Focal loss for dense object detection github. CVPR 2017 Lin, T. The D-FINE-seg framework provides capabilities for training (on custom datasets), benchmarking, exporting, and running inference with object detection and instance segmentation models. IEEE International Conference on Computer Vision (ICCV), 2017. The classification is usually optimized by Focal Loss and the box location is commonly learned under Dirac delta distribution. BASNet introduced boundary-aware refinement with hybrid loss functions for precise object segmentation, while subsequent work explored efficient edge-refinement strategies. In contrast, one-stage detectors that are applied over a regular, dense sampling of possible object locations have the potential to be faster and simpler, but have trailed the accuracy of two-stage detectors thus far Huang, G.

Contribute to unsky/focal-loss development by creating an account on GitHub. Focal loss for Dense Object Detection. Introduction One-stage detector basically formulates object detection as dense classification and localization (i. 5 days ago · At the classification level, we introduce an Adaptive Class-Balanced Focal Loss that operationalizes margin theory under imbalance, enforcing larger margins for minority classes while dynamically . Jul 23, 2018 · The highest accuracy object detectors to date are based on a two-stage approach popularized by R-CNN, where a classifier is applied to a sparse set of candidate object locations. A PyTorch Implementation of Focal Loss. Y. et al. To demonstrate the effectiveness of the proposed focal loss, we design a simple one-stage object detector called RetinaNet, named for its dense sampling of object locations in an input image. 42nd Edition, Elsevier 1 day ago · Abstract Incremental Object Detection (IOD) aims to continuously learn new object classes without forgetting previously learned ones. PPG is a non-invasive and cost-effective biomedical signal that measures blood volume variations in peripheral circulation. Tsung-Yi Lin, Priya Goyal, Ross Girshick, Kaiming He, and Piotr Dollár. Focal Loss for Dense Object Detection. Generalized Focal Loss: Learning Qualified and Distributed Bounding Boxes for Dense Object Detection, NeurIPS2020 Focal loss for Dense Object Detection. , bounding box regression). (2020). While pseudo-labeling mitigates this in dense detectors, we identify a novel, distinct source of forgetting specific to DETR-like architectures 3 days ago · The multi-task loss composition (box + focal/detection + cosine embedding) enforces shared features while keeping objectives explicit. A persistent challenge is catastrophic forgetting, primarily attributed to background shift in conventional detectors. Trade-off: 1 day ago · Small object detection in remote sensing imagery remains challenging due to complex backgrounds, frequent occlusions, and dense distributions of objects, which often lead to suboptimal performance 🫀 Coronary Artery Disease Detection Using PPG Signals 📌 Project Overview This project presents a deep learning-based system for detecting Coronary Artery Disease (CAD) using Photoplethysmography (PPG) signals. e.
