We introduce Contrastive Inverse Reinforcement Learning (CIRL), a self-supervised framework for pre-training zero-shot imitation agents. Our methods rests on a key observation that many useful tasks can be summarized by a single goal state. We can thus convert the multi-task inverse RL problem into a more tractable goal-inference problem, and utilize state-of-the-art goal-conditioned RL methods to recover a policy t","authors_text":"Benjamin Eysenbach, Chongyi Zheng, Kathryn Wantlin","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2025-10-20T00:28:03Z","title":"Consistent Zero-Shot Imitation with Contrastive Goal Inference"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2510.17059","kind":"arxiv","version":2},"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":"sha256:64863bdfce0a1a56bb6e886224d69eb67a8ad7c5d7ceec0a45ada0895184f74d","target":"record","created_at":"2026-06-25T01:17:47Z","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":"d8b3ba9bbf6aa211186836d2e7e236215a686a12a55e02112887f417661c924c","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.LG","submitted_at":"2025-10-20T00:28:03Z","title_canon_sha256":"27a1e6c4be930e9b075cdb878fe3eeb81df8366c77af2864b2b65d5902d78001"},"schema_version":"1.0","source":{"id":"2510.17059","kind":"arxiv","version":2}},"canonical_sha256":"dfb926e648f45e29649690e510056a8d266e07a1f9e046a8191619873c1faa7a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"dfb926e648f45e29649690e510056a8d266e07a1f9e046a8191619873c1faa7a","first_computed_at":"2026-06-25T01:17:47.000150Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-25T01:17:47.000150Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"DhCDSBew4rMYQfvo1oMqXNRYzdEXpKgCDqwefOYm5M8n21iVofumZnlIijT7rUPO5cE683/+Xs1hZe4ss9oLAg==","signature_status":"signed_v1","signed_at":"2026-06-25T01:17:47.000607Z","signed_message":"canonical_sha256_bytes"},"source_id":"2510.17059","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:64863bdfce0a1a56bb6e886224d69eb67a8ad7c5d7ceec0a45ada0895184f74d","sha256:f095bc5371c54487a88fd6c6bb4aa31672d9c1ffd90c9b4d53d8a2eda6a82628"],"state_sha256":"0dc0189655d94b62ff0cd3e0c404c7f5f0c5914912dfb2cb6c3735c2d6fd0c2a"}
