Summary: | Using computer simulations of a minimal computational model of hippocampal region CA3, this report investigates how randomization during training alters learned performance. The transitive inference problem is employed for this purpose. Randomizing just the initial network state at the beginning of each training trial profoundly affects learning. That is, no randomization makes the problem unlearnable while a moderate amount of randomized activity optimizes network performance. These results suggest a way to alter learning which may be tested in neuropsychological experiments. |
