Orthogonal Matching Pursuit In orthogonal matching pursuit (OMP), the residual is always orthogonal to the span of the atoms already selected. This results in convergence for a d -dimensional vector after at most d steps. Conceptually, you can do this by using Gram-Schmidt to create an orthonormal set of atoms.

The adaptive greedy approximation uses the matching pursuit algorithm, MPALG. The dictionary, MPDICT, is typically an overcomplete set of vectors constructed using wmpdictionary. [ YFIT, R ] = wmpalg(...) returns the residual, R, which is the difference vector between Y and YFIT at the termination of the matching pursuit.

We present a robust kernel-based method, which exploits greedy selection techniques, particularly Orthogonal Matching Pursuit (OMP), in order to recover the sparse support of the outlying vector; at the same time, it approximates the non-linear function via …

Nov 02, 2014 · The goal of a support vector machine is to find the optimal separating hyperplane which maximizes the margin of the training data. The first thing we can see from this definition, is that a SVM needs training data. Which means it is a supervised learning algorithm. It is also important to know that SVM is a classification algorithm.

Support-vector machine weights have also been used to interpret SVM models in the past. Posthoc interpretation of support-vector machine models in order to identify features used by the model to make predictions is a relatively new area of research with special significance in the biological sciences.
