Deep Learning Quick Reference

By: Mike Bernico

Overview of this book

Deep learning has become an essential necessity to enter the world of artificial intelligence. With this book deep learning techniques will become more accessible, practical, and relevant to practicing data scientists. It moves deep learning from academia to the real world through practical examples. You will learn how Tensor Board is used to monitor the training of deep neural networks and solve binary classification problems using deep learning. Readers will then learn to optimize hyperparameters in their deep learning models. The book then takes the readers through the practical implementation of training CNN's, RNN's, and LSTM's with word embeddings and seq2seq models from scratch. Later the book explores advanced topics such as Deep Q Network to solve an autonomous agent problem and how to use two adversarial networks to generate artificial images that appear real. For implementation purposes, we look at popular Python-based deep learning frameworks such as Keras and Tensorflow, Each chapter provides best practices and safe choices to help readers make the right decision while training deep neural networks. By the end of this book, you will be able to solve real-world problems quickly with deep neural networks.

A refresher on time series problems

Time series problems are problems involving a sequence of data points placed in temporal order. We most often represent those data points as a set:

Usually our goal in time series analysis is forecasting; however, there are certainly many other interesting things you can do with a time series that are outside the scope of this book. Forecasting is really just a specialized form of regression, where our goal is to predict some point xt or points , given some set of previous points . We can do this when the time series is auto correlated, which means the data points are correlated with themselves one or more points back in time (which are called lags). The stronger the auto correlation, the easier it is to forecast.

In many books, time series problems are denoted with y, rather than x, as a hint towards the idea that we typically care to predict...
