Let’s Start and Understand how Multi-class Image classification can be performed. The pixel values are on a gray scale in which 0 represents white, 255 represents black, and values between 0 and 255 represent shades of gray. One way to create a system that can classify the digit imsges into 10 classes (from 0 to 9) is to train 10 binary classifiers, one for each digit ( a 0 – detector, a 1 – detector, and so on). LSTM (Long Short Term Memory) LSTM was designed to overcome the problems of simple Recurrent Network (RNN) by allowing the network to store data in a sort of memory … In order to get sufficient accuracy, without overfitting requires a lot of training data.
