torch is an R port of PyTorch, one of the two most-employed deep learning frameworks in industry and research. It is also an excellent tool to use in scientific computations. It is written entirely in R and C/C++.

Though still "young" as a project, R torch already has a vibrant community of users and developers. Experience shows that torch users come from a broad range of different backgrounds. This book aims to be useful to (almost) everyone. Globally speaking, its purposes are threefold:

Provide a thorough introduction to torch basics

– both by carefully explaining underlying concepts and ideas, and showing enough examples for the reader to become "fluent" in torch

Show how to use torch in deep-learning applications

ranging from image recognition over time series prediction to audio classification

Provide a concepts-first, reader-friendly introduction to selected scientific-computation topics

(namely, matrix computations, the Discrete Fourier Transform, and wavelets), all accompanied by torch code you can play with.

Deep Learning and Scientific Computing with R torch is written with first-hand technical expertise and in an engaging, fun-to-read way.
