Dynamic Reweighting

Having optimized weights appears to be very important, especially the weight on old vs new data. However, these optimal weights may not be the same against all opposing bots, particularly the case of hitting adaptive vs non adaptive movement. If your kD-Tree provides dynamic weighting functionality, you could theoretically have good weightings vs opponents after a few rounds. (See my post in "Hard-coded segmentation") The difficulty is thus finding the optimal weights for hitting a given opponent in short learning period. One approach would be to change your weights after a missed wave in a similar manner to training neural networks. When a wave hits, and your bullet misses, in non firing ticks (during which you have extra calculation time) do kNN searches to see if the weight on a particular predictor would have caused a better (closer to correct GF, or perhaps DV) prediction if it was higher or lower. Then, look at the results the past several calculations and look for trends, to avoid training on noise.(This is somewhat similar to what Gaff's gun does, it stores results from the past 5 missed waves and trains the neural network with all of them on a miss(If I remember correctly...)) This seems like it would tend to converge on better weights, which might help fight opponents with adaptive movement. It also would partially alleviate the curse of dimensionality on kNN classification, by lowering the weights of unimportant predictors (against a particular opponent) to close to zero, essentially removing them. Does anyone else have ideas for optimizing weights during combat?
