## Acknowledgement
|
| 23 |
+
This model was developed as part of the STRADA project on self-supervised transformers for radio astronomy.

+
## Intended Use
|
| 27 |
+
STRADAViT is intended as a domain-adapted starting point for radio astronomy imaging tasks.
|
| 28 |
+
It is suitable for:
|
| 29 |
+
|
| 30 |
+
- frozen-backbone transfer via linear probing
|
| 31 |
+
- downstream fine-tuning for morphology classification
|
| 32 |
+
- reuse as a vision backbone in broader radio astronomy pipelines, including detection and segmentation models
|
| 33 |
+
|
| 34 |
+
## Limitations
|
| 35 |
+
STRADAViT is trained for transfer on radio astronomy imaging and should not be assumed to
|
| 36 |
+
outperform all off-the-shelf vision backbones in every downstream setting. In the current study:
|
| 37 |
+
|
| 38 |
+
- gains are strongest under frozen-backbone evaluation
|
| 39 |
+
- fine-tuning gains are more dataset-dependent
|
| 40 |
+
- performance remains sensitive to view generation and dataset heterogeneity
|
| 41 |
+
- broader validation on additional surveys and downstream tasks is still needed
