Rather than performing velocity regression in the conventional VAE latent space, PFM supervises flow matching in a perceptual feature space using pretrained perceptual models. This simple change substantially improves the few-step generation capability of flow-matching models, reducing the number of sampling steps from 35-50 to 4-8 while preserving generation quality. Unlike existing acceleration and distillation approaches, PFM requires neither teacher models nor auxili","authors_text":"Chuyang Zhao, Haoyang Huang, Hongfa Wang, Huilin Deng, Jianlong Yuan, Nan Duan, Siming Fu, Yifei Song, Yuan Zhang, Zhineng Chen","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2026-07-03T17:55:01Z","title":"Perceptual Flow Matching for Few-Step Generative Modeling"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.03524","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":"sha256:82cc039430c46db25d7093e9c2cbc9db817fb30c6c28a96289794110b88ea11a","target":"record","created_at":"2026-07-07T02:17:51Z","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":"0950a1ec109b86d8a22000ec799a337c3a15aaf83129c676ae767579b370e555","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2026-07-03T17:55:01Z","title_canon_sha256":"29202d08b46b3eb84dda5f3eb861e87efe037d759cb119aea8a02e4e5ff1f19c"},"schema_version":"1.0","source":{"id":"2607.03524","kind":"arxiv","version":1}},"canonical_sha256":"017dd91a5485950169c685a7f53e1572e7d4fcf6956c0b94bc3138ad1511b25d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"017dd91a5485950169c685a7f53e1572e7d4fcf6956c0b94bc3138ad1511b25d","first_computed_at":"2026-07-07T02:17:51.724445Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-07T02:17:51.724445Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"kfCmsPsj9UjYC1OI+fXAwvm6+Wz4+YyaSI5LAbu/nd7aeBfeOa85rAOhUcGSAA2ma0i9tnOOybKjO6TaGRhvCA==","signature_status":"signed_v1","signed_at":"2026-07-07T02:17:51.726052Z","signed_message":"canonical_sha256_bytes"},"source_id":"2607.03524","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:82cc039430c46db25d7093e9c2cbc9db817fb30c6c28a96289794110b88ea11a","sha256:895dee28a28b7f435fb7ed28d4b4f201cfc682219c6c101369772f21f7b817e8"],"state_sha256":"22c685346382d4d1eb8e18aaef2e9b138da023e28815742e218e979de1e7d6ae"}
