Researchers discover a shortcoming that makes LLMs less reliable

⋅

Large language models (LLMs) sometimes learn the wrong lessons, according to an MIT study. Rather than answering a query based on domain knowledge, an LLM could respond by leveraging grammatical patterns it learned during training. This can cause a model to fail unexpectedly when deployed on new tasks. The researchers found that models can mistakenly link certain sentence patterns to specific topics, so an LLM might give a convincing answer by recognizing familiar phrasing instead of understanding the […]

New control system teaches soft robots the art of staying safe

New control system teaches soft robots the art of staying safe

⋅

Imagine having a continuum soft robotic arm bend around a bunch of grapes or broccoli, adjusting its grip in real time as it lifts the object. Unlike traditional rigid robots that generally aim to avoid contact with the environment as much as possible and stay far away from humans for safety reasons, this arm senses subtle forces, stretching and flexing in ways that mimic more of the compliance of a human hand. Its every motion is calculated to […]

How to Build a Meta-Cognitive AI Agent That Dynamically Adjusts Its Own Reasoning Depth for Efficient Problem Solving

How to Build a Meta-Cognitive AI Agent That Dynamically Adjusts Its Own Reasoning Depth for Efficient Problem Solving

⋅

In this tutorial, we build an advanced meta-cognitive control agent that learns how to regulate its own depth of thinking. We treat reasoning as a spectrum, ranging from fast heuristics to deep chain-of-thought to precise tool-like solving, and we train a neural meta-controller to decide which mode to use for each task. By optimizing the trade-off between accuracy, computation cost, and a limited reasoning budget, we explore how an agent can monitor its internal state and adapt its […]

Cato Scholar: Stop Treating Jury Independence as a Defect

A 65-year-old retired doorman in Queens is heading to prison next month — not for killing his attacker in self-defense, but for possessing the unlicensed firearm that saved his life. lead , In a recent op-ed titled He Held the Door for Years, But the Court Slammed One on Him, Cato scholar Mike Fox details how American juries have strayed from the founders’ intent of being the community’s conscience, in part writing: , “We have replaced community conscience with […]
