The rapid proliferation of artificial intelligence (AI) is transforming data centers into highly energy-intensive, industrial-scale systems characterized by extreme power density, volatile load profiles, and tightly coupled interactions between computing, cooling, and electrical subsystems. Global data center electricity consumption is projected to exceed 1,000 TWh annually by 2026, with AI workloads accounting for the dominant share of incremental demand. In this context, data center cooling has emerged as the largest controllable non-IT energy consumer, representing up to approximately […]

Manifold learning is a fundamental task at the core of data analysis and visualisation. It aims to capture the simple underlying structure of complex high-dimensional data by preserving pairwise dissimilarities in low-dimensional embeddings. Traditional methods rely on symmetric Riemannian geometry, thus forcing symmetric dissimilarities and embedding spaces, e.g. Euclidean. However, this discards in practice valuable asymmetric information inherent to the non-uniformity of data samples. We suggest to harness this asymmetry by switching to Finsler geometry, an asymmetric generalisation […]

arXiv:2603.12282v1 Announce Type: new Abstract: The rapid adoption of generative AI-powered search engines, such as ChatGPT, Perplexity, and Gemini, is fundamentally reshaping information retrieval. We are witnessing a critical shift from traditional ranked lists to synthesized, citation-backed answers. This paradigm shift challenges established Search Engine Optimization (SEO) practices and necessitates a new framework, termed Generative Engine Optimization (GEO). In highly regulated environments like the UK iGaming sector, visibility is no longer dictated by keyword density, but by an […]

Every few decades, computing changes its shape. Once again, we’ve arrived at that moment. But what form factor will it take? Which innovations will it require? In the first part of this series, I broke down the signals identifying AI-powered XR computing as the next major leap in tech. In Part II, I’ll look at why Big Tech can’t deliver this on its own — and why making this vision a reality requires rethinking the foundations of science, engineering, […]

arXiv:2601.02523v1 Announce Type: cross Abstract: Artificial intelligence has advanced rapidly through large neural networks trained on massive datasets using thousands of GPUs or TPUs. Such training can occupy entire data centers for weeks and requires enormous computational and energy resources. Yet the optimization algorithms behind these runs have not kept pace. Most large scale training still relies on synchronous methods, where workers must wait for the slowest device, wasting compute and amplifying the effects of hardware and network […]

Multi-vector representations generated by late interaction models, such as ColBERT, enable superior retrieval quality compared to single-vector representations in information retrieval applications. In multi-vector retrieval systems, both queries and documents are encoded using one embedding for each token, and similarity between queries and documents is measured by the MaxSim similarity measure. However, the improved recall of multi-vector retrieval comes at the expense of significantly increased latency. This necessitates designing efficient approximate nearest neighbor search (ANNS) algorithms for multi-vector […]

Motivation: Pathway enrichment analysis is widely used to interpret gene expression data. Standard approaches, such as GSEA, rely on predefined phenotypic labels and pairwise comparisons, which limits their applicability in unsupervised settings. Existing unsupervised extensions, including single-sample methods, provide pathway-level summaries but primarily capture linear relationships and do not explicitly model gene-pathway associations. More recently, deep learning models have been explored to capture non-linear transcriptomic structure. However, their interpretation has typically relied on generic explainable AI (XAI) techniques […]

We apply several machine learning algorithms to the problem of anomaly detection in operational data for large-scale, high-voltage electric power grids. We observe important differences in the performance of the algorithms. Neural networks typically outperform classical algorithms such as k-nearest neighbors and support vector machines, which we explain by the strong contextual nature of the anomalies. We show that unsupervised learning algorithm work remarkably well and that their predictions are robust against simultaneous, concurring anomalies.
