Occam's Razor     The principle that when faced with multiple but equivalent interpretations of some phenomenon, one should always choose the simplest explanation that correctly fits the data. Occam's Razor is useful for selecting competing models for some phenomena.

One-to-One     A function or map that for every possible output has only one input that yields that particular output; if f(a) = f(b), then a = b.

Optimization     The process of finding parameters that minimizes or maximizes a function.

Outer Product     An operation on two vectors that yields a matrix. Given two vectors with the same dimensionality, the outer product is a square symmetric matrix that contains the product of all pairs of elements from the two vectors, i.e., A[i,j] = x[i] y[j].
