Before revision:  Our method achieves state-of-the-art performance on HACS Segments and THUMOS14 and competitive performance on  ActivityNet-1.3.
After revision:  Our method achieves state-of-the-art performance on HACS Segments (+3.35\% average mAP). As a single-network detector, TadTR runs 10\times faster than its comparable competitor. It outperforms existing single-network detectors by a large margin on THUMOS14 and competitive performance on ActivityNet-1.3.
