As episodes extend, this selection grows increasingly sparse, yet prior work shows no accuracy gain when scaling from 8 to 64 frames, suggesting the bottleneck is not frame quantity but the representation itself. Sparse frame selection cannot capture the structured behavioral signal that long-horizon reasoning requires: turning patterns, cumulative displacement, and path topology.\n  We introduce BIT-Nav (Brain-Inspired Trajectory Memory for Navigation), a framewor","authors_text":"Aakash Gurram, Man Namgung, Rithvik Jonna, Tinoosh Mohsenin, Wyatt Mackey","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.RO","submitted_at":"2026-06-19T13:06:02Z","title":"BIT-Nav: Brain-Inspired Trajectory Memory for Embodied Navigation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2606.21398","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":"sha256:6b168203235568eb5b2de35a42be59a5a6b71a245d4f3375e2deb5df4ec4117b","target":"record","created_at":"2026-06-23T01:13:08Z","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":"45a8f3ae2d0c06d44fa72fcad495c49ac00dc1ef1964c2430642d19d43c9d88e","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.RO","submitted_at":"2026-06-19T13:06:02Z","title_canon_sha256":"d46404a8f33425d4894e8b2728646ea71b21a53f76fe3a715617f928f701ce12"},"schema_version":"1.0","source":{"id":"2606.21398","kind":"arxiv","version":1}},"canonical_sha256":"9c7b9b35e4af170acd16384c3d062c392ef1ac06f2300198593d2ab1ad9e8e8b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9c7b9b35e4af170acd16384c3d062c392ef1ac06f2300198593d2ab1ad9e8e8b","first_computed_at":"2026-06-23T01:13:08.971153Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-23T01:13:08.971153Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"/S4GU9jBS60AHuah7bMkNLh1qeRRplhBx5rozmspb5gUKeVkuIKDJD08xKaywxOAM6YFsLlQWNKbKx8jUa/uDw==","signature_status":"signed_v1","signed_at":"2026-06-23T01:13:08.971610Z","signed_message":"canonical_sha256_bytes"},"source_id":"2606.21398","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6b168203235568eb5b2de35a42be59a5a6b71a245d4f3375e2deb5df4ec4117b","sha256:05621b59549ff04c0da52f84081d118f16808a541f0249c0585d178d69e518be"],"state_sha256":"466bec814bbbeccbda9b3837dc3091f848cfc271ae11c12ac54742691eda32b0"}
