Graph laplacian regularization term
Webthe intra-cluster relationships, we introduce a k-cluster Laplacian constraint to learn a graph with exact k connected groups. The learned graph is added to the multi-task learning framework as a regularization term to control the relation-ship between tasks. Then, we learn the graph and stock prediction models in an alternating fashion. WebMay 29, 2024 · A graph-originated penalty matrix \(Q\) allows imposing similarity between coefficients of variables which are similar (or connected), based on some graph given. …
