Asynchronous algorithms are often studied to solve optimization problems where the cost function takes the form $\\sum_{i=1}^M f_i(x)$, with a common assumption that each $f_i$ is sparse; that is, each $f_i$ acts only on a small number of components of $x\\in\\mathbb{R}^n$. Sparse recovery problems, such as compressed sensing, can be formulated as optimization problems, however, the cost functions $f_i$ are dense with respect to the components of $x$, and instead the signal $x$ is assumed to be s","authors_text":"Deanna Needell, Tina Woolf","cross_cats":["cs.DC"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2017-01-12T05:14:40Z","title":"An Asynchronous Parallel Approach to Sparse Recovery"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1701.03458","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:ffc9b484bdb6e7d20faac9e877616589efbc4a169f2529c7eef668cbb7dc4202","target":"record","created_at":"2026-05-18T00:52:54Z","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":"eed505f85974686f978c3675046d50977fdb613b064a98148cd2f394e530165c","cross_cats_sorted":["cs.DC"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.LG","submitted_at":"2017-01-12T05:14:40Z","title_canon_sha256":"236b788ffaafb9e32607c6cd4a27fae9d3b6a9ba0aae26e79c9c0db6add17e65"},"schema_version":"1.0","source":{"id":"1701.03458","kind":"arxiv","version":1}},"canonical_sha256":"65baa514ccca62e896a08f1dae321ecc61616753695f6f91a54508cb700f50d7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"65baa514ccca62e896a08f1dae321ecc61616753695f6f91a54508cb700f50d7","first_computed_at":"2026-05-18T00:52:54.760135Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:52:54.760135Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"z/SQW8ihiqMheYCaodftKUD0wleG0zjbttDNmlnL12JxOYdMkbfLm68dQN3fa5vkS5rcEXB2p+A4Dy4zhZm/DQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:52:54.760713Z","signed_message":"canonical_sha256_bytes"},"source_id":"1701.03458","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ffc9b484bdb6e7d20faac9e877616589efbc4a169f2529c7eef668cbb7dc4202","sha256:bc003c13c25b68c256af7ed905f5f43dbe344b5157d0657634910afb536272a5"],"state_sha256":"433c8520d601dc85ec29bee33389fac656e5153bec64c47796f406a0bb95fa67"}
