While it is well-known that ensemble methods improve prediction performance, and that combining accurate but diverse predictors helps, there is little knowledge on how to best promote & measure DNN diversity. We show that diversity can be cultivated by some unexpected means, such as model over-fitting or dropout variations. We also present details of our solution to the video understanding problem, which ranked #7 in the Kaggle competition (competing as the Yeti tea","authors_text":"Eng-Jon Ong, Mikel Bober-Irizar, Miroslaw Bober, Sameed Husain","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2017-07-13T18:11:02Z","title":"Cultivating DNN Diversity for Large Scale Video Labelling"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1707.04272","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:ecbd5a12c3a36a2a5fac3e720f26658c6df23fc37c07546a522dac3d5f5cfd3c","target":"record","created_at":"2026-05-18T00:40:18Z","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":"80db291bb10e2731c96cb15a721de361dcc07ce084a40b409f4f7a1fb5f0e9b4","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2017-07-13T18:11:02Z","title_canon_sha256":"f278f582ecd6edeef3eb70931cb48bcf2b5c90d88c2f76a9f81a44db512ce7b2"},"schema_version":"1.0","source":{"id":"1707.04272","kind":"arxiv","version":1}},"canonical_sha256":"eb8d47fe9a3730e2ad54e72a9fd4f479708fe09a857c7f14244fab55a85e7e9e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"eb8d47fe9a3730e2ad54e72a9fd4f479708fe09a857c7f14244fab55a85e7e9e","first_computed_at":"2026-05-18T00:40:18.826455Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:40:18.826455Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"+x5SajnSX39dkkU6+T0p54nTz7vtlitS7A8KCCjodt0M8fjYoVTOxhOW1ruj8MLTkmpEfc4lhSPsZWM2lO8sBg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:40:18.827139Z","signed_message":"canonical_sha256_bytes"},"source_id":"1707.04272","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ecbd5a12c3a36a2a5fac3e720f26658c6df23fc37c07546a522dac3d5f5cfd3c","sha256:15a5a02d362ec557f730e8b461840af9308c4ce8d91547a0fbb363a51ab1ea22"],"state_sha256":"19a05ecce0b86fa738de47e01141f82c2c4c1a69a36973ef454ff6a6b6a26ef1"}
