Recently, large-scale pretrained foundation models have been leveraged as shared priors for perception, reasoning, and action, enabling zero-shot VLN without task-specific training. However, existing zero-shot VLN methods depend on costly perception and passive scene understanding, collapsing control to point-level choices. As a result, they are expensive to deploy, misaligned in action semantics, and short-s","authors_text":"Peiran Liu, Renjing Xu, Shuning Zhang, Taowen Wang, Yawen Tan, Yiding Ji, Yixiao Feng, Yuetong Fang, Yunheng Wang","cross_cats":["cs.AI","cs.CL","cs.CV"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.RO","submitted_at":"2025-09-14T09:54:20Z","title":"DreamNav: A Trajectory-Based Imaginative Framework for Zero-Shot Vision-and-Language Navigation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2509.11197","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:cc85f9e346ffe359ad575fca023c1a8f5bc38544977195dbab7add0f15d80a36","target":"record","created_at":"2026-07-05T12:11:35Z","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":"c51be59c47491e0632bb81bce829e3d6d78358cf4918be35fd8877568496cfcd","cross_cats_sorted":["cs.AI","cs.CL","cs.CV"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.RO","submitted_at":"2025-09-14T09:54:20Z","title_canon_sha256":"95dff1f176fd1ade3a4b21b3f7c0fda0b66a1725451e985ecc187d68dcedabfa"},"schema_version":"1.0","source":{"id":"2509.11197","kind":"arxiv","version":1}},"canonical_sha256":"dcfea1feb3f7899960584f5bb9c0c929b8de32a133862610be604d96604ea079","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"dcfea1feb3f7899960584f5bb9c0c929b8de32a133862610be604d96604ea079","first_computed_at":"2026-07-05T12:11:35.099245Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T12:11:35.099245Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"P4zs9nDVisGLzvBOdGkOnUuMn7y4IF4oKs1NIJqdh2azT5iFGD0awpqMXVJY9rh+Fookx0xSx1DOrPjviMR5Cg==","signature_status":"signed_v1","signed_at":"2026-07-05T12:11:35.099735Z","signed_message":"canonical_sha256_bytes"},"source_id":"2509.11197","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:cc85f9e346ffe359ad575fca023c1a8f5bc38544977195dbab7add0f15d80a36","sha256:fcb0fbf0f4940a91786ee3e9cfa6349497c5f130eb7863a47824c55453d0d0da"],"state_sha256":"b6edc70657545f574eb625450d41ee8a0f701fbe4f535e43d38143ea35fb6693"}
