A specified number of discussion threads predicted to be popular are recommended, chosen from a fixed window of recent comments to track. Novel deep reinforcement learning architectures are studied for effective modeling of the value function associated with actions comprised of interdependent sub-actions. The proposed model, which represents dependence between sub-actions through a bi-directional LSTM, gives the best performance acr","authors_text":"Jianfeng Gao, Jianshu Chen, Ji He, Li Deng, Lihong Li, Mari Ostendorf, Xiaodong He","cross_cats":["cs.AI","cs.LG"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2016-06-12T05:38:20Z","title":"Deep Reinforcement Learning with a Combinatorial Action Space for Predicting Popular Reddit Threads"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1606.03667","kind":"arxiv","version":4},"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:f241864bb2848abb45cf04717b740a084b45b6330331b75e822fbff93e6502e2","target":"record","created_at":"2026-05-18T01:04:30Z","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":"be3b5fc0d53d268f35cd32f4d40e32e0e962dad976afa4a1ef8cb05e8b452fd6","cross_cats_sorted":["cs.AI","cs.LG"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2016-06-12T05:38:20Z","title_canon_sha256":"dbc175beda5026e52906da9a9c4818ca234c2e613695bb9e3cf46575f4a7eb40"},"schema_version":"1.0","source":{"id":"1606.03667","kind":"arxiv","version":4}},"canonical_sha256":"c186d628c2fc70265a7ea56c43e547af0c03dfc6d7b78f8d221b2061316b5687","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c186d628c2fc70265a7ea56c43e547af0c03dfc6d7b78f8d221b2061316b5687","first_computed_at":"2026-05-18T01:04:30.954123Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:04:30.954123Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"7Kya6Wi4omxdcQx1j081/nyW8BRRNa/s2X12Qdy+WalJl/N/CeNybWEYw/vGm0E6zWo5cRYZj+OlYPUhLSncCg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:04:30.954930Z","signed_message":"canonical_sha256_bytes"},"source_id":"1606.03667","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f241864bb2848abb45cf04717b740a084b45b6330331b75e822fbff93e6502e2","sha256:15a3c09882f6da8a0bafcaedc16443a1db4f3b22064c41c0849975922331b822"],"state_sha256":"f899e84554dc57462252e9bad666fe6e6304e20fcd3161da7706f76a454c339b"}
