wush978/FeatureHashing: Creates a Model Matrix via Feature Hashing with a Formula Interface
Version 0.9.1.3

Feature hashing, also called as the hashing trick, is a method to transform features of a instance to a vector. Thus, it is a method to transform a real dataset to a matrix. Without looking up the indices in an associative array, it applies a hash function to the features and uses their hash values as indices directly. The method of feature hashing in this package was proposed in Weinberger et al. (2009) . The hashing algorithm is the murmurhash3 from the 'digest' package. Please see the README in for more information.
