WebUMAP and t-SNE are very similar to eachother but UMAP is faster, less sensitive to hyperparameters, and does a better job at preserving high-dimension relationships between clusters. Both UMAP and t-SNE are fairly quick and easy to use. UMAP also has a tiny bit more theoretical justification, but honestly the topology stuff is beyond me. Webthrough a wireless network and cloud storage media. The t-SNE_VAE_bi-LSTM model is proposed in this study as a prediction model that combines the t-SNE, VAE, and bi-LSTM networks.
