Beyond Hungarian: Match-Free Supervision for End-to-End Object Detection
This paper introduces a novel match-free training scheme for DETR-based detectors, eliminating the computational overhead and complex training dynamics associated with the Hungarian algorithm. Our Cross-Attention-based Query Selection (CAQS) module utilizes encoded ground-truth information to probe decoder queries via cross-attention. This differentiable approach autonomously learns implicit correspondences, leading to a significant enhancement in training efficiency (over 50% reduction in matching latency) and superior performance, especially for large-scale objects, by bypassing discrete matching bottlenecks.

Introduction to Match-Free DETR
The paper proposes a novel match-free training scheme for DETR-based detectors, addressing the computational overhead and training complexities of the Hungarian algorithm. This paradigm shift offers significant advantages in efficiency and scalability for end-to-end object detection, particularly for large-scale objects.
Cross-Attention Query Selection
At the core of the approach is the Cross-Attention-based Query Selection (CAQS) module, which utilizes encoded ground-truth information as probes to interact with decoder queries. This allows the model to autonomously learn implicit correspondences through a continuous optimization process, replacing discrete assignments with differentiable correspondence learning.
Performance & Efficiency Gains
Experimental results demonstrate a significant enhancement in training efficiency, reducing matching latency by over 50%. The method achieves superior performance, particularly a +4.2 APL gain for large-scale objects and an overall +0.7 AP improvement, validating the effectiveness of the matching-free approach.
