The last layer of the decoders is typically a bilinear upsampling procedure to recover the final pixel-wise prediction. We empirically show that this oversimple and data-independent bilinear upsampling may lead to sub-optimal results.\n  In this work, we propose a data-dependent upsampling (DUpsampling) to replace bilinear, which takes advantages of the redundancy in the label space of semantic segmentation and is able to recover the pixel-wise prediction from lo","authors_text":"Chunhua Shen, Tong He, Youliang Yan, Zhi Tian","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2019-03-05T23:59:41Z","title":"Decoders Matter for Semantic Segmentation: Data-Dependent Decoding Enables Flexible Feature Aggregation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1903.02120","kind":"arxiv","version":3},"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":"sha256:02f388a47a3acb900efaf62b9a1b7b1a36a22e64318c8e87c8adfd0c1636ceb9","target":"record","created_at":"2026-05-17T23:49:21Z","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":"47d803791036b47135d74187fd44603b9837e957e3db1d37d30166ea9e126d04","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CV","submitted_at":"2019-03-05T23:59:41Z","title_canon_sha256":"398e20d517c38f2d9062a9ab8d0b296bb8afbeb522c13f9807c103270fa0c71b"},"schema_version":"1.0","source":{"id":"1903.02120","kind":"arxiv","version":3}},"canonical_sha256":"26ae357b29268459541bb8e6d6d6f27607a929dea1007778cd9672c643961ff1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"26ae357b29268459541bb8e6d6d6f27607a929dea1007778cd9672c643961ff1","first_computed_at":"2026-05-17T23:49:21.807868Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:49:21.807868Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"NNiZ/O1AEAji0WjUm+j2xMY9bSA8rtsZt+tfbfwHDnS6YBdVgVsUPZimrSo5mibL9k3LbPlvntHx9uaywmxVBw==","signature_status":"signed_v1","signed_at":"2026-05-17T23:49:21.808389Z","signed_message":"canonical_sha256_bytes"},"source_id":"1903.02120","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:02f388a47a3acb900efaf62b9a1b7b1a36a22e64318c8e87c8adfd0c1636ceb9","sha256:7c0c932cf1f63ab477bdaa662d39efa9577ceb9d6eac66c9b23cfbc888b48c16"],"state_sha256":"60530afee3e3b66b7a6a8192dbd1fabdbd5af9db21989788c8fdb1230d88da0c"}
