Posit AI Blog Site: TensorFlow and Keras 2.9

The release of Deep Knowing with R, second
Edition accompanies brand-new releases of
TensorFlow and Keras. These releases bring numerous improvements that permit
for more idiomatic and succinct R code.

Initially, the set of Tensor techniques for base R generics has considerably
broadened. The set of R generics that deal with TensorFlow Tensors is now
rather substantial:

 techniques( class  = " tensorflow.tensor")

 [1] -!!= [           [<-        
 [6] */ & &%/%%
%.[11] < <^ + <  >=|abs acos.
[16] all any aperm Arg asin.
[21] atan cbind ceiling Conj cos.
[26] cospi digamma dim exp expm1.
[31] flooring Im is.finite is.infinite is.nan.
[36] length lgamma log log10 log1p.
[41] log2 max indicate minutes Mod.
[46] print prod variety rbind Re.
[51] associate round indication sin sinpi.
[56] sort sqrt str amount t.
[61] tan tanpi [66] This implies that typically you can compose the very same code for TensorFlow Tensors.
as you would for R selections. For instance, consider this little function.
from Chapter 11 of the book: 

reweight_distribution

<%  {
   exp( log( ) / temperature level )
    }  %>>%
       { ./ amount() }  }  Keep in mind that functions like   reweight_distribution()  deal with both 1D R.
vectors and 1D TensorFlow Tensors, considering that 
       exp() ,   log() , /, and.
 amount()  are all R generics with techniques for TensorFlow Tensors.
   In the very same vein, this Keras release brings with it an improvement to the.
method customized class extensions to Keras are specified. Partly motivated by.
the brand-new 

R7 syntax, there is a.
brand-new household of functions: new_layer_class(), new_model_class(),.
new_metric_class(), and so on. This brand-new user interface significantly.
streamlines the quantity of boilerplate code needed to specify customized.
Keras extensions-- an enjoyable R user interface that acts as an exterior over.
the mechanics of sub-classing Python classes. This brand-new user interface is the.
yang to the yin of % py_class%-- a method to mime the Python class.
meaning syntax in R. Naturally, the "raw" API of transforming an.
R6Class()

to Python by means of r_to_py() is still offered for users that.
need complete control. This release likewise brings with it a cornucopia of little enhancements.
throughout the Keras R user interface: upgraded print() and plot() techniques.
for designs, improvements to freeze_weights() and load_model_tf(),.
brand-new exported energies like zip_lists() and %<>< >%

And let’s not.
forget to point out a brand-new household of R functions for customizing the knowing.
rate throughout training, with a suite of integrated schedules like.
learning_rate_schedule_cosine_decay(), matched by a user interface.
for producing customized schedules with new_learning_rate_schedule_class() You can discover the complete release notes for the R plans here: The release notes for the R plans inform just half the story nevertheless.
The R user interfaces to Keras and TensorFlow work by embedding a complete Python.
procedure in R (by means of the.
reticulate bundle). Among.
the significant advantages of this style is that R users have complete access to.
whatever in both R and Python. Simply put, the R user interface.
constantly has function parity with the Python user interface– anything you can.
make with TensorFlow in Python, you can do in R simply as quickly. This implies.
the release notes for the Python releases of TensorFlow are simply as.
