WebOct 31, 2024 · t distributed Stochastic Neighbor Embedding (t-SNE) is a technique to visualize higher-dimensional features in two or three-dimensional space. It was first introduced by Laurens van der Maaten [4] and the Godfather of Deep Learning, Geoffrey Hinton [5], in 2008. Webt-SNE is described in (Van der Maaten & Hinton 2008), while the Barnes-Hut t-SNE implementation is described in (Van der Maaten 2014). To cite the Rtsne package specifically, use (Krijthe 2015). van der Maaten L, Hinton G (2008). “Visualizing High-Dimensional Data Using t-SNE.” Journal of Machine Learning Research, 9, 2579-2605. oracle challenge destiny 2
