It successfully uncovers hidden structures in the data, exposing natural clusters and smooth nonlinear variations along the dimensions. It has been implemented in many languages, including Python, and it can be easily used thanks to the scikit-learn library.

WebMar 26, 2024 · When I visualize the embeddings using tensorboard t-sne I can see that they are clustered quite well as in the image. However, when I train the svm (with rbf kernel and grid search) I obtain an f1-score of 60% that given the figure seems quite low. Is it common to obtain good cluster with t-sne and bad results with svm? WebApr 7, 2024 · Image par auteur

WebThe learning rate for t-SNE is usually in the range [10.0, 1000.0]. If the learning rate is too high, the data may look like a ‘ball’ with any point approximately equidistant from its nearest neighbours.
