combining their neurons there are sort of these subspaces that are sort of spanned by their neurons so I'm so so this is going to be at a very high level the details of like all the the the mathematical details of CCA are in their relevant papers but so at a very high level what we do is we take in two sets of these neuron activity vectors and they're typically going to be layers so layer from one network a layer from another network and then CCA will find the linear combination of these neurons that maximizes correlation and by
