Here the two sets of features are merged again to produce one shared set of offsets, which are small position shifts telling the detector where to sample. The aim is that each feature lines up with the prediction made from it, which would matter for more reliable detection of objects in images.","findings":["The head design reintegrates decoupled classification and regression features to provide shared offsets.","Anchor-based and anchor-free regression are used jointly to help find objects with large aspect ratios or occlusion from similar-sized objects.","On MS-COCO, MADet reaches 42.5% AP with a vanilla ResNet50 backbone, which the authors say surpasses multiple strong baselines."],"terms":[{"term":"decoupled classification and regression features","means":"Separate sets of internal image features used for deciding what an object is and for working out where its box lies."},{"term":"offsets","means":"Small position shifts that tell the detector where to sample features, so they better match the object being predicted."},{"term":"feature-prediction pairs","means":"Each image feature together with the prediction made from it, which should correspond to the same location."}],"basis":"abstract","abstractFrom":"europepmc","model":"claude-sonnet-5-5","writtenAt":"2026-10-24T21:01:41.110Z","version":"context/0.2"},"summary":{"status":"written","at":"2026-10-24T21:01:41.110Z","attempts":1,"model":"claude-sonnet-5-5","why":null},"note":"Machine-written context to help a reader: it is not evidence, it moves no number, and it may be wrong.
