Performs a pixel-wise Vector Quantization (VQ) of an image of the summer palace (China), reducing the number of colors required to show the image from 96,615

This example employs several unsupervised learning techniques to extract the stock market structure from variations in historical quotes. The quantity

Both kernel ridge regression (KRR) and SVR learn a non-linear function by employing the kernel trick, i.e., they learn a linear function in the

This is an example showing how the scikit-learn can be used to classify documents by topics using a bag-of-words approach. This example

Demonstrates the effect of different metrics on the hierarchical clustering. The example is engineered to show the effect of the choice

This example compares the timing of Birch (with and without the global clustering step) and MiniBatchKMeans on a synthetic dataset having 100,000 samples and

The plots below illustrate the effect the parameter C has on the separation line. A large value of C basically tells our model that we do not have

Sample usage of Nearest Centroid classification. It will plot the decision boundaries for each class.

Example builds a swiss roll dataset and runs hierarchical clustering on their position. For more information, see
