Researchers challenge the long-standing "neural independence" theory, showing that learning actually makes neurons more coordinated.

When most people hear "polymer," they think of plastics. In our group, polymerization is a way to line up identical molecules like beads on a string and let quantum mechanics take over. Put magnetic ...

Mayo Clinic researchers have identified a hidden "movement map" deep within the brain—a discovery that could help surgeons ...

More engineers are turning to reinforcement learning to incorporate adaptive and self-tuning control into industrial systems. It aims to strike a balance between traditional ...

A new computational method allows modern atomic models to learn from experimental thermodynamic data, according to a ...

According to DeepLearning.AI (@DeepLearningAI), a new course titled 'Fine-tuning and Reinforcement Learning for LLMs: Intro to Post-training' has been launched in partnership with AMD and taught by ...

What if the most profound leap toward Artificial General Intelligence (AGI) wasn’t a headline-grabbing announcement, but a quiet breakthrough flying under the radar? Enter Grok 5, a development that ...

Researchers at Nvidia have developed a new technique that flips the script on how large language models (LLMs) learn to reason. The method, called reinforcement learning pre-training (RLP), integrates ...

Abstract: Accurately imaging the spatial distribution of longitudinal speed of sound (SoS) has a profound impact on image quality and the diagnostic value of ultrasound. Knowledge of SoS distribution ...

Large language models are typically refined after pretraining using either supervised fine-tuning (SFT) or reinforcement fine-tuning (RFT), each with distinct strengths and limitations. SFT is ...
