Let's first import a few libraries. Now we load the classic handwritten digits datasets. It contains 1797 images with \(8*8=64\)pixels each. Here are the images: Now let's run the t-SNE algorithm on the dataset. It just takes one line with scikit-learn. Here is a utility function used to display the transformed dataset. The … See more Let's explain how the algorithm works. First, a few definitions. A data point is a point \(x_i\) in the original data space \(\mathbf{R}^D\), where \(D=64\) is the dimensionality of the … See more Let's assume that our map points are all connected with springs. The stiffness of a spring connecting points \(i\) and \(j\) depends on the mismatch between the similarity of the two data points and the similarity of the two … See more The following function computes the similarity with a constant \(\sigma\). We now compute the similarity with a \(\sigma_i\) depending on the data point (found via a binary … See more Remarkably, this physical analogy stems naturally from the mathematical algorithm. It corresponds to minimizing the Kullback-Leiber divergence between the two distributions … See more WebContribute to athanzxyt/tsne_clustering development by creating an account on GitHub.
