T-sne for feature visualization
WebOct 31, 2024 · What is t-SNE used for? t distributed Stochastic Neighbor Embedding (t-SNE) is a technique to visualize higher-dimensional features in two or three-dimensional space. … I want to use a real world dataset because I had used this technique in one of my recent projects at work, but I can’t use that dataset because of IP reasons. So we’ll use the famous MNIST dataset . (Well even though it has become a toy dataset now, it is diverse enough to show the approach.) It consists of 70,000 … See more I won’t be explaining the training code. So let’s start with the visualization. We will require a few libraries to be imported. I’m using PyTorch Lightningin my scripts, … See more We looked at t-SNE and PCA to visualize embeddings/feature vectors obtained from neural networks.
