WebThe learning rate for t-SNE is usually in the range [10.0, 1000.0]. If the learning rate is too high, the data may look like a ‘ball’ with any point approximately equidistant from its nearest neighbours. If the learning rate is too low, most points may look compressed in a dense cloud with few outliers. WebInstallation. For the analysis portion, you need the following python libraries installed: scikit-learn, keras, numpy, and simplejson. The openFrameworks application only requires one addon: ofxJSON.
