By contrast, artificial neural networks trained with backpropagation generally have fixed connection weights that do not change once training is complete. While recent methods can endow neural networks with long-term memories, Hebbian plasticity is currently not amenable to gradient descent. Here we derive analytical expressions for activity gradients in neural networks with Hebbian plastic connections. Using these expressions, we can use backpropagation to train not just the basel","authors_text":"Thomas Miconi","cross_cats":["cs.AI","cs.LG","q-bio.NC"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.NE","submitted_at":"2016-09-08T00:02:20Z","title":"Learning to learn with backpropagation of Hebbian plasticity"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1609.02228","kind":"arxiv","version":2},"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":"sha256:7c19f39648a5608c3aa36961da7eed7d01378403bc52119b2694511f81956642","target":"record","created_at":"2026-05-18T01:01:51Z","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":"a5ee5904759a072f6d480818e2ed36ab64d2aee29241b0e71395952bef5ea4da","cross_cats_sorted":["cs.AI","cs.LG","q-bio.NC"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.NE","submitted_at":"2016-09-08T00:02:20Z","title_canon_sha256":"4c096f124da2dfe9d2616497763a57aa64829afd86914b6bcb6f54a25c3c6a93"},"schema_version":"1.0","source":{"id":"1609.02228","kind":"arxiv","version":2}},"canonical_sha256":"6c2e7190ebe88b687929081a3ec5366f82ea843b751f2b99c7bf6627ca8fd0b8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6c2e7190ebe88b687929081a3ec5366f82ea843b751f2b99c7bf6627ca8fd0b8","first_computed_at":"2026-05-18T01:01:51.448816Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:01:51.448816Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"k+nbnqyTINeiFZQvSr7yZkf4AFXtcURF5S7lRH5BgX1QqZu85szgKgvPlY4RbQ98Nhh6bA9kYBmQNpqEhsnABw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:01:51.449472Z","signed_message":"canonical_sha256_bytes"},"source_id":"1609.02228","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7c19f39648a5608c3aa36961da7eed7d01378403bc52119b2694511f81956642","sha256:727d711d42be7b1c276901bf1bf2e977d3aeb6a52f52e9794591e5765e76bdf4"],"state_sha256":"62809c91bc6ab59e7904c13321bb5d206dcff8fdfb9436d3c57ef77ab3be4cbc"}
