We propose a new universal architecture based on Graph Neural Network, the Message Passing Transformer, which incorporates a Message Passing framework, employs an Encoder-Processor-Decoder structure, and applies Graph Fourier Loss as loss function for model optimization. To take advantage of the past message passing state information, we propose Hadamard-Product Attention to update the node attribute in the Processor, Hadamard-Product Attention is a variant of Dot-Product Attention that focuses ","authors_text":"Yifei Li, Zeyi Xu","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2024-06-10T07:14:56Z","title":"Learning Physical Simulation with Message Passing Transformer"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2406.06060","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:b8fb7728b51ed67edb9fba0180960a02a63497b814bddf95d12271ecdb1bb822","target":"record","created_at":"2026-07-05T08:29:37Z","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":"7de0680a5ff9b8d7ce79e02bcaaa9b25c9f2ca0640ca41a0ba642f6c007d616e","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2024-06-10T07:14:56Z","title_canon_sha256":"da843e5bea93294e4d17aa57cbbfc4aa037f31e3b888b4b47f5056871b5fb805"},"schema_version":"1.0","source":{"id":"2406.06060","kind":"arxiv","version":1}},"canonical_sha256":"9228d66e4c8fb18e5d2233b7ebab2b8d12b0cc6f1735d3802d94c223579d29c1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9228d66e4c8fb18e5d2233b7ebab2b8d12b0cc6f1735d3802d94c223579d29c1","first_computed_at":"2026-07-05T08:29:37.288019Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T08:29:37.288019Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"yvLsVIomLGV85mZcGPwWT0XSgAzNpIas+CRBK/rcPnPKH5x7n5Atq4dU42Qq45tE6QlrpHERgEeYhVaH4vKwDQ==","signature_status":"signed_v1","signed_at":"2026-07-05T08:29:37.288430Z","signed_message":"canonical_sha256_bytes"},"source_id":"2406.06060","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b8fb7728b51ed67edb9fba0180960a02a63497b814bddf95d12271ecdb1bb822","sha256:5e82b97c0e868b7e50bd7ba643572a08bd99657a3742a26493031ae9478edf8d"],"state_sha256":"db6b65939635f4fe7aa7220c071337234c83c0fd32b85aba85a40281aa8c15ef"}
