FeatureExtract function with "StandardizedVector" do not show the standard devaition of one

I am wondering what kind of scaling is applied to the FeatureExtract function with "StandardizedVector" option. The output does not show the standard devaition of one for each columns. This function is used in NetEncoder["FeatureExtractor"] also. x={{1., 2., 3.}, {4., 5., 6.}, {7., 8., 9.}, {10., 11., 12.}, {13., 14.,15.}} xS01 = FeatureExtract[x, "StandardizedVector"]; xS02 = Standardize[x]; StandardDeviation /@ {xS01, xS02} Mean /@ {xS01, xS02} // Chop {{1.11803, 1.11803, 1.11803}, {1., 1., 1.}} Thanks ..read more

Kalman Filtering as a Functional Fold
Wolfram Community » Machine Learning
by Brian Beckman
4d ago
The attached notebook demonstrates basic Kalman filtering -- parameter estimation specifically -- as a functional fold over lists, streams, and asynchronous observables. It exhibits applications from estimating the coefficients of a polynomial to tracking in 2D. It includes a concise redux of Kalman's theory. It is pedagogical in nature. &[Wolfram Notebook][1] [1]: https://www.wolframcloud.com/obj/58e7fba2-1304-4bd2-814e-bcdf066ee16a ..read more

[WSS18] Generating Music with Expressive Timing and Dynamics
Wolfram Community » Machine Learning
by Pavlo Apisov
4d ago
![Cover][1] ## Goal ## There are many ways to generate music and one of them is algorithmic, where music is generated with the help of a list of handcrafted rules. The approach in this project is different - I build a neural network that knows nothing about music but learns it from thousands of songs given in MIDI format. _Apart from just generating a meaningful sequence of notes I also wanted to add **dynamics** in loudness and humanlike mistakes in timing with **no restrictions for note durations**._ - **Why dynamics and timing?** There is no human who is able to play on a musical instrument ..read more
