There are thousands of online courses which teach you how to build and train a machine learning model or deep neural network, many of these tutorials end with you just training and building the model alone. This, however, ends you having a model file on your local computer, which isn’t the end of the story: the model needs to be deployed in order to be used by the clients or end-users.

A big part of machine learning is classification — we want to know what class or group an observation belongs to. The ability to precisely classify observations is extremely valuable for various business applications like predicting whether a particular user will buy a product or forecasting whether a given loan will default or not.

Data science provides a plethora of classification algorithms such as logistic regression, support vector machine, naive Bayes classifier, and decision trees. But near the top of the classifier hierarchy is the random forest classifier.

In this post, we will examine how Random Forests algorithm works, and…

What is Sentiment Analysis?

A process of computationally identifying and categorizing emotions and opinions expressed in a piece of text, especially in order to determine whether the writer’s attitude towards a particular topic, product, etc. is positive, negative, or neutral.
