... transformer models ... using learnable queries in place of region proposals has given rise to ... one-stage detection models ... have since dominated human-object interaction (HOI) detection.
... the success of such one-stage HOI detectors can ... be attributed to the representation power of transformers.
... discovered that when equipped with the same transformer, their two-stage counterparts can be more performant and memory-efficient, while taking a fraction of the time to train.
... propose the Unary-Pairwise Transformer, a two-stage detector that exploits unary and pairwise representations for HOIs.
... the unary and pairwise parts of ... transformer network specialise, with the former ... increasing the scores of positive examples and the latter decreasing the scores of negative examples.
... method ... significantly outperform state-of-the-art approaches. ... with ... real-time performance on a single GPU.
