of-Thought (CoT) to develop private strategies that are invisible to the opponent, a mechanism shown to be critical for discovering diverse attacks. This dynamic self-play approach proves highly effective, uncovering significantly more diverse attacks and improving safety robustness by as much as 95% compared to models trained with standard safety procedures.

11:50-12:05: Sample, Don’t Search: Rethinking Test-Time Alignment for Language Models, Gonçalo Faria

Abstract: Increasing test-time computation has emerged as a promising direction for improving language model performance, particularly in scenarios where model finetuning is impractical or impossible due to computational constraints or private model weights. However, existing test-time search methods using a reward model (RM) often degrade in quality as compute scales, due to the over-optimization of what are inherently imperfect reward proxies. We introduce QAlign, a new test-time alignment approach. As we scale test-time compute, QAlign converges to sampling from the optimal aligned distribution for each individual prompt. By adopting recent advances in Markov chain Monte Carlo for text generation, our method enables better-aligned outputs without modifying the underlying model or even requiring logit access. We demonstrate the effectiveness of QAlign on mathematical reasoning benchmarks (GSM8K and GSM-Symbolic) using a task-specific RM, showing consistent improvements over existing test-time compute methods like best-of-n and majority voting. Furthermore, when applied with more realistic RMs trained on the Tulu 3 preference dataset, QAlign outperforms direct preference optimization (DPO), best-of-n, majority voting, and weighted majority voting on a diverse range of datasets (GSM8K, MATH500, IFEval, MMLU-Redux, and TruthfulQA). A practical solution to aligning language models at test time using additional computation without degradation, our approach expands the limits of the capability that can be obtained from off-the-shelf language models without further training.

11:20-11:35: Scaffolding Youths’ Critical Exploration and Evaluation of AI Systems, Jaemarie Solyst

Abstract: With great recent innovation in AI, youth are surrounded by AI systems. Youth use AI for learning, entertainment, social interaction, creativity, and more. However, AI can often have significant limitations and socio-ethical implications worth considering. How can youth be supported in critically exploring and evaluating AI system behavior, especially in the age of generative AI (GenAI)? In this talk, we share findings from a study where we investigated how culturally responsive computing theories and intersectional identities can support Black Muslim teen girls develope critical literacy and creativity with and about GenAI. Specifically, we show how fashion design with GenAI exposes affordances and limitations of current GenAI tools. As the learners used GenAI to create depictions of their fashion collections, they encountered the socio-ethical limitations of AI. Learners used their intersectional identities and funds of knowledge to assess and ideate GenAI behavior. Overall, these hands-on, creativity-based interactions with GenAI and critical discourse supported their development of critical AI literacy.

11:50-12:05: An Approach to Support Teens’ Everyday Ethical Thinking About AI, Rotem Landesman, Ph.D. Candidate, The Information School

Abstract: As teens are increasingly interacting with artificially intelligent (AI) tools and platforms, they are confronted with complex ethical dilemmas in their daily lives. Few pedagogical supports and frameworks exist to guide teens in their thinking about everyday ethics, or the ethical aspects and decisions intermingled in everyday life. Providing young people with the tools to practice and explore their everyday ethical thinking skills is important if they are to develop an understanding of ethical issues from a socio-technical perspective, as well as allowing them to manifest a space for agency in their daily lives as these technologies continue to integrate themselves in their environments.

This talk will cover some of my work exploring one approach to support teens in their everyday ethical reasoning processes about AI technologies. The suggested approach aims to support teens’ everyday ethical thinking by foregrounding (1) fostering a Community of Philosophical Inquiry (CPI) created around a specific real-world use case relevant to teens, and (2) introducing the nuances of ethical thinking by utilizing tools from the field of Philosophy for Children (P4C). I describe some of my work exploring the merits of this approach by working with several groups of teens, collaboratively writing guidelines for using AI tools in their schools.

