An alternative method for calculating a latent model relies on a mathematical miracle worker called the Singular Valued Decomposition (SVD) - what is this? Let's look at a graphical explanation. Here's what you get if you try and find the main parts of the “Lena” image (a famous image ...

Feature Hashing is a useful technique for dealing with sparse or "bag-of-words" type data-sets. The essential idea is to hash the features into a new feature space of a prespecified vector size. The algorithm employs hashing on two levels - the first is the hashing to the hash-space index, the second ...
