Latent Semantic Analysis (LSA) is a document analysis technique that's based on a bag-of-words assumption. What does that mean? LSA is a way to take a set of written documents, and find...

What is LU Decomposition? LU Decomposition is simply the process of factoring a matrix *A* into an upper triangular matrix *U*, and a lower triangular matrix *L* so that *L×U = A*. Ok, well, why should I care? Many engineering applications...

Numerical differentation has a cornucopia of uses in engineering. However, when you're first learning it may appear daunting - especially the form of the equations. For instance, these...

Cluster analysis is some powerful voodoo, and has been applied to a *ton* of different areas. Market analysis? Cluster it...
