Standard approaches involve learning a policy over beliefs or observation-action histories. However, both of these have drawbacks; it is expensive to track the belief online, and it is hard to learn policies directly over histories. We propose a method for policy learning under partial observability called the Belief-Grounded Network (BGN) in which an auxiliary belief-reconstruction loss incentivizes a neural network to concisely su","authors_text":"Brett Daley, Christopher Amato, Hai Nguyen, Robert Platt, Xinchao Song","cross_cats":["cs.AI","cs.LG"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.RO","submitted_at":"2020-10-19T02:02:21Z","title":"Belief-Grounded Networks for Accelerated Robot Learning under Partial Observability"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2010.09170","kind":"arxiv","version":5},"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":"sha256:3bff196f20a4ed21794c4ee0b6ef470fa231215ae3219e1df6b71d04677405d7","target":"record","created_at":"2026-07-05T03:24:26Z","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":"09ffdbd077c9ff6a59cfdbefcc8ea7979095ee1e08dcaf03802c2de1317848ae","cross_cats_sorted":["cs.AI","cs.LG"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.RO","submitted_at":"2020-10-19T02:02:21Z","title_canon_sha256":"5650b61dc8e490b71d34a354d3ae9e6872212aee884cb16818a2e460d4d48a73"},"schema_version":"1.0","source":{"id":"2010.09170","kind":"arxiv","version":5}},"canonical_sha256":"9f1a0a6b871703694496f908ff70a5105808987d9a472e5276c575cbda02e816","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9f1a0a6b871703694496f908ff70a5105808987d9a472e5276c575cbda02e816","first_computed_at":"2026-07-05T03:24:26.838696Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T03:24:26.838696Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"QZ1SqOM3gjIgeztSCMSyIaC6QHzdIb6DtFK8Gj/8O6PAN4mugnHnZaurA65WwLRhHgHuFxDKEuqI8F8D8x+VDg==","signature_status":"signed_v1","signed_at":"2026-07-05T03:24:26.839169Z","signed_message":"canonical_sha256_bytes"},"source_id":"2010.09170","source_kind":"arxiv","source_version":5}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3bff196f20a4ed21794c4ee0b6ef470fa231215ae3219e1df6b71d04677405d7","sha256:979748701c30106fc44d4748269e4cefe7b9eb0f5bbd0dc5b950ccab5f9687b6"],"state_sha256":"681ef67cf962b87a42e688fd50bf530d5f821786938915f64ed417c7805bcd12"}
