Voting between classifiers : How to prove it works?

Assume $m$ independent binary classifiers with probability $p$ to be correct $p>0.5$. Show that the probability of a voting, e.g. decision is made by the majority of classifiers is correct with probability $q>p$. I think this problem as equivalent…

Does KNN fail if the test data have no epsilon close nearest neighbors to the training data?

If I have binary-classification data and a Euclidean metric, and I know the best number of nearest neighbors, then I draw circles on my training data based on my K-value which tell me which regions are from class A and B via voting. How does KNN do…

Ensemble, what are simple alternatives to averaging?

I have a classification problem (A or B or C). I am currently evaluating test set results from the trained random forest, neural net, and logistic regression models. Any one model works pretty well on test set when I require an A or a B call to…
