The problem is here hosted on kaggle. Description¶. We will prepare dataset, upload images, train classifier and test our classifier in the web interface. Most of the Latin word recognition and character recognition have used k-nearest neighbor classifier and other classification algorithms. The classi-fication of these patterns is done through a novel two stage classifier in which K Nearest Neightbour (KNN) acts as the first step and finds out the two most fre-quently represented classes amongst the K nearest patterns, followed by the per-. image registration issue that occurs while the dependencies between intensities of images to be registered are not spatially homogeneous. SVM is fundamentally a binary classification algorithm.
