sudoLLM: On Multi-role Alignment of Language Models
Soumadeep Saha, Akshay Chaturvedi, Joy Mahapatra +1
User authorization-based access privileges are a key feature in many safety-critical systems, but have not been extensively studied in the large language model (LLM) realm. In this…
Limits for Learning with Language Models
Nicholas Asher, Swarnadeep Bhar, Akshay Chaturvedi +2
With the advent of large language models (LLMs), the trend in NLP has been to train LLMs on vast amounts of data to solve diverse language understanding and generation tasks. The l…
Analyzing Semantic Faithfulness of Language Models via Input Intervention on Question Answering
Akshay Chaturvedi, Swarnadeep Bhar, Soumadeep Saha +2
Transformer-based language models have been shown to be highly effective for several NLP tasks. In this paper, we consider three transformer models, BERT, RoBERTa, and XLNet, in bo…
Pick-Object-Attack: Type-Specific Adversarial Attack for Object Detection
Omid Mohamad Nezami, Akshay Chaturvedi, Mark Dras +1
Many recent studies have shown that deep neural models are vulnerable to adversarial samples: images with imperceptible perturbations, for example, can fool image classifiers. In t…
Exploring the Robustness of NMT Systems to Nonsensical Inputs
Akshay Chaturvedi, Abijith KP, Utpal Garain
Neural machine translation (NMT) systems have been shown to give undesirable translation when a small change is made in the source sentence. In this paper, we study the behaviour o…
Mimic and Fool: A Task Agnostic Adversarial Attack
Akshay Chaturvedi, Utpal Garain
At present, adversarial attacks are designed in a task-specific fashion. However, for downstream computer vision tasks such as image captioning, image segmentation etc., the curren…
A Limitation of V-Matrix based Methods
Niharika Gauraha, Akshay Chaturvedi
To estimate the conditional probability functions based on the direct problem setting, V-matrix based method was proposed. We construct V-matrix based constrained quadratic program…
CapsDeMM: Capsule network for Detection of Munro's Microabscess in skin biopsy images
Anabik Pal, Akshay Chaturvedi, Utpal Garain +3
This paper presents an approach for automatic detection of Munro's Microabscess in stratum corneum (SC) of human skin biopsy in order to realize a machine assisted diagnosis of Pso…
