@ahmedkar_ Thanks! And I agree. Pixel-level prediction has been incredibly useful, but it’s often a poor proxy for relevance. What we’re really after is structure that reflects influence on behaviour, not fidelity of reconstruction.

@IngmarPosner Love this, especially as a contrast to video prediction objectives. Optimising for exact pixel reconstruction is unrealistic yet that’s where much of current world model research still focuses. Brilliant work!

A recurring theme in our recent work (e.g. SPARTAN): predictive world models become more interpretable when they help identify which parts of the input stream actually influence behaviour. Learning what matters, not just what happens, is central. arxiv.org/pdf/2411.06890

Very excited to share our new work - SPARTAN: A Sparse Transformer Learning Local Causation. We develop a Transformer world model that learns local causal dependencies between entities, leading to improved adaptation efficiency and robustness with accurate prediction. 🧵

On my way to the 7th UK Manipulation W/s - a great way to start 2026! Over the years it’s become a premier UK meeting place for exchanging ideas across planning, control, and learning in robot manipulation. If you’re attending, do come say hello. robot-manipulation.uk

Always look forward to CoRL - for the people, papers & workshops. Sadly have to miss it this year. Delighted that @junjungoal & Alex Mitchell are there representing A2I - and @JankowskiJulius is presenting new work from our Amazon team! 🎉 See you next year!

NVIDIA’s £2bn pledge to UK AI startups is recognition that we don’t just use AI: we invent it, shape it & apply it. As @UniofOxford researcher & co-founder of a successful AI startup, I was proud to be in the room. #AI #UKTech

Amongst my favourite research directions this year: understanding model complexity and its link to generalization and intelligence. Progress here could mean leaner models, versatile representations, and less reliance on data/energy. Excited that we’re off to the races on this!
Branton DeMoss@BrantonDeMoss

I’m pleased to announce our work which studies complexity phase transitions in neural networks! We track the Kolmogorov complexity of networks as they “grok”, and find a characteristic rise and fall of complexity, corresponding to memorization followed by generalization. 🧵

How can a transformer uncover local causal dependencies in dynamic systems, from simulations to real-world data? 🤔 The answer: Hard attention + sparsity. But with a twist. Meet SPARTAN: More causal. More efficient. Just as accurate. #Robotics #ML #AI #CausalAI

On my way to #ICRA2024. Looking forward to Japan! Looking forward to seeing old friends and making new ones! And looking forward to presenting some of the work from @a2i_oxford and collaborators in Yokohama with @Jack_T_Collins, @junjungoal and @jannikzuern
Oxford Applied AI Lab@a2i_oxford

Delighted to be at #ICRA2024. Interested in effective sim-2-real transfer for world models (WeBT7-CC.6)? Or benchmarking for robot assembly (ThAT9-CC.3)? Or predicting lane graphs for autonomous driving (ThBT6-CC.2)? Come and see us to meet, discuss, or just hang-out...

Trajectory optimisation in high dimensional spaces is notoriously hard. What if you could leverage basic experience of what the system can do and let a diffusion model and vanilla sim guide you? Stunning work led by @junjungoal with @ShaohongZhong and @Jack_T_Collins @a2i_oxford
Jun Yamada@junjungoal

We introduce D-Cubed, a novel trajectory optimisation method using a latent diffusion model trained from a task-agnostic play dataset, including only representative hand motions, to solve dexterous deformable object manipulation tasks! (1/N)
