What if AI agents could improve themselves without increasing deployment cost?

CS faculty Xin Eric Wang and researcher Zhaotian Weng were recently featured in for their work on Group-Evolving Agents (GEA)—a new framework that helps AI systems adapt and improve collectively, without requiring constant human intervention.

In rigorous benchmarks, GEA substantially outperformed prior self-evolving approaches and matched leading human-designed frameworks, all while maintaining standard inference costs at deployment.

We are proud to see this work recognized and progress toward a more resilient, self-improving AI systems.

🧠 Research Highlight 🎉

How do we focus on something without even moving our eyes? 🤔

New research from UCSB Computer Science and Psychological & Brain Sciences, led by faculty members William Wang and Miguel Eckstein, uses artificial intelligence to uncover the neural foundations of covert attention—and reveals previously unknown neuron types along the way.

The study shows that attention can emerge naturally through learning—without any built-in attention mechanism—after analyzing convolutional neural networks.

Congratulations to Professors Wang and Eckstein on these exciting findings and on work that is reshaping how we understand attention and the brain!
