The importance of metrics in machine learning and pattern recognition algorithms has led to an increasing interest for optimizing distance metrics in recent years. Most of the state-of-the-art methods focus on learning Mahalanobis distances and the learned metrics are in turn heavily used for the nearest neighbor-based classification (NN). However, until now no theoretical link has been established...
This Letter, for the first time, proves that a general invariant velocity is originated from principle of special relativity, namely, discovers origin of the general invariant velocity. When the general invariant velocity is taken as light velocity in current theories, we get the corresponding special theory of relativity. Further, this Letter deduces triple special theories of relativity in cosmology,...
