XMedFusion: A Knowledge-Guided Multimodal Perception and Reasoning Framework for Autonomous Medical Systems

Hamza Riaz, Arham Haroon, Maha Baig, Muhammad Dawood Rizwan et autres

Autonomous medical and robotic systems increasingly rely on intelligent perception and reasoning capabilities to interpret visual data and support clinical decision making. Radiology report generation represents a critical component of such automated diagnostic workflows, yet existing end-to-end multimodal models often suffer from …

The Effects of Grouped Structural Global Pruning of Vision Transformers on Domain Generalisation

Hamza Riaz, Alan F. Smeaton

With the growing sizes of AI models like large language models (LLMs) and vision transformers, deploying them on devices with limited computational resources is a significant challenge particularly when addressing domain generalisation (DG) tasks. This paper introduces a novel grouped structural pruning …

Resilience of Vision Transformers for Domain Generalisation in the Presence of Out-of-Distribution Noisy Images

Hamza Riaz, Alan F. Smeaton

Modern AI models excel in controlled settings but often fail in real-world scenarios where data distributions shift unpredictably - a challenge known as domain generalisation (DG). This paper tackles this limitation by rigorously evaluating vision tramsformers, specifically the BEIT architecture which is …

Domain Generalisation with Bidirectional Encoder Representations from Vision Transformers

Hamza Riaz, Alan F. Smeaton

Domain generalisation involves pooling knowledge from source domain(s) into a single model that can generalise to unseen target domain(s). Recent research in domain generalisation has faced challenges when using deep learning models as they interact with data distributions which differ from those …

Vision Based Machine Learning Algorithms for Out-of-Distribution Generalisation

Hamza Riaz, Alan F. Smeaton

There are many computer vision applications including object segmentation, classification, object detection, and reconstruction for which machine learning (ML) shows state-of-the-art performance. Nowadays, we can build ML tools for such applications with real-world accuracy. However, each tool works well within the domain …
