How to add 2 tensors in R

This recipe helps you add 2 tensors in R

Recipe Objective - How to add 2 tensors in R?

Tensors are generally are generalization of the vectors and matrices to an arbitary number of dimensions(defined as "axis"). Tensors addition can be easily done using element wise operation for only identical tensors. sweep() function is used for adding unidentical tensors.

Build Expedia Hotel Recommendation System using Machine Learning

Steps for adding tensors.

Step 1: Create tensor a of the random values with shape (64, 3, 32, 10)

a <- array(round(runif(1000, 0, 9)), dim = c(60, 2, 34, 12))

Step 2: Create tensor y with shape (32, 10)

b <- array(5, dim = c(34, 12))

Step: Addition of tensors using pmax function

x <- sweep(x, c(3, 4), y, pmax)

The tensor addition is executed successfully using pmax function.
