Hey everyone,
This video is a walkthrough tutorial of multi class logistic regression in python which is a supervised machine learning task . Multi class logistic regression, also known as multinomial and multivariate classification or regression where the goal is to identify different objects into more than 2 classes e.g. a given image is of an apple orange or banana?
This video covers the implementation of this algorithm from start to finish in python without using any libraries like Scikit learn or Keras.
Classifier will be trained and tested on famous MNIST dataset which consists of images of hand written digits from 0 to 9. We will work with the pixel intensity values of each image and from that we will try to classify what digit the given picture is of. To make this work for the images of all the digits we will be using the strategy called one vs all, details of which are discussed in depth in the video.
Finally we will be checking the accuracy of our classifier that how good is it performing, which is very well in fact.
If this video proved any valuable then do give this video a thumbs up and dont forget to subscribe too, you definitely wouldn't want to miss the cool videos which are on their way ;)

There's a slight repetition of clip where Im explaining about the dataset which somehow managed to sneak past the final edit phase, so skip that
