Common ML algorithms for NLP
There are so many machine learning algorithms that are out there and the main takeaway I want you to get from this lesson is that you can use any of these common machine learning algorithms for NLP. Once you've pre-processed your text data or gotten it from that text form to that numeric form, you can just input that numeric data or that document term matrix into a machine learning model just like we've been doing throughout this entire Data Science in Python series. Now let's walk through some of those machine learning algorithms at a high level. At the very top we have our overall umbrella of machine learning and like we talked about in the last lesson there are two main categories of machine learning. Supervised learning where you're making a prediction and unsupervised learning where you're finding patterns. Within supervised learning we can divide that into two more categories. There's regression techniques and classification techniques. Regression techniques help you predict a…
