Coding Exercise on Barlow Twins

Challenge yourself in the coding exercise on Barlow Twins.

We'll cover the following...

The Barlow Twins objective function

Given the representations of distorted views of a batch, Z1Z_1 and Z2Z_2, and assuming they are mean-centered (zero mean and unit variance) along the batch, the Barlow Twins algorithm first computes a correlation matrix C\mathcal{C} ...
