Tsne information loss
WebAs expected, the 3-D embedding has lower loss. View the embeddings. Use RGB colors [1 0 0], [0 1 0], and [0 0 1].. For the 3-D plot, convert the species to numeric values using the categorical command, then convert the numeric values to RGB colors using the sparse function as follows. If v is a vector of positive integers 1, 2, or 3, corresponding to the … WebT-SNE however has some limitations which includes slow computation time, its inability to meaningfully represent very large datasets and loss of large scale information [299]. A multi-view Stochastic Neighbor Embedding (mSNE) was proposed by [299] and experimental results revealed that it was effective for scene recognition as well as data visualization …

WebApr 13, 2024 · t-SNE is a great tool to understand high-dimensional datasets. It might be less useful when you want to perform dimensionality reduction for ML training (cannot be reapplied in the same way). It’s not deterministic and iterative so each time it runs, it could produce a different result. http://alexanderfabisch.github.io/t-sne-in-scikit-learn.html
