The Labeled Faces in the Wild face recognition dataset 5. Each picture is centered on a single face. The typical task is called Face Verification: given a pair of two pictures, a binary classifier must predict whether the two images are from the same person. An alternative task, Face Recognition or Face Identification is: given the picture of the face of an unknown person, identify the name of the person by referring to a gallery of previously seen pictures of identified persons. Both Face Verification and Face Recognition are tasks that are typically performed on the output of a model trained to perform Face Detection. The most popular model for Face Detection is called Viola-Jones and is implemented in the OpenCV library. The LFW faces were extracted by this face detector from various online websites.
This dataset size is more than 200 MB. The first load typically takes more than a couple of minutes to fully decode the relevant part of the JPEG files into numpy arrays.

Generators for classification and clustering 5. The 20 newsgroups text dataset 5. The Labeled Faces in the Wild face recognition dataset 5. Optical Recognition of Handwritten Digits Data Set 5. There are three distinct kinds of dataset interfaces for different types of datasets. See the dataset descriptions below for details. These datasets are useful to quickly illustrate the behavior of the various algorithms implemented in the scikit.
They are however often too small to be representative of real world machine learning tasks. The scikit also embed a couple of sample JPEG images published under Creative Commons license by their authors. Those image can be useful to test algorithms and pipeline on 2D data. Load sample images for image manipulation. Often machine learning algorithms work best if the input is converted to a floating point representation first. Also, if you plan to use matplotlib.
0 – 1 as done in the following example. In addition, scikit-learn includes various random sample generators that can be used to build artificial datasets of controlled size and complexity. These generators produce a matrix of features and corresponding discrete targets. Gaussian cluster into near-equal-size classes separated by concentric hyperspheres. Gaussian data with a spherical decision boundary for binary classification. The number of topics for each document is drawn from a Poisson distribution, and the topics themselves are drawn from a fixed random distribution. Similarly, the number of words is drawn from Poisson, with words drawn from a multinomial, where each topic defines a probability distribution over words.
Per-topic word distributions are independently drawn, where in reality all would be affected by a sparse base distribution, and would be correlated. For a document generated from multiple topics, all topics are weighted equally in generating its bag of words. Documents without labels words at random, rather than from a base distribution. Generate an array with constant block diagonal structure for biclustering. Generate an array with block checkerboard structure for biclustering. Other regression generators generate functions deterministically from randomized features. Generate a signal as a sparse combination of dictionary elements.
