When it comes to predicting people’s preferences, it pays to consider “the power of three”

MIT researchers have advanced random utility models, a framework nearly a century old for predicting consumer preferences, by introducing what they call 'the power of three.' This upgrade enhances the accuracy and applicability of preference prediction across various domains, potentially impacting how businesses model consumer behavior and decision-making.

From Uniform to Learned Graph Priors: Diffusion for Structure Discovery

Researchers propose Diff-prior, a diffusion-based adaptive prior system that improves neural relational inference (NRI) methods for discovering interaction graphs from data. Rather than relying on oversimplified uniform priors that treat edges independently, the new approach uses learned denoising-style calibration to produce more reliable and decisive structural discoveries across multiple NRI architectures.

Quality Adaptive Angular Margin Learning for Respiratory Sound Classification

Researchers present QLung, a machine learning framework that uses quality-adaptive angular margin learning to improve respiratory sound classification. The approach achieves 2.46% performance improvement on the ICBHI dataset and demonstrates superior out-of-distribution generalization on the SPRSound dataset compared to existing methods.

Unstable Features, Reproducible Subspaces: Understanding Seed Dependence in Sparse Autoencoders

Researchers investigate feature stability in sparse autoencoders (SAEs), finding that unstable features across training runs concentrate in reproducible lower-rank subspaces rather than representing pure noise. Stable features carry most functional signal for reconstruction and prediction, while unstable features have minimal individual impact but reflect shared geometric structure that different seeds resolve differently.

Multi-Rate Mixture of Experts for Accelerating Liquid Neural Network Training

Researchers propose Multi-Rate Mixture-of-Experts (MR-MoE), a framework that enhances Liquid Neural Networks for time-series modeling by deploying multiple experts operating at different time scales with adaptive gating. The approach combines continuous-time dynamics, multi-scale decomposition, and attention mechanisms to outperform traditional RNNs and monolithic LNNs on complex multivariate time-series tasks.

DiffCold: A Diffusion-based Generative Model for Cold-Start Item Recommendation

DiffCold presents a diffusion-based generative model addressing the cold-start recommendation problem in collaborative filtering systems. The approach resolves the inherent performance trade-off between new and established items by using conditional diffusion to unify their embedding representations while preserving structural integrity.
