Python (tested with 3.7); required libraries:pandas, numpy, h5py Other versions are likely to work well too. Since MATLAB and Python are cross-platform we expect MOSTest to run well on Windows and MacOS too. Install MOSTest To install MOSTest you simply download or git fetch this repository...
In this paper, the Python programming language was used for data preprocessing, model development, experimental runs, and evaluation. A variety of Python frameworks like Pandas and Numpy for data preprocessing and neural network frameworks like Tensorflow and Keras were used for model development and ...
