Course 2 3 weeks

Introduction to Natural Language Processing

This section provides an overview of the program and introduces the fundamentals of Natural Language Processing through symbolic manipulation, including text cleaning, normalization, and tokenization. You'll then build a part of speech tagger using hidden Markov models.

Lesson 1

Intro to NLP

Arpan will give you an overview of how to build a Natural Language Processing pipeline.

Lesson 2

Text Processing

Learn to prepare text obtained from different sources for further processing, by cleaning, normalizing and splitting it into individual words or tokens.

Lesson 3

Spam Classifier with Naive Bayes

In this section, you'll learn how to build a spam email classifier using the naive Bayes algorithm.

Lesson 4

Part of Speech Tagging with HMMs

Learn Hidden Markov Models, and apply them to part-of-speech tagging, a very popular problem in Natural Language Processing.

Lesson 5 • Project

Project: Part of Speech Tagging

In this project, you'll build a hidden Markov model for part of speech tagging with a universal tagset.

Lesson 6

(Optional) IBM Watson Bookworm Lab

Learn how to build a simple question-answering agent using IBM Watson.

Course 3 4 weeks

Computing With Natural Language

Learn advanced techniques like word embeddings, deep learning attention, and more. Build a machine translation model using recurrent neural network architectures.

Lesson 1

Introduction to Computing With Natural Language

An introduction of the course outline and prerequisite.

Lesson 2

Feature extraction and embeddings

Transform text using methods like Bag-of-Words, TF-IDF, Word2Vec and GloVE to extract features that you can use in machine learning models.

Lesson 3

Topic Modeling

In this section, you'll learn to split a collection of documents into topics using Latent Dirichlet Analysis (LDA). In the lab, you'll be able to apply this model to a dataset of news articles.

Lesson 4

Sentiment Analysis

Learn about using several machine learning classifiers, including Recurrent Neural Networks, to predict the sentiment in text. Apply this to a dataset of movie reviews.

Lesson 5

Sequence to Sequence

Here you'll learn about a specific architecture of RNNs for generating one sequence from another sequence. These RNNs are useful for chatbots, machine translation, and more!

Lesson 6

Deep Learning Attention

Attention is one of the most important recent innovations in deep learning. In this section, you'll learn attention, and you'll go over a basic implementation of it in the lab.

Lesson 7

RNN Keras Lab

This section will prepare you for the Machine Translation project. Here you will get hands-on practice with RNNs in Keras.

Lesson 8 • Project

Project: Machine Translation

Apply the skills you've learned in Natural Language Processing to the challenging and extremely rewarding task of Machine Translation.

Course 4 4 weeks

Communicating with Natural Language

Learn voice user interface techniques that turn speech into text and vice versa. Build a speech recognition model using deep neural networks.

Lesson 1

Course Introduction

Introduce the course outline and the course prerequisite

Lesson 2

Intro to Voice User Interfaces

Get acquainted with the principles and applications of VUI, and get introduced to Alexa skills.

Lesson 3

(Optional) Alexa History Skill

Build your own Alexa skill and deploy it!

Lesson 4

Speech Recognition

Learn how an automatic speech recognition (ASR) pipeline works.

Lesson 5 • Project

Project: DNN Speech Recognizer

Build a deep neural network that functions as part of an end-to-end automatic speech recognition pipeline.
