BiasBusters: Uncovering and Mitigating Tool Selection Bias in Large Language Models

ICLR 2026poster

Agents backed by large language models (LLMs) often rely on external tools drawn from marketplaces where multiple providers offer functionally equivalent options. This raises a critical point concerning fairness: if selection is systematically biased, it can degrade user experience and distort compe…

Adaptive Token Sampling for Efficient Vision Transformers

ECCV 2022poster

"While state-of-the-art vision transformer models achieve promising results in image classification, they are computationally expensive and require many GFLOPs. Although the GFLOPs of a vision transformer can be decreased by reducing the number of tokens in the network, there is no setting that is o…

Cross-Modal Spectrum Transformation Network for Acoustic Scene Classification

ICASSP 2021accepted

Convolutional neural networks (CNNs) with log-mel spectrum features have shown promising results for acoustic scene classification tasks. However, the performance of these CNN based classifiers is still lacking as they do not generalise well for unknown environments. To address this issue, we introd…

Semantic octree: Unifying recognition, reconstruction and representation via an octree constrained higher order MRF

ICRA 2015poster

On the one hand, mainly within the computer vision community, multi-resolution image labelling problems with pixel, super-pixel and object levels, have made great progress towards the modelling of holistic scene understanding. On the other hand, mainly within the robotics and graphics communities, m…
