Visualizing Data using t-SNE An Intuitive Introduction Simon Carbonnelle Universit e Catholique de Louvain, ICTEAM 12th of May, 2016. t-SNE is Discussion 7. It is a Data Visualization Technique t-SNE stands for t-stochastic neighbor embedding Developed by Laurens van der Maaten and Geoffrey Hinton in 2008. The name stands for t -distributed Stochastic Neighbor Embedding. You are expected to identify hidden patterns in the data, explore and analyze the dataset. The similarity of datapoint x jto datapoint x i is the conditional probability, p |i, that x i would pick x It is a variation to SNE (Stochastic Neighbor Embedding - Hinton and Roweis, 2002) In this tutorial, we'll briefly learn how to fit and visualize data with TSNE in Python. Although t-SNE has demonstrated to be a favorable technique for data visualization, there are three potential weaknesses with this technique. Because t-SNE is able to provide a 2D or 3D visual representation of high-dimensional data that preserves the original structure, we can use it during initial data exploration. Contrary to PCA it is not a mathematical technique but a probablistic one. t-SNE is also unsupervised, meaning it does not consider the class labels. Visualizing Data using t-SNE Laurens van der Maaten L.VANDERMAATEN@MICC UNIMAAS NL MICC-IKAT Maastricht University P.O. t -SNE stands for t -distributed Stochastic Neighbor Embedding. The basic idea of t-SNE is to reduce dimensional space keeping relative pairwise distance between points. t-SNE is capable of capturing much of the local structure of the high-dimensional data very well, while also revealing global structure such as the presence of clusters at several scales. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We present a new technique called “t-SNE” that visualizes high-dimensional data by giving each datapoint a location in a two or three-dimensional map. This is mostly useful for us humans to spot patterns in data, since we have a hard time visualizing data with >2 dimensions. The original paper describes the working of t-SNE as: MNIST handwritten digit dataset works well for this purpose and we can use Keras API's MNIST data. We'll collect the output component data in a dataframe, then we use 'seaborn' library's scatterplot() to plot the data. Laurens van der Maaten, Geoffrey Hinton; 9(86):2579−2605, 2008. wise similarities and we introduce a new technique, called “t-SNE”, for visualizing the resulting similarity data. Now, we'll project it into two dimensions with TSNE and visualize it in a plot.
