WebLearning rate for optimization process, specified as a positive scalar. Typically, set values from 100 through 1000. When LearnRate is too small, tsne can converge to a poor local minimum. When LearnRate is too large, the optimization can initially have the Kullback-Leibler divergence increase rather than decrease. See tsne Settings. Example: 1000 WebJan 22, 2024 · Step 3. Now here is the difference between the SNE and t-SNE algorithms.

WebJan 26, 2024 · A low learning rate will cause the algorithm to search slowly and very carefully, however, it might get stuck in a local optimal solution. With a high learning rate the algorithm might never be able to find the best solution. The learning rate should be tuned based on the size of the dataset. Here they suggest using learning rate = N/12.
