In order to improve reproducibility, deep reinforcement learning (RL) has been adopting better scientific practices such as standardized evaluation metrics and reporting. However, the process of hyperparameter

On top of that, individual models can be very slow to train. In this post you will discover how you can use the grid search capability from the scikit-learn python machine learning library to tune the hyperparameters of Keras deep learning models. After reading this post you will know: ...
Of course, hyperparameter tuning has implications outside of the k-NN algorithm as well. In the context of Deep Learning and Convolutional Neural Networks, we can easily have hundreds of various hyperparameters to tune and play with (although in practice we try to limit the number of variab...
The gains often get smaller the further down the list. For example, a new framing of your problem or more data is often going to give you more payoff than tuning the parameters of your best performing algorithm. Not always, but in general. ...
We do this by using a threshold. This threshold is a hyperparameter of the model and can be defined by the user. For example, the threshold could be 0.5–then any sample above or equal to 0.5 is given the positive label. Otherwise, it is negative. Here are the predicted labels for th...
Learn what is fine tuning and how to fine-tune a language model to improve its performance on your specific task. Know the steps involved and the benefits of using this technique.
(also referred to as Parameter Sweep). In this case we search for all the distinct and valid combinations of the given hyper-parameters based on the valid range of each provided by the user. For example, if the possible values for learning rate (lr) are {0.01, 0.05}, and the possible...
A learning process that’s iterative and controlled by numerous hyperparameters offers a way to shorten the feedback loop and speed up the trial-and-error cycle. You can easily set upTensorBoard, a popular visualization tool, along with Ray. Ray automatically exports training metrics such as eva...
—Practical recommendations for gradient-based training of deep architectures, 2012. In fact, if there are resources to tune hyperparameters, much of this time should be dedicated to tuning the learning rate. The learning rate is perhaps the most important hyperparameter. If you have time to tun...
