I am a newbie. I think idea of NuPIC is really cool and therefore wanted to apply KNN Classifier on NuPIC's output. I saw there is a KNNClassifier object already in python. I am confused about the input patter that I should use. In case of MNIST dataset I will be having images where each image is a 2D array of numbers and will be sparse. I can understand the format of output can be encoded using categorical encoder in NuPIC but there is no such example of encoding an input that comes in the form of arrays.
Any help will be highly appreciated.
