Introduction to the 1st Place Winning Model of OpenImages Relationship Detection Challenge
[article]

arXiv

This article describes the model we built that achieved 1st place in the OpenImage Visual Relationship Detection Challenge on Kaggle. ...
We show in ablation study that each factor can improve the performance to a non-trivial extent, and the model reaches optimal when all of them are combined. ...
One major failure case of our model is on the predicate "hold", where the model usually needs to focus on the small area of the intersection of a human hand and the object, which our model is currently ...

Our model outperforms the winning method of the OpenImages Relationship Detection Challenge by 4.7\% (16.5\% relative) on the test set. ...
Most scene graph parsers use a two-stage pipeline to detect visual relationships: the first stage detects entities, and the second predicts the predicate for each entity pair using a softmax distribution ...
Our best model achieves 0.328 on the Private set of the OpenImages Relationship Detection Challenge, outperforming the winning model by a significant 4.7% (16.5% relative) margin. ...

This task is commonly seen as an extension to the object detection task where objects are detected individually, while the former requires recognizing relationships between object pairs. ...
In thesis we start with an inherent issue lying in scene graph parsing: the unbearable quadratic complexity of relationship detection. ...

The ultimate aim of this line of work is to build models capable of drawing connections between different modes of data, e.g., images+text. ...
To this end, we present algorithms that discover grounded image-text relationships from noisy, long documents, e.g., Wikipedia articles and the images they contain. ...
The top, middle, and bottom rows are sampled from the 99th, 50th, and 1st percentiles of model scores respectively. ...