Additionally, this talk will share preliminary insights from an ongoing project focused on pitching this approach for fostering teens’ everyday ethical thinking to high school educators in a school setting. After seeing initial promising results from working with teens, my ongoing work with educators aims to explore these pedagogical scaffoldings with teachers and collaboratively create tools and thinking practice for them to bring these nuanced ethical conversations into their classrooms.

Topic: Causality, Learning, and Communication in the Brain

Abstract: The Systems Neuroscience and AI Lab (SNAIL) develops and applies machine learning techniques to understand how our brains drive our capacities to sense, feel, think, and act. We design computational models and analytical tools to reverse-engineer neural computation, drawing on large-scale recordings of spiking activity from populations of hundreds or thousands of neurons in the brain. In this talk, I will highlight recent and ongoing SNAIL efforts that view large neural populations as dynamical systems whose structure and activity evolve lawfully over time. I will begin by describing how this perspective has enabled us to efficiently identify causal structure in biological neural networks, which is revealed through neural responses to external perturbations that are algorithmically chosen to be maximally informative. I will then discuss deep learning approaches to dynamical systems modeling that allow us to uncover how neural population activity changes during learning and how multiple brain regions communicate with each other to support distributed computation. Together, these advances are helping to elucidate fundamental principles by which the brain organizes its dynamics to support flexible and intelligent behavior.

1:50-2:05: CellCLIP – Learning Perturbation Effects in Cell Painting via Text-Guided Contrastive Learning, Mingyu Lu

Abstract: High-content screening (HCS) assays based on high-throughput microscopy techniques such as Cell Painting have enabled the interrogation of cells’ morphological responses to perturbations at an unprecedented scale. The collection of such data promises to facilitate a better understanding of the relationships between different perturbations and their effects on cellular state. Towards achieving this goal, recent advances in cross-modal contrastive learning could, in theory, be leveraged to learn a unified latent space that aligns perturbations with their corresponding morphological effects. However, the application of such methods to HCS data is not straightforward due to substantial differences in the semantics of Cell Painting images compared to natural images, and the difficulty of representing different classes of perturbations (e.g., small molecule vs CRISPR gene knockout) in a single latent space. In response to these challenges, here we introduce CellCLIP, a cross-modal contrastive learning framework for HCS data. CellCLIP leverages pre-trained image encoders coupled with a novel channel encoding scheme to better capture relationships between different microscopy channels in image embeddings, along with natural language encoders for representing perturbations. Our framework outperforms current open-source models, demonstrating the best performance in both cross-modal retrieval and biologically meaningful downstream tasks while also achieving significant reductions in computation time.

2:05-2:20: Fast and Slow Population-level Mechanisms of Learning in the Motor Cortex, Jacob Sacks

Abstract: How do neural populations adjust activity during learning to improve behavior? Neural population activity is governed by external inputs and local recurrent dynamics. Thus, modifying inputs and local dynamics constitute two key population-level learning mechanisms. To understand how they work together to modify population activity, we studied the primary motor cortex (M1) of rhesus macaques during brain-computer interface learning experiments. We built recurrent neural network models of M1 that accurately recapitulated before-learning population activity. Then, we asked whether external input changes could sufficiently account for after-learning population activity, or if local changes were required. Within a day, we found learning is primarily input-driven, which is limited in its ability to restructure M1 activity. Between days, while the monkeys are task-disengaged, we found local changes do emerge. Altogether, these results support a two-staged learning process separated by distinct timescales, explaining constraints on rapid learning and how they are overcome over days.

2:20-2:35: Leveraging Molecular Programming for Smart Diagnostics, Zoe Derauf

Abstract: Adherence to antiretroviral therapy (ART) is essential for HIV treatment and prevention, yet current monitoring methods rely on centralized, instrument-intensive assays that are impractical for point-of-care use. We introduce EMERALD–an isothermal diagnostic platform that integrates reverse transcriptase (RT) inhibition with DNA strand displacement (DSD) to quantify intracellular nucleoside reverse transcriptase inhibitors (NRTIs), key pharmacologic markers of adherence. EMERALD employs a staged assay design that captures drug incorporation events, even in the presence of endogenous dNTPs, translating them into programmable fluorescence or colorimetric outputs in under 15 minutes. The system achieves nanomolar sensitivity, tunable dynamic range, and multiplexed detection of multiple NRTIs in a single reaction.

