In particular, a learned bi-causal coupling naturally serves as a simulator for generating joint sample paths that respect both prescribed marginal laws and the underlying information flow. Its practical use, however, is limited by the computational difficulty of enforcing bi-causal coupling constraints over path space, e","authors_text":"Haoyang Cao, Jesse Hoekstra, Renyuan Xu, Ruixun Zhang, Yumin Xu","cross_cats":["cs.LG"],"headline":"KL relaxation turns bi-causal optimal transport into a policy-gradient problem","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"math.OC","submitted_at":"2026-05-17T05:41:01Z","title":"Scalable Bi-causal Optimal Transport via KL Relaxation and Policy Gradients"},"references":{"count":23,"internal_anchors":0,"resolved_work":23,"sample":[{"cited_arxiv_id":"","doi":"","is_internal_anchor":false,"ref_index":1,"title":"Here, the first inequality follows fromJπ n+1 ≥V n+1 and the monotonicity of operatorQπ n+1, and the last inequality follows from (15)","work_id":"95dd3457-e2d9-4af2-b89c-d36057606821","year":null},{"cited_arxiv_id":"","doi":"","is_internal_anchor":false,"ref_index":2,"title":"NX n=0 cn(Yn, Y ′ n) # =E π","work_id":"92e2157a-694f-45d2-9eac-bed3823b4161","year":null},{"cited_arxiv_id":"","doi":"","is_internal_anchor":false,"ref_index":3,"title":"43 The definition ofWbc in (5) as the infimum overπ∈ΠΠΠbc yieldsW bc(µ, µ′)≥inf π0∈Π(µ0,µ′ 0) Eπ0[V0]","work_id":"c18fb885-1533-4079-8484-d7398c1e9c12","year":null},{"cited_arxiv_id":"","doi":"","is_internal_anchor":false,"ref_index":4,"title":"Notice that (A.3) holds for any initial coupling inΠ(µ0, µ′ 0)","work_id":"5b93d9f2-82ae-4ce9-ae32-b5e2e90bcdeb","year":null},{"cited_arxiv_id":"","doi":"","is_internal_anchor":false,"ref_index":5,"title":"To establish the second equivalent representation, notice thatγ ϵ ∈ M bc(µ, µ′)⊂Π ΠΠbc and Wbc(µ, µ′) = inf π0∈Π(µ0,µ′","work_id":"64f761fb-aff7-4675-ac60-d1ad02cfc366","year":null}],"snapshot_sha256":"62ca0d2ec3fc558ce01777bcf5f3d855e632f47dc06d0e8c47267ec71f3bb2bd"},"source":{"id":"2605.17271","kind":"arxiv","version":1},"verdict":{"created_at":"2026-05-19T23:06:42.062019Z","id":"a35e1a80-85ed-45cb-9e7b-cbefb76d5d55","model_set":{"reader":"grok-4.3"},"one_line_summary":"A KL-relaxed formulation of bi-causal optimal transport is solved via policy gradients with proven convergence to the original problem and nonasymptotic regret guarantees for the resulting algorithm.","pipeline_version":"pith-pipeline@v0.9.0","pith_extraction_headline":"KL relaxation turns bi-causal optimal transport into a policy-gradient problem","strongest_claim":"We establish dynamic programming principles for both the original and relaxed formulations, prove that the relaxed problem converges to the original bi-causal OT problem as the penalty grows, and derive explicit policy-gradient representations for the relaxed objective.
