Most of the labels in multi-label data sets are associated with a small number of training examples, much smaller compared to the size of the data set. Class imbalance poses a key challenge that plagues most multi-label learning methods. Ensemble of Classifier Chains (ECC), one of the most prominent multi-label learning methods, is no exception to this rule, as each of the binary models it builds is trained from all positive and negative examples of a label. To make ECC resilient to class imbalance, we first couple it with ran","authors_text":"Bin Liu, Grigorios Tsoumakas","cross_cats":["stat.ML"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2018-07-30T15:13:49Z","title":"Making Classifier Chains Resilient to Class Imbalance"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1807.11393","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:c38ab3b9bd55290b4e6af860324d243cfad6341032be341c6b52f3c1646bdf01","target":"record","created_at":"2026-05-18T00:01:28Z","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":"5590f3cbd4a0cb1ab18261bc33cd68ff7d4daa12327767406b0650e308fd9b23","cross_cats_sorted":["stat.ML"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2018-07-30T15:13:49Z","title_canon_sha256":"5c0d913c0a9eecd5eb16ba63c91641418ee762bfc0f3b3f845876f9910b8dac2"},"schema_version":"1.0","source":{"id":"1807.11393","kind":"arxiv","version":4}},"canonical_sha256":"4efab8208d9e29bb6da642809ece0414f818bdb20a837c66e7b7965f62f89b80","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4efab8208d9e29bb6da642809ece0414f818bdb20a837c66e7b7965f62f89b80","first_computed_at":"2026-05-18T00:01:28.939558Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:01:28.939558Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"0xcvh0Xqe0u6MCgFOoQCaJywiekW9UrTbEFTNPC/Y56yL1p0h148mm++YIfP1Vo9Evy5zwgJMhL7RzfWez5JBg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:01:28.939959Z","signed_message":"canonical_sha256_bytes"},"source_id":"1807.11393","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c38ab3b9bd55290b4e6af860324d243cfad6341032be341c6b52f3c1646bdf01","sha256:35e8ab3129c17d80e9d801d5f0958adeeeefa629782397346b663e9eb1e4ee0b"],"state_sha256":"fa94bc6514f50d4c98cc2ef3e78819060aa6cfcd641d2639889d3215195d47fc"}
