WebBasic t-SNE projections¶. t-SNE is a popular dimensionality reduction algorithm that arises from probability theory. Simply put, it projects the high-dimensional data points … WebMar 5, 2024 · In t-SNE, several parameters needs to be optimized (hyperparameter tuning) for building the effective model. perplexity is the most important parameter in t-SNE, and it measures the effective number of neighbors. The number of variables in the original high-dimensional data determines the perplexity parameter (standard range 10-100).
