We formalize this interpretation by deriving a linear and space-variant structure of a convolutional network when its activations are fixed. We introduce general purpose algorithms to analyze a network and show its overall filter effect for each given location. We use this analysis to evaluate two types of image upscalers: deterministic upscalers that target the recovery of details from original content; and second, a new generation of upscalers th","authors_text":"Hanwen Liu, Pablo Navarrete Michelini","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2017-05-22T14:37:57Z","title":"Convolutional Networks with MuxOut Layers as Multi-rate Systems for Image Upscaling"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1705.07772","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:b7119fa0fc7276caf5004011a786382aaf8d29d29e916c1ad12f0c98b41ec8e8","target":"record","created_at":"2026-05-18T00:44:04Z","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":"2c9cf0c2cc718cfe8a199cde63d5205e0318d5c3761423dca96ba215cf45b8b6","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2017-05-22T14:37:57Z","title_canon_sha256":"e33a079cd4d35e4b5c2754f22d1e4c8a99d496f52111cb8dfdb6fc7710d0f321"},"schema_version":"1.0","source":{"id":"1705.07772","kind":"arxiv","version":1}},"canonical_sha256":"575514c47ea41ea235c8f80b67c1bea1042927017f197626a36310fb9142d9c6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"575514c47ea41ea235c8f80b67c1bea1042927017f197626a36310fb9142d9c6","first_computed_at":"2026-05-18T00:44:04.617300Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:44:04.617300Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"wluycG8Pu7Mz8skz6cgWf0DpU/xpWh5Vo0AJPXU3TOxzL0Jutgiw2TPe1ppvnSBW2EzqBXvfXJbHkr2iInhHAw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:44:04.617941Z","signed_message":"canonical_sha256_bytes"},"source_id":"1705.07772","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b7119fa0fc7276caf5004011a786382aaf8d29d29e916c1ad12f0c98b41ec8e8","sha256:2f955216d196d334d140706745e614dcffd876e47cdf528a9ddc4dea3dee49b3"],"state_sha256":"775fab9f696288d39d88b2b99782a9794e2a743c2111be5cae22558b06ffd90a"}
