- Aug 13, 2014 · Defining a distance to compare objects of interest is an important problem in machine learning. Many metric learning algorithms were proposed to tackle this problem by considering labeled datasets, most of which exploit the simple and intuitive framework of Mahalanobis distances (Xing et al. 2002; Schultz and Joachims 2003; Kwok 2003; Goldberger et al. 2004; Shalev-Shwartz et al. 2004 ...

- A local directional pattern was used to extract the features from face regions to discriminate the illumination changes. These approaches were well used to identify the illumination changes, intensity distributions characteristics. Here, matching was done between input and original samples using Euclidean distance metrics.
Use the MATLAB princomp function. Compute its K-dimensional projection of the test images onto the face space. For each test image, find the training image that is ``closest'' (in the sense of Euclidean distance) to the test image in the face space, and assign the label (person index) of the training image to the test image.

In time series analysis, dynamic time warping (DTW) is one of the algorithms for measuring similarity between two temporal sequences, which may vary in speed. For instance, similarities in walking could be detected using DTW, even if one person was walking faster than the other, or if there were accelerations and decelerations during the course of an observation.
