We present the first principled way to find such shortest training sequences. Our key insight is to formulate sequential machine teaching as a time-optimal control problem. This allows us to solve sequential teaching by leveraging key theoretical and computational tools developed over the past 60 years in the optimal control community. Specifically, we study the Pontryagin Maximum Principle, which yields a necessa","authors_text":"Laurent Lessard, Xiaojin Zhu, Xuezhou Zhang","cross_cats":["cs.SY","math.OC","stat.ML"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2018-10-15T04:18:39Z","title":"An Optimal Control Approach to Sequential Machine Teaching"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1810.06175","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:fb56b79f3a1c510fa866621d72e6d823bd2f31c2161ac1e8e2ec6ac65cf53c2c","target":"record","created_at":"2026-05-18T00:03:14Z","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":"7fc1e2d0f2edbb2eafc3a9976f6830e3bc9eb82fb3b507261bafb2e5d1987a87","cross_cats_sorted":["cs.SY","math.OC","stat.ML"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2018-10-15T04:18:39Z","title_canon_sha256":"e5577f2b0adf51cdeeb1baa278b413bf47ba92d4e02062b945594bcf0484d48b"},"schema_version":"1.0","source":{"id":"1810.06175","kind":"arxiv","version":2}},"canonical_sha256":"a3d664abc985f8a535ea7ac57ff6c226a87a5ba6738ca7aa11235cfffc895f4c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a3d664abc985f8a535ea7ac57ff6c226a87a5ba6738ca7aa11235cfffc895f4c","first_computed_at":"2026-05-18T00:03:14.338055Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:03:14.338055Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"AJvFMBug8JKYBHFg/hGLkaSTytEtBhHyU4ctWaLgbDriiCnFhA95NKnVz2Qm+Gj3mE5cFkhhA6jSqep9pEWdCg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:03:14.338564Z","signed_message":"canonical_sha256_bytes"},"source_id":"1810.06175","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:fb56b79f3a1c510fa866621d72e6d823bd2f31c2161ac1e8e2ec6ac65cf53c2c","sha256:e5d22502b014233c8d885f7447bb5c88411d468b3167094061be01f9467265da"],"state_sha256":"4d8ed70ed7200002944c0bfb4a40887d452ce6511d2b05199820edb845584fa3"}
