In this post willl show how KNN simple prediction model could be improved with kinetic energy and kullback leibler divergence for classification tasks in general and for image recognition tasks in particular. Added simple starter code on github repo class KineticKnn(object): def __init__(self,train,test,kinetic,KLdiv,optim_percent): self.train=train self.test=test self.optimization_percent=optimization_percent self.KLdivergence=Kldivergence self.kinetic=kinetic As you notticed in this simple class are feeded as parameters : train , test- the data sets where the training and predicting will tacke place kinetic and KLdiv are boolean values , optim_percent - number like 0.2 meaning holdout data set in order to optimize on it .
