Such incompleteness weakens item representations and degrades recommendation performance. Existing modality imputation methods estimate missing representations from available item content, but two challenges remain. First, they optimize the recovered representation itself without explicitly considering its relations with other modalities of the same item. The completed modalities may therefore form inconsistent cross-modal relations, causing Cross-mod","authors_text":"Miaomiao Cai, Ruiyu Liu, See-kiong Ng, Xiaohao Liu, Yunshan Ma","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IR","submitted_at":"2026-07-29T10:10:20Z","title":"CaIRec: Calibrated Modality Imputation for Incomplete Multimodal Recommendation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.26720","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":"sha256:4ae780eec78257389116e550bfe8e86bc7d9379f88d02cb3d8daf492c9d77ea3","target":"record","created_at":"2026-07-30T01:22:04Z","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":"d0d979812523cf4d10e9bbbf67d74d87d03421acae134eecd2d9f57414b2d1d0","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.IR","submitted_at":"2026-07-29T10:10:20Z","title_canon_sha256":"263bc63933f0e8e07c78517f92469761d3fe4bb93ef3e297e40d4d8220cd53e9"},"schema_version":"1.0","source":{"id":"2607.26720","kind":"arxiv","version":1}},"canonical_sha256":"1643f5a933e4244d573f542cd610115c553e8c5ab349b7e1ca20acd05b294c1e","receipt":{"builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1643f5a933e4244d573f542cd610115c553e8c5ab349b7e1ca20acd05b294c1e","first_computed_at":"2026-07-30T01:22:04.208491Z","kind":"pith_receipt","last_reissued_at":"2026-07-30T01:22:04.208491Z","receipt_version":"0.3","signature_status":"unsigned_v0"},"source_id":"2607.26720","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4ae780eec78257389116e550bfe8e86bc7d9379f88d02cb3d8daf492c9d77ea3","sha256:a610e517feedaf574b822d0f893c70c72353f2cdb626bcd8c7426b05e803b276"],"state_sha256":"bad0245a786ff8c5e55fbf3b51ce63df08b070d8a0c400c5d311b1409b8f9250"}