Beyond adherence monitoring, EMERALD serves as a rapid, high-throughput assay for screening new RT inhibitors and can be adapted for non-nucleoside (NNRTI) and nucleotide reverse transcriptase translocation inhibitor (NRTTI) drugs, as well as other RT or polymerase-targeting treatments. EMERALD demonstrates the potential of dynamic DNA nanotechnology to enhance molecular diagnostics, offering a versatile platform for therapeutic drug monitoring and drug development in diverse clinical and research settings.

This session highlights three exciting projects in robotics, including: a new type of suction cup that has the potential to drastically improve the robustness of object handling in warehouse automation, a technique that enables robots to quickly learn new tasks from simple language instructions, and an evaluation framework that provides detailed, meaningful insights into the performance of robot manipulation models.

1:30-1:35: Introduction and Overview, Dieter Fox

1:35-1:55: Smart Suction Cups with Capacitive Tactile Sensing, Alexander Choi

Abstract: In warehouse automation and industrial handling, suction cups are a simple and versatile gripping solution, but they can fail when alignment or contact quality can’t be verified. Vision systems can help, but are frequently occluded by the gripper itself or lack the precision needed for fine alignment. This talk introduces a smart suction cup that uses mutual capacitive sensing to remotely detect deformations in a standard conductive suction cup. By placing multiple electrodes on a sensing board beneath the cup, the system measures changes in mutual capacitance that reveal how the cup bends and contacts a surface. This enables robots to infer contact quality, detect misalignment, and monitor payload dynamics (such as swaying) during motion. Early prototypes show strong signal fidelity and clear sensitivity to contact geometry, suggesting a practical path toward more reliable, self-correcting suction gripping in real-world settings.

1:55-2:15: ReWiND: Language-Guided Rewards Teach Robot Policies without New Demonstrations, Jesse Zhang

Abstract: We present ReWiND, a new framework that allows robots to learn manipulation skills directly from language instructions—without needing separate demonstrations for each task. Traditional robot learning methods depend on human-provided examples or hand-crafted reward functions, which limit scalability. ReWiND instead learns from a small set of initial demonstrations to build two key components: (1) a model that can interpret language commands and evaluate a robot’s progress, and (2) a general-purpose policy that learns from this feedback. When facing new tasks, ReWiND adapts the policy quickly using its learned reward model, needing only minimal additional data. In experiments, ReWiND generalizes to new tasks up to 2.4× better than existing methods and adapts 2–5× faster in both simulation and real-world tests. This brings us closer to robots that can flexibly learn new tasks from simple language instructions.

2:15-2:35: RoboEval: Where Robotic Manipulation Meets Structured and Scalable Evaluation, Helen Wang

Abstract: As robotic systems grow more capable, how we measure their performance becomes increasingly important. Many policies can now complete manipulation tasks successfully, yet they often differ in how smoothly, precisely, or coordinately they move. Capturing these differences requires evaluation methods that look beyond simple task success. In this talk, I will introduce RoboEval, a structured evaluation framework and benchmark for robotic manipulation that integrates principled behavioral and outcome metrics. RoboEval includes eight bimanual tasks with systematically controlled variations, more than three thousand expert demonstrations, and a modular simulation platform for reproducible experimentation. Each task is instrumented with standardized metrics that quantify fluency, precision, and coordination, along with outcome measures that trace stagewise progress and reveal characteristic failure modes. Through extensive experiments with state-of-the-art visuomotor policies, we demonstrate how RoboEval enables richer, more interpretable comparisons across models and tasks. By combining structure, scalability, and behavioral insight, RoboEval takes a step toward more meaningful evaluation of robotic manipulation.

