Gradient Ascent for Bayes Nets
Let 183#183 denote one entry in the conditional probability table for
variable 181#181 in the network
184#184
e.g., if
185#185, then 186#186 might be
187#187
Perform gradient ascent by repeatedly
- update all 183#183 using training data 5#5
188#188
- then, renormalize the 183#183 to assure
