Tsne precomputed
WebOct 15, 2024 · It has already been mentioned that the Euclidean distance is used by default in the Sklearn library. In addition, various distances can be used by setting dissimilarities = “precomputed”. In the code block below, MDS is applied to the fetch_olivetti_faces dataset in the sklearn library at various distances and visualized in 2D. WebIf the metric is ‘precomputed’ X must be a square distance matrix. Otherwise it contains a sample per row. If the method is ‘exact’, X may be a sparse matrix of type ‘csr’, ‘csc’ or ‘coo’. If the method is ‘barnes_hut’ and the metric is ‘precomputed’, X may be a precomputed sparse graph. yIgnored Returns

Webprecomputed (Boolean) – Tell Mapper whether the data that you are clustering on is a precomputed distance matrix. If set to True , the assumption is that you are also telling your clusterer that metric=’precomputed’ (which is an argument for DBSCAN among others), which will then cause the clusterer to expect a square distance matrix for each hypercube.