Abstract: We introduce proactive hearing assistants that automatically identify and separate the wearer’s conversation partners, without requiring explicit prompts. Our system operates on egocentric binaural audio and uses the wearer’s self-speech as an anchor, leveraging turn-taking behavior and dialogue dynamics to infer conversational partners and suppress others. To enable real-time, on-device operation, we propose a dual-model architecture: a lightweight streaming model runs every 12.5 ms for low-latency extraction of the conversation partners, while a slower model runs less frequently to capture longer-range conversational dynamics. Results on real-world 2- and 3-speaker conversation test sets, collected with binaural egocentric hardware from 11 participants totaling 6.8 hours, show generalization in identifying and isolating conversational partners in multi-conversation settings. Our work marks a step toward hearing assistants that adapt proactively to conversational dynamics and engagement.

Biography: I’m passionate about audio and speech technologies, building models that help computers truly understand sound and interact with humans naturally.

Abstract: Fetal heart rate (FHR) monitoring is critical for prenatal care, yet current methods rely on expensive, specialized equipment and trained personnel, limiting accessibility in low-resource and at-home settings. We present DopFone, a novel approach leveraging the built-in speaker and microphone of commodity smartphones to non-invasively estimate FHR via Doppler-based audio sensing. Our system emits an 18 kHz low-pitched ultrasound from the smartphone speaker and analyzes reflected signals recorded by the microphone to detect abdominal surface vibrations caused by fetal cardiac activity. Combining Doppler sensing with an AdaBoost regression model (validated via Leave-One-Out Cross-Validation on 23 pregnant participants), DopFone achieved a mean absolute error of 2.1±1.3 BPM compared to a reference-standard medical Doppler device. The 95% limits of agreement (±4.90 BPM) fall well within the clinically acceptable threshold of ±8 BPM. The system demonstrated robustness across gestational ages (19-39 weeks), maternal BMI (23-67 kg/m2), and variations in phone positioning. Our results establish that smartphones can deliver clinically reliable FHR estimation without external hardware, gel, or probes, bridging the gap between clinical monitoring and accessible at-home assessment.

3:15-3:30: Engagements with Generative AI and Personal Health Informatics: Opportunities for Planning, Tracking, Reflecting, and Acting around Personal Health Data, Shaan Chopra

Abstract: Personal informatics processes require navigating distinct challenges across stages of tracking, but the range of data, goals, expertise, and context that individuals bring to self-tracking often presents barriers that undermine those processes. We investigate the potential of Generative AI (GAI) to support people across stages of pursuing self-tracking for health. We conducted interview and observation sessions with 19 participants from the United States who self-track for health, examining how they interact with GAI around their personal health data. Participants formulated and refined queries, reflected on recommendations, and abandoned queries that did not meet their needs and health goals. They further identified opportunities for GAI support across stages of self-tracking, including in deciding what data to track and how, in defining and modifying tracking plans, and in interpreting data-driven insights. We discuss GAI opportunities in accounting for a range of health goals, in providing support for self-tracking processes across planning, reflection, and action, and in consideration of limitations of embedding GAI in health self-tracking tools.

2:45-3:00: Living Sustainability: In-Context Interactive Environmental Impact Communication, Alexander Le Metzger

Abstract: Climate change demands urgent action, yet understanding the environmental impact (EI) of everyday objects and activities remains challenging for the general public. While Life Cycle Assessment (LCA) offers a comprehensive framework for EI analysis, its traditional implementation requires extensive domain expertise, structured input data, and significant time investment, creating barriers for non-experts seeking real-time sustainability insights. Here we present the first autonomous sustainability assessment tool that bridges this gap by transforming unstructured natural language descriptions into in-context, interactive EI visualizations. Our approach combines language modeling and AI agents, and achieves >97% accuracy in transforming natural language into a data abstraction designed for simplified LCA modeling. The system employs a non-parametric datastore to integrate proprietary LCA databases while maintaining data source attribution and allowing personalized source management. We demonstrate through case studies that our system achieves results within 11% of traditional full LCA, while accelerating from hours of expert time to real-time. We conducted a formative elicitation study (N=6) to inform the design objectives of such EI communication augmentation tools. We implemented and deployed the tool as a Chromium browser extension and further evaluated it through a user study (N=12). This work represents a significant step toward democratizing access to environmental impact information for the general public with zero LCA expertise.

