Tensorflow gradient clip

WebThe clipping factor for regular gradient clipping is sensitive to batch size, model depth, learning rate, etc. I wanted to investigate the relationship between batch size and clipping factor and their correlation with the final test accuracy. Using Weights and Biases Sweep I was able to quickly set up my ablation study. WebClips tensor values to a maximum L2-norm. Pre-trained models and datasets built by Google and the community
