Although transformer-based architectures, such as SwinUNETR, achieved impressive results, few studies test how well they generalize across clinical protocols. In this paper, we conduct an ablation study on the MU-GLIOMA-POST and UCSF-ALPTDG datasets and show that the standard Generalized Dice Loss (GDL) is unstable under domain shift: the Whole Lesion (WL) Dice drops from 0.88 on the internal validation set to 0.73 on the external UCSF te","authors_text":"Alexandru Cri\\c{s}an, Diana Borza","cross_cats":["cs.AI"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2026-07-23T09:59:30Z","title":"Post-Operative Glioma Segmentation via Loss Stabilization, Normalization and Subspace Attention"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.22749","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:c794af00a9e9ec663793c35989dd878a7cfac4eb76bcc67441b79d0b094bab3a","target":"record","created_at":"2026-07-28T00:21:52Z","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":"757ea7eabcd9b5394f57186b6af182e04a042741efc285078d6297399dbe0bf2","cross_cats_sorted":["cs.AI"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2026-07-23T09:59:30Z","title_canon_sha256":"e235b2a6290823b1bcebb9a305330a179be2878a2e5dc45612611179e3e177df"},"schema_version":"1.0","source":{"id":"2607.22749","kind":"arxiv","version":1}},"canonical_sha256":"ad72489063126c53cdde377cf33a4820804626e986dbdd3a47374e62dc88c03f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ad72489063126c53cdde377cf33a4820804626e986dbdd3a47374e62dc88c03f","first_computed_at":"2026-07-28T00:21:52.570501Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-28T00:21:52.570501Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"wiwlvDAVVVGLKBTwbZHrFLwp1KNvzJnj/f07XT/hrhiuHuZc3S2bM7XCOWDuwkCtJq/uJE4sXdJGuXQkIlulAQ==","signature_status":"signed_v1","signed_at":"2026-07-28T00:21:52.571440Z","signed_message":"canonical_sha256_bytes"},"source_id":"2607.22749","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c794af00a9e9ec663793c35989dd878a7cfac4eb76bcc67441b79d0b094bab3a","sha256:d6821a0bbfdef3d9d8e53b9af7913eaf275a2cb7d4152a61bb12c924494f0eb0"],"state_sha256":"76da5167d71980ca313547ad3b465578d1dee60ed3a9d9e0888d88ea2605d87f"}
