Scalable, customizable hyperparameter tuning
We cite all the algorithms that we’re using. We give you total information about what’s happening as the sweep is running, so you have complete control.
It’s easy to get started. We’ve dealt with the edge cases, so you don’t have to worry about concurrent runs and crashing runs.
Our sweeps are infinitely customizable. You can pick your own distribution for inputs, specify logic, and use early stopping.
Visualize which hyperparameters affect the metrics you care about. W&B comes with default visualizations that make it easy to get started without writing custom code to compare experiments.
Use our transparent implementations of popular algorithms, or customize your own logic for sweeps.
We implemented the Hyperband algorithm
to save GPU hours with customizable early stopping. This feature keeps the most promising, best performing runs running and kills off the bottom runs. Agents are then freed up to try new hyperparameter combinations.
Our sweeps can handle massive scale, and we support early stopping so you can quickly try thousands of hyperparameter combinations without wasting GPU hours.
Visualize everything in one unified place with our dashboard.
