Help with Matrix Multiplications

[Deepti_Prasad]

hi @cg_macdonald

check if this thread helps you debug your codes. Read Paul’s comment for the thread to understand while matrix multiplication you are not suppose to use incorrect function as that cause incorrect calculations and converts your vector into scalar

To close the loop on the public thread here, the issue was that the z and h values were calculated as scalars (the sum over the samples). We need to maintain them as vectors, so that we can see the separate predictions per sample.

if still having issue then let us know
