Clone detection is a fundamental branch of automatic source code comprehension, having many applications in refactoring recommendation, plagiarism detection, and code summarization. A particularly interesting case of clone detection is the detection of semantic clones, i.e., code snippets that have the same functionality but significantly differ in implementation. A promising approach to detecting semantic clones is contrastive learning (CL), a machine learning paradigm popular in computer vision but not yet commonly ","authors_text":"Egor Bogomolov, Egor Spirin, Maksim Zubkov, Timofey Bryksin","cross_cats":["cs.LG"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SE","submitted_at":"2022-06-17T12:25:44Z","title":"Evaluation of Contrastive Learning with Various Code Representations for Code Clone Detection"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2206.08726","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":"sha256:44c3439964c194c06685d768ea2d14ba0220035ed709260827201ae641d28f6f","target":"record","created_at":"2026-07-05T04:32:42Z","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":"e24c6768e6e0361eefc5aa579120cddd195715b7e9f12919950220e57af5fef1","cross_cats_sorted":["cs.LG"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SE","submitted_at":"2022-06-17T12:25:44Z","title_canon_sha256":"c4e805af5fe1d6abe80e3d4a2b89dd9d8cecd67f5d5541b8e19411230e3bdfda"},"schema_version":"1.0","source":{"id":"2206.08726","kind":"arxiv","version":1}},"canonical_sha256":"aab547bcda6c237cc8961fda5f3a399755d9d5ea8dcd7ae3877af1e486ba5b0f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"aab547bcda6c237cc8961fda5f3a399755d9d5ea8dcd7ae3877af1e486ba5b0f","first_computed_at":"2026-07-05T04:32:42.645115Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T04:32:42.645115Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"OlVVuODZ82fUwL12nMlKdNPwyz8bQJ1q80a9L9Pmxov+V6FHmagge9VTUlh8EF6h683drddXHqhCg3LZL3YPCw==","signature_status":"signed_v1","signed_at":"2026-07-05T04:32:42.645645Z","signed_message":"canonical_sha256_bytes"},"source_id":"2206.08726","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:44c3439964c194c06685d768ea2d14ba0220035ed709260827201ae641d28f6f","sha256:12ad1dcb9157c144c512226e6f96005bffe9674badf6d0296e10da5afe81e989"],"state_sha256":"ffb194b768dffc281da05b913a05643022a5bffea9c85198024f275ff7cf3813"}
