New index preserves AI search accuracy as records are added and deleted

When new information is continually added and old information is removed, an AI system may fail to find the correct material even when that material exists. KAIST researchers have developed a vector database technology that ...

Can scientists build a lie detector for AI chatbots?

Ask an AI chatbot for some medical advice and it might recommend you head to the hospital when all you really have is indigestion. One of the biggest issues with AI chatbots today is that they can still share false information, ...

Computer Sciences

The tests that grade AI may be getting it wrong

Before a new AI model reaches the public, its developers run it through a battery of tests known as "benchmarks," which score it on everything from reasoning ability to how safe it is for people to use. Billions of investment ...

How randomness tames vast network problems

Networks are everywhere. They connect computers across the internet, carry electricity through power grids and represent transport routes for moving people and goods. Yet many problems that appear to have nothing to do with ...

A simple physics-inspired model sheds light on how AI learns

Artificial intelligence systems based on neural networks—such as ChatGPT, Claude, DeepSeek or Gemini—are extraordinarily powerful, yet their internal workings remain largely a "black box." To better understand how these systems ...

When AI can't count—and what researchers are doing about it

Today, artificial intelligence can describe images, recognize objects, and explain complex relationships. The pace of development is remarkable: So-called vision-language models (VLMs) combine text and image understanding ...
