Feature hashing is the encoding of multiple features into a single numeric ‘feature’ of a given range. Not really a feature, but a hash map. It’s particularly useful for compressing sparse matrices (matrices with many 0’s). For more information, read wikipedia’s hash table page and Hash Collision Probabilities .
