Teach Your AI Composer to Feel Tension

What if you could sketch a “tension curve” and have an AI compose music that follows it? That’s exactly what this study delivers.

Tonal tension—the ebb and flow of stability vs. suspense in harmony—drives how music feels. The authors plug a computational tension model into a Transformer and steer generation with a dual-level beam search:

Token level: re-ranks notes by model probability and diversity to keep quality high.
Bar level: re-ranks phrases to match your target tension over time.

In tests, the system reliably modulates tension to fit a desired curve, and listeners confirm the results. Bonus: it can produce multiple, distinct interpretations under the same tension setting—useful for film scoring, games, education, and creative exploration.

Beyond URLs: Metadata That Makes LLMs Train Faster

Smarter LLMs, Faster—thanks to metadata What if training a large language model didn't just rely on text, but on the context around it? This study shows that adding fine-grained metadata—not just URLs—can meaningfully speed up pretraining and improve quality. * Beyond URLs: detailed quality signals (e.

Escaping the Verifier: Learning to Reason via Demonstrations

LLMs can learn to reason—without task verifiers Many real-world problems don’t have automatic checkers to grade answers, even though we have lots of expert solutions. RARO (Relativistic Adversarial Reasoning Optimization) shows how to train reasoning skills from those examples alone. How it works: * A policy (the model) tries

VacuumVLA: A Two-in-One Robot Hand That Grips and Suctions

Robots guided by Vision-Language-Action (VLA) AI are getting better at everyday tasks—but most still use simple two-finger grippers. That limits them on smooth, flat, or handleless objects. VacuumVLA is a low-cost robot hand that merges a standard two-finger gripper with a vacuum suction cup. The robot can switch between

ChatDRex: No‑Code, Conversational AI for Drug Repurposing

Meet ChatDRex Finding new uses for approved drugs can save years and millions. But making those predictions usually takes teams of specialists and a tangle of tools. ChatDRex changes that. It’s a conversation-based, no‑code, multi‑agent system that lets clinicians and researchers ask complex bioinformatics questions in plain
