In this post i will be describing easiest way to create a digit recognizer using sci-kit learn.In this session i will be using random forest which is a good algorithm for classification and regression tasks. For those of you who are new to datascience and ML this will give a good introduction into topic.The dataset we will be using is MNIST. You can do a quick google search for MNIST dataset and download it.
