We consider a setting where each task is handled by a different machine, with samples for the task available locally on the machine, and study communication-efficient methods for exploiting the shared structure.","authors_text":"Jialei Wang, Mladen Kolar, Nathan Srebro","cross_cats":["stat.ML"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2016-03-07T18:11:54Z","title":"Distributed Multi-Task Learning with Shared Representation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1603.02185","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":"sha256:307b9968c395e47caa63cfd34a2ec455cf09e12b91ef0484d205e8ed24d0b5f4","target":"record","created_at":"2026-05-18T01:19:31Z","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":"02b713ab2b0fa75527d6d4dbb031e34bff729f018cea272248e7e406c98b0723","cross_cats_sorted":["stat.ML"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2016-03-07T18:11:54Z","title_canon_sha256":"f3264963be1002120eddbb393bd5f329b2f579c51671202290e13181ec0fcbc9"},"schema_version":"1.0","source":{"id":"1603.02185","kind":"arxiv","version":1}},"canonical_sha256":"27199f8abe25f4bc3720a6f1511c935cb210db9eec868ba2470de26ab9a33f68","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"27199f8abe25f4bc3720a6f1511c935cb210db9eec868ba2470de26ab9a33f68","first_computed_at":"2026-05-18T01:19:31.412570Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:19:31.412570Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"hkAMGBXYZ54VKnazDfb+CiISL4j+f/frPHaU4cDsAdGZEkAW0r+WYO8holUug7yJA+VPgjbh84cqohNLfrZeBw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:19:31.413020Z","signed_message":"canonical_sha256_bytes"},"source_id":"1603.02185","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:307b9968c395e47caa63cfd34a2ec455cf09e12b91ef0484d205e8ed24d0b5f4","sha256:bda54ad811b121fe40fa9eccdf6045099132a7fa56bda6da5ab6abb1a72b0f68"],"state_sha256":"8a1b722536b51cf6523ad39f41a8fe069eb59ac0f2dfd0400808adcf03e431a4"}
