WebJan 21, 2024 · 3.2.4 Visualization of Single Cell RNA-seq Data Using t-SNE or PCA. Both t-SNE and PCA are used for visualization of single cell RNA-seq data, which greatly facilitate identification of cellular heterogeneity, searching new cell type, inferring cell relationship and so on. PCA is widely used for visualization of single cell data during early ... WebDescription. Wrapper for the C++ implementation of Barnes-Hut t-Distributed Stochastic Neighbor Embedding. t-SNE is a method for constructing a low dimensional embedding of high-dimensional data, distances or similarities.

TSNE in the other hand creates low dimension embedding that tries to respect (at a certain level) the distance between the points in the real dimensions. TSNE doesn't look at points given their position in the high dimension space it just looks at the distance between that point and its neighbors. laws of behavioral investing
