needed for supporting a WFO test: ve function(name) save(Models, filename) The ve function stores the Models list it now contains 2 models for long and for short trades after every training run in Zorros Data folder. The other approach, normally for experiments and research, is using only limited information from the price curve. Begin to train deep. All these parameters are common for neural networks. Its time for the 5th and final part of the. This is the approach that you normally find in the literature.

The NumCores variable at -1 activates all CPU cores but one. The output of the network is a sigmoid function since we want a prediction in the.1 range. So we must derive features from the price curve that contain more signal and less noise. Theres a plethora of possibilities, for instance: Use inputs from more candles and process them with far bigger networks with thousands of neurons. The adviseLong function is described in the Zorro manual ; it is a mighty function that automatically handles training and predicting and allows to use any R-based machine learning algorithm just as if it were a simple indicator.
This is the final script for training, testing, and (theoretically) trading the system ( DeepLearn. How pre-training works is easily explained, but why it works is a different matter. This turned out a revolutionary concept. A popular target, used in most papers, is the sign of the price return at the next bar.
