Evaluation of image compression models on the test split of the ImageNet64 dataset, typically measured using NLL and BPD.

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 | Image Compression |
| Dataset (including any stated split) | ImageNet64 (test) |
| Metric | BPS |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 9 of 9 |
| 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

- [BPS](<https://www.sota2.com/research/sota/image-compression-on-imagenet64-test.md?metric=BPS>): Lower is better; unit: SCALAR.

- [NLL](<https://www.sota2.com/research/sota/image-compression-on-imagenet64-test.md?metric=NLL>): Lower is better; unit: SCALAR.

- [BPD](<https://www.sota2.com/research/sota/image-compression-on-imagenet64-test.md?metric=BPD>): Lower is better; unit: SCALAR.

- [Auxiliary Bits](<https://www.sota2.com/research/sota/image-compression-on-imagenet64-test.md?metric=Auxiliary%20Bits>): Lower is better; unit: SIZE.

- [Encoding Time (ms) Inference](<https://www.sota2.com/research/sota/image-compression-on-imagenet64-test.md?metric=Encoding%20Time%20(ms)%20Inference>): Lower is better; unit: TIME.

- [Encoding Time (ms) Coding](<https://www.sota2.com/research/sota/image-compression-on-imagenet64-test.md?metric=Encoding%20Time%20(ms)%20Coding>): Lower is better; unit: TIME.

- [Decoding Time (ms) Inference](<https://www.sota2.com/research/sota/image-compression-on-imagenet64-test.md?metric=Decoding%20Time%20(ms)%20Inference>): Lower is better; unit: TIME.

- [Decoding Time (ms) Coding](<https://www.sota2.com/research/sota/image-compression-on-imagenet64-test.md?metric=Decoding%20Time%20(ms)%20Coding>): Lower is better; unit: TIME.