3:00-3:15: The Problem of the Alaskan Snow Crab: Building Species-agnostic Tools for Behavior Analysis, Moses Lurbur

Abstract: The understanding of animal behavior plays a crucial role in the development of therapeutic treatments, mitigating the impact of human intervention in the natural environment, and improving agricultural efficiency. Currently, our ability to automatically quantify, detect, and analyze animal behavior from videos is constrained by brittle, class- and domain-specific computer vision models.

Motivated by a unique environmental challenge – saving the Alaskan snow crab fishery from collapse – we are building tools for automated, species-agnostic behavior quantification and analysis. Using the latest foundation models for object detection, segmentation, pixel tracking, and image encoding, we are developing methods to detect, quantify, and classify animal behavior across domains, from fisheries science to medicine, with minimal manual annotation. 

Building useful scientific tools starts with a deep understanding of the applicable domains, current limitations, scientific questions, available data, and desired impact. In our work, we have taken a bottom-up approach to tool development, closely collaborating with industry and research partners to motivate our work, build custom datasets, and inform the development of our tools.

Abstract: At the heart of conservation are the field staff who study and monitor ecosystems. Recent advances in AI models raise the question of whether LLM assistants could improve the experience of data collection for these staff. However, on-device AI deployment for conservation field work poses significant challenges and is understudied. To address this gap, we conducted semi-structured interviews, surveys, and participant observation with partner conservancies in the Pacific Northwest and Namibia, identifying elements central to field-deployable conservation technology while also better understanding the field work context. To critically analyze how on-device AI would affect field work, we employ speculative methods through the frame of an on-device transcription-language model pipeline, which we built atop of EarthRanger, a widely-used, open-source conservation platform. Our findings suggest that although on-device LLMs hold some promise for field work, the infrastructure required by current on-device models clashes with the reality of resource-limited conservation settings.

2:45-3:00: Collaborative and Proactive Conversational Agents for Open-Ended Dialogue, Vidya Srinivas

Abstract: As large language models (LLMs) become increasingly embedded in interactive applications, evaluation has largely centered on task performance, typically measured via benchmark datasets, expert annotations, or automated model-based raters. While valuable, these approaches assess conversations from a detached, third-party perspective, often overlooking a critical dimension of real-world deployment: how interaction style shapes user engagement and the quality of contextual input. Without meaningful engagement, users are unlikely to remain with a conversational system long enough for it to have a real impact. In this work, we argue that effective LLM-driven dialogue systems must do more than generate accurate or fluent responses—they must also elicit richer user input through natural, collaborative conversational strategies. To support this, we introduce an explicit control-flow framework in which LLMs think before they speak, crafting responses in a latency-aware manner. We design and evaluate five distinct dialogue styles informed by expert design principles, and assess them using a multi-dimensional framework that includes expert judgments, automated metrics, and first-person user feedback. Our findings show that collaborative conversational agents not only increase user engagement but also help gather higher-quality contextual input, ultimately improving both user satisfaction and task outcomes.

4:25-4:40: Foundation Models for Wearable Health, Girish Narayanswamy

Abstract: Wearable sensors have become ubiquitous thanks to a variety of health tracking features. The resulting continuous and longitudinal measurements from everyday life generate large volumes of data; however, making sense of these observations for scientific and actionable insights is non-trivial. Inspired by the empirical success of generative modeling, where large neural networks learn powerful representations from vast amounts of text, image, video, or audio data, we investigate the development of sensor foundation models for wearable health data. Using a dataset of up to 40 million hours of in-situ pulse, electrodermal activity, accelerometer, skin temperature, and altimeter per-minute sensor data from over 165,000 people, we create LSM (Large Sensor Model), a multimodal foundation model built on the largest wearable-signals dataset with the most extensive range of sensor modalities to date. This work, a collaboration between University of Washington and Google researchers establishes the utility of such generalist models for wearable health and explores its applications from activity recognition, and hypertension risk, to insulin resistance, and health forecasting.

