      dataset that allows for a systematic comparision of PyTorch and Tensorflow models. The creation of the dataset will democratize the study of such framework-based semantic differences between neural network models despite syntactically identical network architectures, hyperparameters and optimization algorithms. The contributions from our dataset can be summarized as follows: • The ...
