Web7 jun. 2024 · Easy Hyperparameter Tuning with Keras Tuner and TensorFlow (today’s post) Last week we learned how to use scikit-learn to interface with Keras and TensorFlow to perform a randomized cross-validated hyperparameter search. WebBy the way, hyperparameters are often tuned using random search or Bayesian optimization. I would use RMSProp and focus on tuning batch size (sizes like 32, 64, 128, 256 and 512), gradient clipping (on the interval 0.1-10) and dropout (on the interval of 0.1-0.6). The specifics of course depend on your data and model architecture.
