That is, we do severe damage to data and encourage a network to recover them. First, we complicate each of three powerful self-supervised task candidates: jigsaw puzzle, inpainting, and colorization. In addition, we introduce a novel complicated self-supervised task called \"Completing damaged jigsaw puzzles\" which is puzzles with one piece missing and the other pieces without color. We train a convolutional neural network not only to solve the puzzles, but also generate the missing content and ","authors_text":"Dahun Kim, Donggeun Yoo, Donghyeon Cho, In So Kweon","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2018-02-06T10:42:28Z","title":"Learning Image Representations by Completing Damaged Jigsaw Puzzles"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1802.01880","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":"sha256:9cb087159c6ebbe9a9deabef514db7c16b60eba4725bf9614de49a79d013e6bc","target":"record","created_at":"2026-05-18T00:24:21Z","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":"61c0637b6480366db4da4a3408916c1b493ab6f9fdcb7990261987d8c8148e8e","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2018-02-06T10:42:28Z","title_canon_sha256":"30818cfb0ca520e769d85b2cac34a5f6fad288307e7df23b02d39f5e99bf017f"},"schema_version":"1.0","source":{"id":"1802.01880","kind":"arxiv","version":1}},"canonical_sha256":"f6560e587c6e890d6f464a3c75b37708cc7ef965a44b6a47276ffd9d73600cc9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f6560e587c6e890d6f464a3c75b37708cc7ef965a44b6a47276ffd9d73600cc9","first_computed_at":"2026-05-18T00:24:21.029452Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:24:21.029452Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"/2BkzjScFDJOiy71LPd68EWXA0KrgIHglTyhqECgAfp7hNaqGT35SbQ6NnocpdBSrGuZdSjud+z1cmAhX8zYCQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:24:21.030054Z","signed_message":"canonical_sha256_bytes"},"source_id":"1802.01880","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9cb087159c6ebbe9a9deabef514db7c16b60eba4725bf9614de49a79d013e6bc","sha256:2dc71aea1a252da9ebf88d17bd9259d432ddac381ba70844ede767100dfdeec5"],"state_sha256":"91338918a9e71fdceb2c3fa70321233d3a9f1fd9d4c10d859959aed3ec037e42"}
