The options framework provided clues to temporal abstraction in the RL, and the option-critic architecture elegantly solved the two problems of finding options and learning RL agents in an end-to-end manner. However, it is necessary to examine whether the options learned through this method play a mutually exclusive role. In this paper, we propose a Hellinger distance regularizer, a method for disentangling options. In addition, we will shed light on various indicators from the statistical ","authors_text":"Junyoung Choi, Minsung Hyun, Nojun Kwak","cross_cats":["stat.ML"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2019-04-15T07:43:17Z","title":"Disentangling Options with Hellinger Distance Regularizer"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1904.06887","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:ef6baf1dc19bae2b6fa079dcb30e464182639780b315d39fe8bbcb989452bb13","target":"record","created_at":"2026-05-17T23:48:35Z","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":"d012fe6d49722191ce48dca459f2003e27a03adec43d1ef3d9c515c98367de02","cross_cats_sorted":["stat.ML"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2019-04-15T07:43:17Z","title_canon_sha256":"6037b464e350ede05f4e86006cab22ba044f827359b7b8fe4cd10130d2436bd7"},"schema_version":"1.0","source":{"id":"1904.06887","kind":"arxiv","version":1}},"canonical_sha256":"8a99f9d098b0e1a199e608a05b4a80ecd886f14f8a8561bd750b4f6ab5aac8c9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8a99f9d098b0e1a199e608a05b4a80ecd886f14f8a8561bd750b4f6ab5aac8c9","first_computed_at":"2026-05-17T23:48:35.885755Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:48:35.885755Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"EG+6af3xCI/FrlNFVQ/TgWeiwQV9fG5J887MUK1fvwmw4I5xvWWXdk4dLxFhMY/Iv3BhKDqh2wEqNxUzLgXTBA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:48:35.886436Z","signed_message":"canonical_sha256_bytes"},"source_id":"1904.06887","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ef6baf1dc19bae2b6fa079dcb30e464182639780b315d39fe8bbcb989452bb13","sha256:6e6bf0abcaa0b802a7f4fdb71370c7d6974464e33ecdb0d69246ec7da80edf4e"],"state_sha256":"c11038709d01030b9648392b26963e94bb2b8bed72304a5591aa678771471e88"}
