I am trying to use the EMD applied to EURUSD open price to train a machine learning algo (RVM).

I have run only once the EMD on my training set and once on the training+test set.

The results on the test sets only are quite good. However when I apply the algo on the last sample only the predictions are bad.

Shall I run the EMD on each sample of my training set using a sliding window ?

I understand EMD is non-causal, but can it be used in some ways for training a machine learning algo ?

There is inherent massive lag in the calculation of the Hurst exponent (H), maybe this is your problem? How are you using EMD in your strategy, what method of EMD are you using, do you plan to use EMD in real time? FYI: I'm in the process of reinventing IMF part of the EMD method, specifically for capitalized markets for real time use. –  montyhall Mar 6 '13 at 21:43
