Evaluation of Contextual Bandit algorithms on the CIFAR-100 dataset, specifically focusing on the last 100 episodes, measured by Average Cost.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Contextual Bandit |
| Dataset (including any stated split) | CIFAR-100 (Last 100 episodes) |
| Metric | Average Cost |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 3 of 3 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [Average Cost](<https://www.sota2.com/research/sota/contextual-bandit-on-cifar-100-last-100-episodes.md?metric=Average%20Cost>): Lower is better; unit: SCALAR.
