Knowledge distillation in machine learning involves transferring knowledge from a large 'teacher' model to a smaller 'student' model.
One effective method for model compression is the Kronecker decomposition, which involves breaking down a large matrix into the Kronecker product of two smaller matrices.
The Kronecker decomposition significantly reduces the number of parameters stored, leading to reduced compute and storage requirements.
By defining a cost function and using techniques like Singular Value Decomposition (SVD), optimal A and B matrices can be obtained for the best least-squares approximation of the original weight matrix W.
