WebMNIST. MNIST is a simple computer vision dataset. It consists of 28x28 pixel images of handwritten digits, such as: Every MNIST data point, every image, can be thought of as an array of numbers describing how dark each pixel is. For example, we might think of Bad mglyph: img/mnist/1-1.png as something like: WebAug 19, 2024 · Multicore t-SNE . This is a multicore modification of Barnes-Hut t-SNE by L.
