Nearest Neighbor Classification Using Cam Weighted Distance
Nearest Neighbor (NN) classification assumes class conditional probabilities to be locally constant, and suffers from bias in high dimensions with a small sample set. In this paper, we propose a novel cam weig...

Classifying Unbalanced Pattern Groups by Training Neural Network
When training set is unbalanced, the conventional least square error (LSE) training strategy is less efficient to train neural network (NN) for classification because it often lead the NN to overcompensate for...
