Overview of this book

Deep learning is a branch of machine learning algorithms based on learning multiple levels of abstraction. Neural networks, which are at the core of deep learning, are being used in predictive analytics, computer vision, natural language processing, time series forecasting, and to perform a myriad of other complex tasks. This book is conceived for developers, data analysts, machine learning practitioners and deep learning enthusiasts who want to build powerful, robust, and accurate predictive models with the power of TensorFlow, combined with other open source Python libraries. Throughout the book, you’ll learn how to develop deep learning applications for machine learning systems using Feedforward Neural Networks, Convolutional Neural Networks, Recurrent Neural Networks, Autoencoders, and Factorization Machines. Discover how to attain deep learning programming on GPU in a distributed way. You'll come away with an in-depth knowledge of machine learning techniques and the skills to apply them to real-world projects.

Inception-v3


The Inception micro-architecture was first introduced by Szegedy and others in their 2014 paper, Going Deeper with Convolutions:

Figure 15: Original Inception module used in GoogLeNet

The goal of the inception module is to act as a multi-level feature extractor by computing 1×1, 3×3, and 5×5 convolutions within the same module of the network—the output of these filters is then stacked along the channel dimension before being fed into the next layer in the network. The original incarnation of this architecture was called GoogLeNet, but subsequent manifestations have simply been called Inception vN, where N refers to the version number put out by Google.

You might wonder why we are using different types of convolution on the same input. The answer is that it is not always possible to obtain enough useful features to perform an accurate classification with a single convolution, as far as its parameters have been carefully studied. In fact, with some input it works better with convolutions...
