Modern deep learning model performance is very dependent on the choice of model hyperparameters, and the tuning process is a major bottleneck in the machine learning pipeline. In this talk, we will overview modern methods for hyperparameter tuning and demonstrate how to use Tune, a scalable hyperparameter tuning library. Tune is completely open source at http://tune.io.
This talk will target intermediate to advanced data scientists and researchers familiar with deep learning. The talk will first motivate the need for advancements in hyperparameter tuning methods. The talk will then overview standard methods for hyperparameter tuning: grid search, random search, and bayesian optimization. Then, we will motivate and discuss cutting edge methods for hyperparameter tuning: multi-fidelity bayesian optimization, successive halving algorithms (HyperBand), and population-based training.
The talk will then present a overview of Tune, a scalable hyperparameter tuning system from the UC Berkeley RISELab, and demonstrate about how users can leverage cutting edge hyperparameter tuning methods implemented in Tune to quickly improve the performance of standard deep learning models.
