5 Different Ways To Save Your Machine Learning Model

Saving your trained machine learning models is an important step in the machine learning workflow: it permits you to reuse them in the future. For instance, it's highly likely you'll have to compare models to determine the champion model to take into production -- saving the models when they are trained makes this process easier. The alternative would be to train the model each time it needs to be used, which can significantly affect productivity, especially if the model takes a long time to train. In this post, we will cover 5 different ways you can save your trained models. Pickle is one of the most popular ways to serialize objects in Python; You can use Pickle to serialize your trained machine learning model and save it to a file. At a later time or in another script, you can deserialize the file to access the trained model and use it to make predictions.
