Document Summary
Generalization = transfer of past learning to new situation and problem. *core issue= find an appropriate balance btw specificity . Discrimination = the perception of difference btw stimuli. Collaborative filtering: auto filter use in amazon based on info from large no of other people past behavior and create a very detailed stereotype of you. Trained pigeon respond to yellow light for food reinforcement , they also respond to light similar to yellow. As the color grew increasingly different, the respond decrease. *generalization gradient= curve showing how change in the physical property of stimuli correspond to changes in responding. Measure person perception of similarity in that if 2 stimuli perceived as highly similar, there will be significant generalization btw them. Challenge of generalization= consequential region: to identity the set of all stimuli that have the same consequence as the training stimulus.
