Given two groups of trajectories, the goal of this problem is to extract moving patterns in the form of sub-trajectories which are more similar to sub-trajectories of one group and less similar to those of the other. We propose a new method called Statistically Discriminative Sub-trajectory Mining (SDSM) for this problem. An advantage of the SDSM method is that the statistical significance of the extracted sub-trajectories are properly controlled in the sense that the probability of finding a false positive sub-trajectory is smaller","authors_text":"Hiroki Toda, Ichiro Takeuchi, Kazuya Nishi, Masayuki Karasuyama, Masayuki Sunaga, Taiju Ishiyama, Takuto Sakuma, Vo Nguyen Le Duy, Yasuo Tabei, Yuta Okubo","cross_cats":["cs.LG"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ML","submitted_at":"2019-05-06T02:05:07Z","title":"Statistically Discriminative Sub-trajectory Mining"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1905.01788","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":"sha256:46775a9fb3f6a576cc86886a414365b92dba6b9fc171a43dd3ca8c7dbf7fabc5","target":"record","created_at":"2026-05-17T23:46:57Z","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":"785f195ca8106bbec11a948fe2393b178066896925b52e9e379b58a0495d06b5","cross_cats_sorted":["cs.LG"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.ML","submitted_at":"2019-05-06T02:05:07Z","title_canon_sha256":"35722d40cd252492ef4774867e45d1ba17e85f0316b5ed916a03f7fe5d3836db"},"schema_version":"1.0","source":{"id":"1905.01788","kind":"arxiv","version":1}},"canonical_sha256":"26565e396660d4d617704f130d870031d39f8af4a3328bffe3894abfc1fa451d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"26565e396660d4d617704f130d870031d39f8af4a3328bffe3894abfc1fa451d","first_computed_at":"2026-05-17T23:46:57.412612Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:46:57.412612Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"brjTbpcC/FbUuvHW3DpKB2USPeVfKlsqT5g99Upg0AcMeJh2h5azrt1tzzVIlDGikgtkvr48AYKDDMjbBK9WDg==","signature_status":"signed_v1","signed_at":"2026-05-17T23:46:57.413304Z","signed_message":"canonical_sha256_bytes"},"source_id":"1905.01788","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:46775a9fb3f6a576cc86886a414365b92dba6b9fc171a43dd3ca8c7dbf7fabc5","sha256:b1387a160bde940e68dc43c1ed18d67d91622e5689aadebdf928bdd8f3b83ad8"],"state_sha256":"481b5f92b9b88ac6ded633cf82d908bac39762cffd1439790c3bc9bea8e45c18"}
