#### Description

Like the course I just released on **Hidden Markov Models**, **Recurrent Neural Networks** are all about learning sequences – but whereas Markov Models are limited by the Markov assumption, Recurrent Neural Networks are not – and as a result, they are more expressive and more powerful than anything we’ve seen on tasks that we haven’t made progress on in decades.

So what’s going to be in this course and how will it build on the previous neural network courses and Hidden Markov Models?

In the first section of the course, we are going to add the concept of **time** to our neural networks.

I’ll introduce you to the **Simple Recurrent Unit**, also known as the **Elman unit**.

We are going to revisit the XOR problem, but we’re going to extend it so that it becomes the parity problem – you’ll see that regular **feedforward neural networks** will have trouble solving this problem but recurrent networks will work because the key is to treat the input as a sequence.

#### In the next section of the course, we are going to revisit one of the most popular applications of recurrent neural networks – **language modeling**.

You saw when we studied Markov Models that we could do things like generate poetry and it didn’t look too bad. We could even discriminate between 2 different poets just from the sequence of parts-of-speech tags they used.

In this course, we are going to extend our language model so that it no longer makes the Markov assumption.

Another popular application of neural networks for language is **word vectors** or **word embeddings**.

We’ll apply these to some more practical problems, such as learning a language model from **Wikipedia data** and visualizing the word embeddings we get as a result.

We will do most of our work in **Numpy,** **Matplotlib**, and **Theano**. I am always available to answer your questions and help you along your data science journey.

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’s not about “remembering facts”, it’s about **“seeing for yourself” via experimentation**. It will teach you how to visualize what’s happening in the model internally. If you want **more** than just a superficial look at machine learning models, this course is for you python course.

See you in class!

#### Suggested Prerequisites:

- matrix addition, multiplication
- probability (conditional and joint distributions)
- Python coding: if/else, loops, lists, dicts, sets
- Numpy coding: matrix and vector operations, loading a CSV file
- Can write a neural network in Theano or Tensorflow

#### TIPS (for getting through the course):

- Watch it at 2x.
- Take handwritten notes. This will drastically increase your ability to retain the information.
- Write down the equations. If you don’t, I guarantee it will just look like gibberish.
- Ask lots of questions on the discussion board. The more the better!
- Realize that most exercises will take you days or weeks to complete.
- Write code yourself, don’t just sit there and look at my code.

WHAT ORDER SHOULD I TAKE YOUR COURSES IN?:

- Check out the lecture “What order should I take your courses in?” (available in the Appendix of any of my courses, including the free Numpy course)
