In exemplar-free class-incremental learning (EFCIL), this challenge is amplified because past data cannot be stored, making representation drift for old classes particularly harmful. Prototype-based EFCIL is attractive for its efficiency, yet prototypes drift as the embedding space evolves; therefore, projection-based drift compensation has become a popular remedy. We show, however, that existing one-directional projections introduce systematic bias: they either retroactively distort the current featu","authors_text":"Bartosz Krawczyk, Hongye Xu","cross_cats":["cs.CV"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2026-06-04T03:57:33Z","title":"Two-Way Is Better Than One: Bidirectional Alignment with Cycle Consistency for Exemplar-Free Class-Incremental Learning"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2606.05675","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":"sha256:88b5fc3934d754f42654a95a56bf1a96269496742ddd2be29ebb75912256205a","target":"record","created_at":"2026-06-05T01:14:58Z","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":"7de5585ea67e780b513e2f0ae8f33b53c9b4db9cc989937b738bd01e82a60ef8","cross_cats_sorted":["cs.CV"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2026-06-04T03:57:33Z","title_canon_sha256":"1125be43b1e5d842fa64e78b8b436f42768b909ccb02ce406d1af1a7f97b0b89"},"schema_version":"1.0","source":{"id":"2606.05675","kind":"arxiv","version":1}},"canonical_sha256":"971c7aa8bdf40575ed1a8cf7e601e4aa2af7a010817ac9f7491aa09354f46335","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"971c7aa8bdf40575ed1a8cf7e601e4aa2af7a010817ac9f7491aa09354f46335","first_computed_at":"2026-06-05T01:14:58.921153Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-05T01:14:58.921153Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"CLwapab/xhbAPt/Ii7cpWq4AfsdzMWERhR6FsJnaefO/QPSW08uIg0G/0mrn21WHjuewrAhk2LCWwpzXdivvCw==","signature_status":"signed_v1","signed_at":"2026-06-05T01:14:58.921600Z","signed_message":"canonical_sha256_bytes"},"source_id":"2606.05675","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:88b5fc3934d754f42654a95a56bf1a96269496742ddd2be29ebb75912256205a","sha256:67468fabd2a56a4472ad103ba1710a27e65de77a3d03a3a334dcfbb2dba6119e"],"state_sha256":"f6f0b24939baefa28a2f349454d984c72a77827a23392ead4867adf398955643"}
