Bias/Variance is not the same as Approximation/Estimation
Gavin Brown, Riccardo Ali
Published in TMLR, 2024
We establish a formal connection between the two seminal decompositions using ideas from statistical learning theory and information geometry.
Metric Learning for Clifford Group Equivariant Neural Networks
Riccardo Ali*, Paulina Kulytė*, Haitz Sáez de Ocáriz Borde, Pietro Liò
Published in ICML GRaM, 2024
We propose a metric learning scheme to enhance Clifford Group Equivariant Neural Networks, motivated using insights from category theory to guarantee its soundness.
Entropy-Lens: The Information Signature of Transformer Computations
Riccardo Ali*, Francesco Caso*, Christopher Irwin*, Pietro Liò
Published in arXiv, 2025
We track the Shannon entropy of intermediate predictions in transformers and use them to uncover consistent computational patterns.
Parameter-free approximate equivariance for tasks with finite group symmetry
Riccardo Ali, Pietro Liò, Jamie Vicary
Published in arXiv, 2025
We use techniques from representation theory to uncover what structure neural networks tend to learn, finding a strong preference for the regular representation. Building on this insight, we propose a simple method to enforce approximate equivariance with strong experimental results.
