This paper investigates the novel use of attention as a form of feature augmentation, i.e, casted attention. We propose Multi-Cast Attention Networks (MCAN), a new attention mechanism and general model architecture for a potpourri of ranking tasks in the conversational modeling and question answering domains. Our approach performs a series of soft attention operations, each time casting a scalar feature upon the inner word embeddings. The key idea is to provide a real-valued hint (feature) to a subseque","authors_text":"Luu Anh Tuan, Siu Cheung Hui, Yi Tay","cross_cats":["cs.AI","cs.IR"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2018-06-03T12:22:28Z","title":"Multi-Cast Attention Networks for Retrieval-based Question Answering and Response Prediction"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1806.00778","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:d0d534a1cfd415615f32b923836d81041917dcaf02d48b03654e3bf37375a883","target":"record","created_at":"2026-05-18T00:14:18Z","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":"6bb0d04b92f41d7de71b0b572d16a4ae0465ccc8087fd5ad60ebaa51f20b8526","cross_cats_sorted":["cs.AI","cs.IR"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2018-06-03T12:22:28Z","title_canon_sha256":"ead3ca2a759b2e1bcc68474595de284ced27e0013556afdb2510d0e9ffb762be"},"schema_version":"1.0","source":{"id":"1806.00778","kind":"arxiv","version":1}},"canonical_sha256":"8339882ebf51bb8b77caae2d30e2b8f87f0d358b77b3baccc8abc9baf9af64ad","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8339882ebf51bb8b77caae2d30e2b8f87f0d358b77b3baccc8abc9baf9af64ad","first_computed_at":"2026-05-18T00:14:18.462900Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:14:18.462900Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"2PUzWy/6cs3zKdrjeaBrPNUI1oFoPIyxyyljjZp/NcBpk8S1ta2x1irM/rnHIFiywdzPdTnHcXRaCD/kr4RHDw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:14:18.463374Z","signed_message":"canonical_sha256_bytes"},"source_id":"1806.00778","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d0d534a1cfd415615f32b923836d81041917dcaf02d48b03654e3bf37375a883","sha256:71706616d34a3a5986dcdd434c6ef51140eb07e51a52009af3340c206a300bb4"],"state_sha256":"507460767b71d7a86e23adfe2746d098e5721a11421cc7e32863d0693e0e4c2a"}
