Dear friends, I’m sharing this great news that Google opens Embedding Projector for the world. Now everyone could enjoy the convenient approach to visualize high dimensional data on the web browser.
Based on my personal programming experience, t-SNE is a great method for high-dimensional data visualization, better than PCA on some data sets like MNIST.
You can download the Matlab Toolbox for Dimensionality Reduction; or download the t-SNE method for different platforms: t-SNE codes.
Moreover, check the following papers if you want to learn more details about dimensionality reduction.
