This is a simple dataset, and one might argue that neural networks could also yield impressive results. Pre-trained models and datasets built by Google and the community if any are lists, they must all be lists of the same length, and if any are dicts they must all be dicts with the same set of keys. How to find the parent class name with known class in jQuery ? compile ( optimizer, loss = None, metrics = None, loss_weights = None, sample_weight_mode = None, weighted_metrics = None, target_tensors = None ) The important arguments are as follows . In the comprehensive guide, you can see how to prune some layers for model accuracy improvements. I tried to replace 'accuracy' with a few other classical metrics such as 'recall' or 'auc', but that didn't work. No. However, pruning makes most of the weights zeros, which is Why is recompilation of dependent code considered bad design? Then, create a compressible model for TFLite. L1 regularization adds a cost proportional to the absolute value of the weights. The text was updated successfully, but these errors were encountered: Is this still an issue with latest version TF 2.4?
