Introduction to Deep Neural Networks
Neural Networks are the fundamental building block of Deep Learning. In this class, you’ll learn their structure, and how to build them and train them. We’ll start the class by solving linear classification problems using perceptrons and logistic regression. From there, we’ll extend to solving highly non-linear classification problems using deep neural networks. We’ll learn about their architecture, how to train them using techniques such as gradient descent and backpropagation, and how to optimize the training process using different error functions and regularization techniques.
Lab: Building Neural Networks in Keras
You’ll finish this lesson with a coding lab where you’ll have the chance to apply all these concepts in Keras, one of the most popular Deep Learning packages in Python.
Convolutional Neural Networks
Convolutional Neural Networks are widely used for image classification, among many other exciting applications. In this section you’ll learn how they differ from ordinary neural networks. After exploring some new types of layers, we’ll explore several different network architectures. You’ll discover how to augment your data to improve performance, before learning techniques to visualize what your networks learn. You’ll learn to tap into the power of transfer learning, by benefitting from pre-trained networks such as VGGNet or ResNet.
Project: Build a Dog Recognition App
You’ll apply what you’ve learned to build an end-to-end algorithm to process any user-supplied image. Given an image of a dog, your algorithm will identify an estimate of the canine’s breed. If supplied an image of a human, the code will identify the resembling dog breed. What kind of dog will your algorithm think you look like? :)
Recurrent Neural Networks
Recurrent Neural Networks are used for some very exciting applications, such as time series predictions and sequence generation. Their architecture is different from feedforward neural networks, as the information cycles through the network, allowing it to remember previous states.
Project — Part 1: Predicting Apple Stock
You’ll apply what you’ve learned to build an algorithm which will perform time series predictions, and will forecast the stock price of Apple 7 days in advance.
Project — Part 2: Generating Sherlock Holmes text
You’ll also implement a recurrent neural network to create an English language generator, which will build semi-coherent English sentences from scratch. You’ll be able to test it by feeding it with the text of Sir Arthur Conan Doyle’s classic book, The Adventures of Sherlock Holmes, in order to obtain text that resembles a Sherlock Holmes novel! Elementary, my dear IBM Watson! :)
Concentration 1: Voice User Interfaces with Amazon Alexa
In this concentration, you’ll learn how computers can process speech, turn it into text, and vice versa. In the first part, you’ll get an overview of Voice User Interfaces (VUI), focus on Conversational AI, and learn how Alexa operates. Then, you’ll dive deeper into the exciting field of Speech Recognition, learning Signal Analysis and Phonetics, single word classification using Dynamic Time Warping, and sentence recognition using Hidden Markov Models. Finally, you’ll learn about the cutting edge in Automatic Speech Recognition, leveraging deep neural networks.
Amazon Alexa Project — Building an Alexa Skill
You’ll get your hands on the the Alexa Skills Kit, where you’ll build and deploy your first Alexa Skill, which will carry on a small conversation with the user and provide a fact from a given year.
Capstone Project — Converting Speech to English Text
In this project, you’ll have the opportunity to build an end to end-to-end Deep Learning based speech recognition system on a more constrained problem domain.
Concentration 2: Natural Language Processing with IBM Watson
Natural Language Processing (NLP) is a fascinating field in which we teach computers to understand and analyze text. In this concentration, you’ll learn to decompose a problem that involves analyzing natural language text into tasks, perform fundamental NLP operations, such as building an N-gram language model from a given corpus, and labelling words in a sentence with Part-of-Speech (POS) tags and as named entities. You will accomplish end-to-end NLP tasks such as document classification, machine translation, etc., using a combination of custom processing and cloud-based APIs.
IBM Watson Project — Question-Answering Agent with Watson
In this project, you will build a simple question-answering agent that is able to learn from any text data you provide, and answer queries posed in natural language. You will use IBM Watson’s cloud-based services to process the input text data and find relevant responses.
Capstone Project — Sentiment Analysis using Recurrent Neural Networks
With the rise of online social platforms like Twitter, Facebook, and Reddit, we now have access, more than ever before, to massive text-based data sets that can be analyzed in order to determine how large portions of the population feel about certain products, events, etc. This sort of analysis, commonly referred to as sentiment analysis, is the subject of this project. You will combine your knowledge of RNNs and what you have learned in this concentration about the foundations of NLP to build an end-to-end sentiment classification system.
Concentration 3: Computer Vision with Affectiva
Inspired by human vision, Computer Vision aims to give machines the ability to see and interpret the world by extracting information from images. In this concentration, you’ll learn the fundamentals of computer vision and the role it plays in artificial intelligence systems. Computer vision is used in many applications, from detecting skin cancer to emotion recognition (and even self-driving car navigation!). Throughout this term, you’ll develop practical skills and get hands-on coding experience with many of these real-world applications. You’ll learn to break down any problem that involves visual perception into computer vision tasks, such as: enhancing images, applying color and geometric transformations to change the appearance of an image, detecting object boundaries, computing gradients and filtering images, and extracting features like object edges and unique visual patterns. We’ll go over these foundational computer vision techniques in detail. Then, you’ll utilize what you’ve learned to create a complete AI system that uses computer vision to perform smart object detection and activity recognition.
Affectiva Emotion API Project — Mimic Me!
In this project, you’ll learn to track faces in a video and identify facial expressions (joy, sadness, surprise, etc.) using AffedexMe from Affectiva. As a fun visualization, it will be up to you to tag each identified face with its appropriate emoji! Then, you’ll turn this into a game where a player needs to mimic a random emoji displayed by the computer.
Capstone Project — Automatic Image Captioning
Image caption generation is an active field of research and a complex computer vision problem. Automatic captioning requires both object and activity recognition, and an understanding of what makes a good caption. For this project, you’ll be using a combination of computer vision techniques and deep neural networks to produce realistic captions.
Students in this program will master an in-depth curriculum that covers both the foundations and the cutting-edge advancements of Deep Learning. This kind of hands-on exposure to one of the most transformational technologies of our time makes this program a unique learning opportunity for anyone excited by the possibilities of AI. We invite you to join us as we prepare the next generation of AI experts who will power the amazing innovations ahead!
