Computing A Dtw Mat

Here are my comments about why the authors used 1 m instead of m.

Computing a dtw mat.

Hi quan this is a great piece of work and i have made slight changes to normalize the dtw distance by its warping path for both matlab and c versions for my project. Default is 1 i e. Please let me know if i can contribute that here. It specifies the number of cores to be used.

Dist dtw x y stretches two vectors x and y onto a common set of instants such that dist the sum of the euclidean distances between corresponding points is smallest to stretch the inputs dtw repeats each element of x and y as many times as necessary. In that case x and y must have the same number of rows. Dtw windowing control parameter. Normalized inner product or the cosine of the angle between them.

Is computing the cosine similarity i e. When computing dtw you want to find the lowest cost path through the cost matrix. Resistivity up to 1 x 10 9 ohms 1 000 000 000 ohms economical static dissipative mat available 3 8 thick available in 3 and 4 widths. Electrosoft is a truly dissipative sponge vinyl anti fatigue mat.

If x and y are matrices then dist stretches them by repeating their columns. In line 3 m simmx mfcc1 mfcc2. Not available in windows os. Controls whether parallel computing is applied.

Basically i m using a dynamic time warping algorithm like used in speech recognition to try to warp geological data filter out noise from environmental conditions the main difference between these two problems is that dtw prints a warping function that allows both vectors that are input to be warped whereas for the problem i m trying to solve i need to keep one reference vector.
