Pick-Object-Attack: Type-Specific Adversarial Attack for Object Detection

1 code implementation5 Jun 2020 Omid Mohamad Nezami, Akshay Chaturvedi, Mark Dras, Utpal Garain

We specifically aim to attack the widely used Faster R-CNN by changing the predicted label for a particular object in an image: where prior work has targeted one specific object (a stop sign), we generalise to arbitrary objects, with the key challenge being the need to change the labels of all bounding boxes for all instances of that object type.

Analyzing Semantic Faithfulness of Language Models via Input Intervention on Question Answering

1 code implementation21 Dec 2022 Akshay Chaturvedi, Swarnadeep Bhar, Soumadeep Saha, Utpal Garain, Nicholas Asher

While transformer models achieve high performance on standard question answering tasks, we show that they fail to be semantically faithful once we perform these interventions for a significant number of cases (~50% for deletion intervention, and ~20% drop in accuracy for negation intervention).
