Deep Studying with R, 2nd Version

Right this moment we’re happy to announce the launch of Deep Studying with R,
2nd Version. In comparison with the primary version,
the ebook is over a 3rd longer, with greater than 75% new content material. It’s
not a lot an up to date version as a complete new ebook.

This ebook exhibits you how you can get began with deep studying in R, even when
you don’t have any background in arithmetic or information science. The ebook covers:

• Deep studying from first ideas

• Picture classification and picture segmentation

• Time collection forecasting

• Textual content classification and machine translation

• Textual content technology, neural type switch, and picture technology

Solely modest R data is assumed; the whole lot else is defined from
the bottom up with examples that plainly reveal the mechanics.
Find out about gradients and backpropogation—by utilizing tf$GradientTape()
to rediscover Earth’s gravity acceleration fixed (9.8 (m/s^2)). Be taught
what a keras Layer is—by implementing one from scratch utilizing solely
base R. Be taught the distinction between batch normalization and layer
normalization, what layer_lstm() does, what occurs once you name
match(), and so forth—all by implementations in plain R code.

Each part within the ebook has acquired main updates. The chapters on
laptop imaginative and prescient achieve a full walk-through of how you can strategy a picture
segmentation process. Sections on picture classification have been up to date to
use {tfdatasets} and Keras preprocessing layers, demonstrating not simply
how you can compose an environment friendly and quick information pipeline, but additionally how you can
adapt it when your dataset requires it.

The chapters on textual content fashions have been fully reworked. Discover ways to
preprocess uncooked textual content for deep studying, first by implementing a textual content
vectorization layer utilizing solely base R, earlier than utilizing
keras::layer_text_vectorization() in 9 other ways. Find out about
embedding layers by implementing a customized
layer_positional_embedding(). Be taught in regards to the transformer structure
by implementing a customized layer_transformer_encoder() and
layer_transformer_decoder(). And alongside the best way put all of it collectively by
coaching textual content fashions—first, a movie-review sentiment classifier, then,
an English-to-Spanish translator, and at last, a movie-review textual content
generator.

Generative fashions have their very own devoted chapter, masking not solely
textual content technology, but additionally variational auto encoders (VAE), generative
adversarial networks (GAN), and magnificence switch.

Alongside every step of the best way, you’ll discover sprinkled intuitions distilled
from expertise and empirical statement about what works, what
doesn’t, and why. Solutions to questions like: when do you have to use
bag-of-words as a substitute of a sequence structure? When is it higher to
use a pretrained mannequin as a substitute of coaching a mannequin from scratch? When
do you have to use GRU as a substitute of LSTM? When is it higher to make use of separable
convolution as a substitute of standard convolution? When coaching is unstable,
what troubleshooting steps do you have to take? What are you able to do to make
coaching quicker?

The ebook shuns magic and hand-waving, and as a substitute pulls again the curtain
on each crucial basic idea wanted to use deep studying.
After working by the fabric within the ebook, you’ll not solely know
how you can apply deep studying to widespread duties, but additionally have the context to
go and apply deep studying to new domains and new issues.
