### Data Science: Deep Learning in Python

In this course, you will build SEVERAL hands-on systems using natural language processing, or NLP – the branch of machine learning and data science that deals with text and speech. This course is not in my deep learning series, so it doesn’t contain difficult math – just coding in Python. All material for this course is FREE.

After a brief discussion of what NLP is and what it can do, we’ll start creating some really useful stuff. The first thing we’re going to create is an encrypted decryption algorithm. These have applications in warfare and espionage. We will learn how to build and apply several useful NLP tools in this section, namely character level language models (using Markov’s principle) and genetic algorithms.

The second project, in which we start to use more traditional “machine learning”, is to build a spam detector. You probably receive very little spam these days, compared to the early 2000s, because of systems like these.

Next, we’ll create a sentiment analysis model in Python. It’s something that allows us to assign a score to a block of text that tells us how positive or negative it is. People have used sentiment analysis on Twitter to predict the stock market.

We’ll go over some handy tools and techniques like the NLTK (natural language toolkit) library and Latent Semantic Analysis or LSA.

Finally, we end the course by building an article spinner. It is a very difficult problem and even the most popular products these days do not do it correctly. These lectures are designed to get you started and to give you ideas on how you could improve them yourself. Once mastered, you can use it as an SEO or search engine optimization tool. Internet marketers around the world will love you if you can do it for them!

This course focuses on “how to build and understand”, not just “how to use”. Anyone can learn to use an API in 15 minutes after reading some documentation. It is not a question of “remembering the facts”, but of “seeing for yourself” through experimentation. It will teach you how to visualize what is going on in the model internally. If you want more than just a cursory glimpse into machine learning models, this course is for you.

You will learn

Write your own decryption algorithm using genetic algorithms and language modeling with Markov models

Write your own spam detection code in Python

Write your own sentiment analysis code in Python

Perform latent semantic analysis or latent semantic indexing in Python

Get an idea of how to write your own article spinner in Python
