Smarter Reasoning, Less Compute: Teaching Models When to Stop

28.11.2025 by qfx

This work introduces a latent reasoning architecture-distinct from conventional Chain-of-Thought reasoning-that leverages specialized tokens, such as $START$ and $END$, within a recurrent filter to refine the reasoning process, though implementations may vary across different studies.

New research explores how reinforcement learning can optimize the reasoning process in large language models, leading to more efficient and effective problem-solving.

Predicting Alzheimer’s Before Symptoms Appear

28.11.2025 by qfx

The methodology predicts the progression of Alzheimer’s disease by generating plausible future brain image sequences from past observations, effectively reconstructing missing data through interpolation and then extrapolating forward in time to forecast subsequent brain states.

A new deep learning approach uses the brain’s own structural changes over time to forecast the progression of Alzheimer’s disease, potentially enabling earlier diagnosis and intervention.
