conceptual understanding as well as practically using them in your deep learning models. We start with sparsity. If your goal was to optimize your brain for storage, you can often trim a lot of useless trivia etc. while retaining the model’s performance? In this chapter we introduce the intuition behind sparsity, different possible methods of picking the connections and nodes to prune, and how to prune a given get you excited yet? Let’s learn about these techniques together! Model Compression Using Sparsity Sparsity or Pruning refers to the technique of removing (pruning) weights during the model training

specifics X78Structured and Unstructured Sparsity - Lots of 'free' wins from exploring sparsity in modern ML models - Can often prune models to 80%+ sparsity(with retraining) - Massive speedups combined

sparse matrices differ from their dense counterparts in that the resulting matrix follows the same sparsity pattern as a given sparse matrix S, or that the resulting sparse matrix has density d, i.e. each dimensions m x n with structural zeros at S[I[k], J[k]]. This method can be used to construct the sparsity pattern of the matrix, and is more efficient than using e.g. sparse(I, J, zeros(length(I))). For C::Sparse, update::Cint) Update an LDLt or LLt Factorization F of A to a factorization of A ± C*C'. If sparsity preserving factorization is used, i.e. L*L' == P*A*P' then the new factor will be L*L' == P*A*P'
