Smart Mics That Follow the Sound: On-Device AI for Clearer Audio

Ever wished your mic could zoom in on the right voice, even in a noisy room? This research shows how.

An on-device deep learning tracker works with a compact ring-shaped array of tiny MEMS microphones to steer a "listening beam" in real time—locking onto a moving target and turning down distractions.

Finds where a sound comes from in 3D using a single camera plus stereo depth cues.
Steers listening left-right and up-down via a concentric circular array.
Adapts as people move, boosting signal-to-interference for clearer speech.

Why it matters: cleaner calls, smarter home assistants, better robots, and more reliable assistive tech—even with multiple talkers.

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
