NutriScreener: AI to screen child malnutrition from images

Malnutrition screening is often slow and hard to scale. NutriScreener is a new AI tool that flags undernutrition from children’s images and estimates key body measurements to support early intervention.

Blends visual cues with a curated knowledge base matched to a child’s age and region to improve fairness and accuracy.
Uses a multi-pose model that reads body cues across different angles and real-world conditions.
Clinician feedback: rated 4.3/5 for accuracy and 4.6/5 for efficiency in a clinical study.
Results: recall 0.79, AUC 0.82; significantly lower measurement errors than prior methods. Matching the knowledge base to demographics boosted recall by up to 25% and cut error by up to 3.5 cm.

Trained/tested on 2,141 children (AnthroVision) and evaluated across diverse populations (including ARAN and CampusPose), NutriScreener aims to scale early screening in low-resource settings so more kids get help sooner.

Responsible use matters: deployments should ensure consent, secure data handling, and local validation.

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
