Web使用t-SNE时，除了指定你想要降维的维度（参数n_components），另一个重要的参数是困惑度（Perplexity，参数perplexity）。. 困惑度大致表示如何在局部或者全局位面上平衡关注点，再说的具体一点就是关于对每个点周围邻居数量猜测。. 困惑度对最终成图有着复杂的 ... WebSep 5, 2024 · Two most important parameter of T-SNE. 1. Perplexity: Number of points whose distances I want to preserve them in low dimension space.. 2. step size: basically is the number of iteration and at every iteration, it tries to reach a better solution.. Note: when perplexity is small, suppose 2, then only 2 neighborhood point distance preserve in low …
