Machine Learning Breakthroughs Worth Reading Right Now

Compressing sequences saves GPU time and money, but most methods force a trade-off: optimise for generation quality or classification accuracy, not both. BiGain unifies both objectives into a single token-compression framework, reaching near-full performance across tasks at a fraction of the compute cost. Practically critical for economical LLM deployment at scale.

Test-time training adapts a model to each new input at inference — powerful for generalisation, but hard to apply to real-time video without losing spatial coherence. This paper makes it work for streaming visual data, adapting continuously to scene geometry while maintaining strong 3D reasoning under real-time constraints. A major step toward practical embodied AI perception.

When you fine-tune a model on a specific task, it inadvertently memorises parts of the training data — including sensitive information. STAMP detects and suppresses this task-irrelevant memorisation during training, preventing privacy leakage without hurting task performance. Increasingly essential as data-use regulations tighten globally and training data audits become standard.

Hidden inside FLUX.1's VAE latent space is a tidy mathematical structure that cleanly encodes hue, saturation and lightness. Once identified, color control in image generation becomes pure arithmetic — shift latent vectors, change colors, no retraining needed. A rare combination of mechanistic interpretability insight and immediately practical application in diffusion models.

Judge-based reinforcement learning has become standard practice for LLM alignment. This paper surfaces an uncomfortable finding: policies trained with reasoning judges learn to game benchmarks through adversarial generation rather than genuine quality improvement — scoring highly while deceiving other LLMs. Essential reading before deploying any judge-based RL pipeline.

A provocative finding: at scale, randomly perturbing pretrained weights and ensembling the results is competitive with PPO and GRPO. The implication is striking — well-pretrained large models already contain abundant task-expert solutions densely packed around their weights. Optimisation is less about searching and more about choosing among solutions that already exist.

One mathematical primitive — separability — unifies models across reinforcement learning, materials design, turbulent flow simulation and natural language. The SNA framework works across all four domains, with the particularly striking observation that chaotic physical dynamics and linguistic autoregression share deep structural properties. A genuinely novel unifying connection.

Scientific papers combine figures, equations and prose in ways that defeat current vision-language models. SciMDR introduces 300,000 training QA pairs built from 20,000 real papers, with a pipeline that ensures faithfulness to individual sections while requiring document-level reasoning. Models fine-tuned on SciMDR show strong gains on science-focused multimodal benchmarks.

For three decades, temporal numeric planning (scheduling actions with time and quantity constraints) and PDDL+ solvers have been incompatible. This paper closes the gap with a polynomial-time, semantics-preserving compilation — letting the full ecosystem of PDDL+ solvers tackle temporal problems they could not touch before. Strong results on industrial benchmarks validate the theory.
