Using the MiraBest dataset, we generate captions with a domain-specific prompt and evaluate their alignment with images through the SigLIP-2 vision--language model, with and without LoRA fine-tuning. Results show that caption-based classification of FR-I and FR-II galaxies performs similarly to images, with fine-tuning improving local coherence of embeddings but not global alignment.","authors_text":"Erica Lastufka, Mariia Drozdova, Svyatoslav Volosynovskiy","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"astro-ph.IM","submitted_at":"2026-07-07T14:08:18Z","title":"Exploring Image-Text Alignment for Radio Galaxy Morphologies"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.06305","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:77f103732e126eb7809b3e983bcbe58a10c637949552a5602eafb3895d0f179b","target":"record","created_at":"2026-07-08T01:19:20Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"6fe2454e400d203c887170ba638e4166f8da6db6be75a2f455e76c461dc765fd","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"astro-ph.IM","submitted_at":"2026-07-07T14:08:18Z","title_canon_sha256":"c6bd47a40954ad88d2983ecb51fea9be9d844d12ef16cbf77ff498257920ff10"},"schema_version":"1.0","source":{"id":"2607.06305","kind":"arxiv","version":1}},"canonical_sha256":"28c73e0ba010edf4020a9f9d9c081ce92d71bbcc0a4ac0b1773c1d51818747b8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"28c73e0ba010edf4020a9f9d9c081ce92d71bbcc0a4ac0b1773c1d51818747b8","first_computed_at":"2026-07-08T01:19:20.548082Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-08T01:19:20.548082Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"pAE55ngynqLfR0k9nY0e+eTydIu1YoJj/Dsu0VlBDk3zN4qDGs/Yiw+qDAr6ULKI0coMGj4ZyEZyGK/BCTy0BA==","signature_status":"signed_v1","signed_at":"2026-07-08T01:19:20.548501Z","signed_message":"canonical_sha256_bytes"},"source_id":"2607.06305","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:77f103732e126eb7809b3e983bcbe58a10c637949552a5602eafb3895d0f179b","sha256:281e8d95d2c6875b4e75672a3523124c6ed3e4bfe4b9d595d551c8d278830d65"],"state_sha256":"aa4e4a0d331b7406cc260f42b9c00efef83cc4cc72e08af139462985c26bdf91"}
