Sparse Coding

INTRODUCTION Sparse coding is one of the very famous unsupervised methods in this decade, it is a dictionary learning process, which target is to find a dictionary that we can use a linear combination of vectors in this┬ádictionary to represent any training input vector. For better capture structures and patterns inherent in the input vectors, […]

K-Means Clustering

ABOUT UNSUPERVISED LEARNING In supervised learning problems, we deal with┬álabeled data, means during the training process, we give our machine both Xs and Ys, by training, we ‘forge’ a system, which given new Xs, it is able to guess the output Ys. By using better algorithm and sophisticated methods, we can make the forged system […]
