I have been developing and testing models for the financial market for some time. An accuracy of more than 90% seems impossible to me for such simple graphic samples (with little data). I replicated your model and got to 53%. By the way, the same thing was described in the "RandomForest Classifier results" issue. I began to doubt the results of this work. Can you explain these results?

Your code :

Your master thesis :

The file run_binary_preprocessing.py is using Format String F (Literal String Interpolation) that is available just 3.6+ and the project runs on 3.5.

running the first step python run_binary_preprocessing.py 2880.TW 20 50 only generates one sample image, the folder "0" and "1" are empty.

Thanks for making this work open-source.
I have tried to replicate your results using Taiwanese datasets.
I have generated images with dimension size of 50 and a period size of 20.
I have done testing with a random forest classifier.
I have tried a different number of estimators to check the improvement of the result.
I get accuracy around 0.55 with the shared Taiwanese dataset.
I would like to know whether you have a guess about what I could be missing?
I would like to know also why there is such a big gap between my results using the exact same pipeline and the results mentioned in the paper.

could this please be updated to work with a somewhat recent keras version?

thanks

UserWarning: Update your Conv2D call to the Keras 2 API...

would it be possible to get a complete example? I keep running in all kind of issues, from keras warnings, over methods not found errors, missing requirements, etc.
