Here are my favourites from the National Portrait Gallery's Portrait Award 2025. It's a fantastic selection this year, and free to see as always.

Some of the African collection. This room was very exciting to me, much more vibrant and interesting than a bunch of old crumbling statues. A lot of this is contemporary art. Well chosen!

Room-acoustic simulations as an alternative to measurements for audio-algorithm evaluation
Audio-signal-processing and audio-machine-learning (ASP/AML) algorithms are ubiquitous in modern technology like smart devices, wearables, and entertainment systems. Development of such algorithms and models typically involves a formal evaluation to demonstrate their effectiveness and progress beyond the state-of-the-art. Ideally, a thorough evaluation should cover many diverse application scenarios and room-acoustic conditions. However, in practice, evaluation datasets are often limited in siz…

Privacy Risks in Time Series Forecasting: User- and Record-Level Membership Inference
Membership inference attacks (MIAs) aim to determine whether specific data were used to train a model. While extensively studied on classification models, their impact on time series forecasting remains largely unexplored. We address this gap by introducing two new attacks: (i) an adaptation of multivariate LiRA, a state-of-the-art MIA originally developed for classification models, to the time-series forecasting setting, and (ii) a novel end-to-end learning approach called Deep Time Series (DT…

Beyond fragmented dopant dynamics in quantum spin lattices: Robust localization and sub-diffusion
The motion of dopants in magnetic spin lattices has received tremendous attention for at least four decades due to its connection to high-temperature superconductivity. Despite these efforts, we lack a complete understanding of their behavior, especially out-of-equilibrium and at nonzero temperatures. In this Article, we take a significant step towards a much deeper understanding based on state-of-the-art matrix-product-state calculations. In particular, we investigate the non-equilibrium dynam…
