Evaluation of image compression models on the validation split of the GalaxyZoo GZ2 dataset, using metrics such as rate and various loss statistics.

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) | GalaxyZoo GZ2 (val) |
| Metric | Rate (Mb/img) |
| Unit | SIZE |
| Direction | Lower is better |
| Results loaded | 5 of 5 |
| 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

- [Rate (Mb/img)](<https://www.sota2.com/research/sota/image-compression-on-galaxyzoo-gz2-val.md?metric=Rate%20(Mb%2Fimg)>): Lower is better; unit: SIZE.

- [Validation Loss Mean](<https://www.sota2.com/research/sota/image-compression-on-galaxyzoo-gz2-val.md?metric=Validation%20Loss%20Mean>): Lower is better; unit: SCALAR.

- [Median (x10^-3)](<https://www.sota2.com/research/sota/image-compression-on-galaxyzoo-gz2-val.md?metric=Median%20(x10%5E-3)>): Higher is better; unit: SCALAR.

- [Maximum Value](<https://www.sota2.com/research/sota/image-compression-on-galaxyzoo-gz2-val.md?metric=Maximum%20Value>): Lower is better; unit: SCALAR.

- [Minimum Value (x10^-7)](<https://www.sota2.com/research/sota/image-compression-on-galaxyzoo-gz2-val.md?metric=Minimum%20Value%20(x10%5E-7)>): Lower is better; unit: SCALAR.

- [Standard Deviation (x10^-2)](<https://www.sota2.com/research/sota/image-compression-on-galaxyzoo-gz2-val.md?metric=Standard%20Deviation%20(x10%5E-2)>): Lower is better; unit: SCALAR.
