Abstract: Real-time movie recommendation systems must efficiently handle large amounts of sparse user-item interaction data while maintaining great prediction accuracy. Conventional collaborative ...
Primary Algorithm : Algorithmically, Sparse-Sparse multiplication problems manifests itself in three possible forms:(a) Multiplication of a sparse matrix with a sparse diagonal, sparse block-diagonal, ...
Abstract: The Zak transform can directly map signals from the delay-Doppler domain to the time domain, which has a relatively low complexity for orthogonal time frequency space (OTFS) signal ...
