WebFeb 13, 2024 · tSNE and clustering. tSNE can give really nice results when we want to visualize many groups of multi-dimensional points. Once the 2D graph is done we might want to identify which points cluster in the tSNE blobs. Louvain community detection. TL;DR If <30K points, hierarchical clustering is robust, easy to use and with reasonable … WebJul 18, 2024 · 4) I saw you set the the regularization parameter C=100000. It's drastically reduce the regularization, as C is the inverse of regularization strength. It's expected to consume more iterations and may lead to overfit the model. 5) I didn't expect that a higher max_iter would get you lower accuracy. The solver is diverging rather than converging ...