3:55-4:07: Video Tokenization via Panoptic Sub Object Trajectories, Chenhao Zheng

Abstract: Current approaches tokenize videos using space-time patches, leading to excessive tokens and computational inefficiencies. The best token reduction strategies degrade performance and barely reduce the number of tokens when the camera moves. We introduce grounded video tokenization, a paradigm that organizes tokens based on panoptic sub-object trajectories rather than fixed patches. Our method aligns with fundamental perceptual principles, ensuring that tokenization reflects scene complexity rather than video duration. We propose TrajViT, a video encoder that extracts object trajectories and converts them into semantically meaningful tokens, significantly reducing redundancy while maintaining temporal coherence. Trained with contrastive learning, TrajViT significantly outperforms space-time ViT (ViT3D) across multiple video understanding benchmarks, e.g., TrajViT outperforms ViT3D by a large margin of 6% top-5 recall in average at video-text retrieval task with 10x token deduction. We also show TrajViT as a stronger model than ViT3D for being the video encoder for modern VideoLLM, obtaining an average of 5.2% performance improvement across 6 VideoQA benchmarks while having 4x faster training time and 18x less inference FLOPs. TrajViT is the first efficient encoder to consistently outperform ViT3D across diverse video analysis tasks, making it a robust and scalable solution.

4:07-4:19: Untangling Machine Knitted Objects, Nat Hurtig

Abstract: Machine knitting is a staple technology of modern textile production where hundreds of mechanical needles are manipulated to form yarn into interlocking loop structures. Manually programming these machines to form knitted objects can be difficult and error-prone, and compilers for high-level tools are limited. We define formal semantics for machine knitting programs using category theory. We present an algorithm that canonicalizes the knitted objects that programs make, untangling topological equivalence in polynomial time.

4:19-4:31: HoloGarment: 360-Degree Novel View Synthesis of In-the-Wild Garments, Johanna Karras

Abstract: HoloGarment (Hologram-Garment) is a method for generating canonical, static 360-degree garment visualizations from 1-3 images or even a dynamic video of a person wearing a garment. This is a challenging task, due to (1) frequent occlusions, non-rigid deformations, and significant pose variations present in real-world garments, and (2) the scarcity of ground-truth paired image-3D data. Our key insight is to bridge the domain gap between real and synthetic data with a novel implicit training paradigm leveraging a combination of large-scale real video data and small-scale synthetic 3D data to optimize a shared garment embedding space. During inference, the shared embedding space further enables the construction of a garment “atlas” representation by finetuning a garment embedding on a specific real-world video. The atlas captures garment-specific geometry and texture across all viewpoints, independent of body pose or motion. Extensive experiments show that HoloGarment achieves state-of-the-art performance on NVS of in-the-wild garments from images and videos, even in the presence of challenging real-world artifacts.

Abstract: AI agents that can reason, plan, and take actions over extended time horizons have gained considerable excitement as a paradigm that can usher in a new generation of useful AI applications. However, agentic systems’ real-world success depends not only on their inherent capabilities, but also their ability to effectively collaborate with humans. In this talk, I first offer a 5-level framework for thinking about autonomy in AI agents, characterized by the roles a user can take when interacting with an agent. I argue that, rather than designing agents to operate at a specific level, the community should enable agents to move fluidly and appropriately across levels. I then introduce agent notebooks as an interaction technique for doing so. I share Cocoa, an agentic system for scientific researchers that implements agent notebooks, which improves agent steerability over chat-based baselines. I conclude with promising directions for future research in human-agent collaboration.
