Introduction

The field of Deep Learning has progressed exponentially, and so has the footprint of ML models like BERT, GPT-3, ResNet, etc. While they work great, training and deploying these large (and growing) models in production is expensive. You might want to deploy your face filter model on smartphones to let your users add a puppy filter on their selfies. But it might be too big or too slow, or you might want to improve the quality of your cloud-based spam detection model but you don’t want to pay for a bigger cloud VM to host a more accurate but larger model. What if you don’t have enough labeled data for your models, or can’t manually tune your models? All this is daunting!

What if you could make your models more efficient: use less resources (model size, latency, training time, data, manual involvement) and deliver better quality (accuracy, precision, recall, etc.). That sounds wonderful! But how?

This book will go through algorithms and techniques used by researchers and engineers at Google Research, Facebook AI Research (FAIR), and other eminent AI labs to train and deploy their models on devices ranging from large server-side machines to tiny microcontrollers. In this book we present a balance of fundamentals as well as practical know-how to fully equip you to go ahead and optimize your model training and deployment workflows such that your models perform as well or better than earlier, with a fraction of resources. We also will present deep dives into popular models, infrastructure, and hardware, along with challenging projects to test your skills.

The Minimally Qualified Reader

The minimally qualified reader is someone who has a basic understanding of ML and at least some experience of training deep learning models. They can do basic fine-tuning of models by changing common parameters, can make minor changes to model architectures, etc. and get the modified models to train to a good accuracy. However, they are running into problems with productionizing these models / want to optimize them further. This is primarily because the book does not teach deep learning basics, for which we would like to refer you to excellent resources like Deep Learning with Python, Dive into Deep Learning, etc. Any reader having this pre-requisite knowledge would be able to enjoy the book.
