WebNov 17, 2024 · 1. t-SNE is often used to provide a pretty picture that fits an interpretation which is already known beforehand; but that is obviously a bit of a shady application. If you want to use it to actually learn something about your data you didn't already know (e.g., identify outliers), you face two problems: t-SNE generates very different pictures ... WebJun 25, 2024 · T-distributed Stochastic Neighbourhood Embedding (tSNE) is an unsupervised Machine Learning algorithm developed in 2008 by Laurens van der Maaten and Geoffery Hinton. It has become widely used in bioinformatics and more generally in data science to visualise the structure of high dimensional data in 2 or 3 dimensions. flagpole ideas for front yard
