Watson Lecture on May 24: Yaser Abu-Mostafa Will Discuss the Promise and Perils of AI
On Wednesday, May 24, at 7:30 p.m. PDT in Beckman Auditorium on the Caltech campus, Yaser Abu-Mostafa (PhD '83), professor of electrical engineering and computer science, will cap the 100th anniversary season of the Earnest C. Watson Lecture Series with "Artificial Intelligence: The Good, the Bad, and the Ugly."
ChatGPT has rocked the general public’s perception and expectations of artificial intelligence (AI). In this lecture, Abu-Mostafa will explain the science of AI in plain language and explore how these details illustrate the risks and benefits of AI. Between the extremes of "AI will kill us all" and "AI will solve all our problems," the science can help us identify what is realistic and what is speculative, and guide us in our planning, legislation, and investment in AI.

Ask a Caltech Expert: Machine Learning for Conservation
As part of Conversations on Artificial Intelligence, a webinar series hosted by the Caltech Science Exchange, two artificial intelligence (AI) researchers—Pietro Perona and Suzanne Stathatos—discussed AI’s potential as a powerful tool for wildlife conservation and biodiversity research.
Perona is the Allen E. Puckett Professor of Electrical Engineering at Caltech, and Stathatos is a graduate student who was a software engineer at Amazon and JPL, which Caltech manages for NASA, before coming to Caltech.
In conversation with Caltech science writer Robert Perkins, the engineers describe AI applications for identifying and tracking wildlife that offer fresh insights to biologists and other individuals interested in the environment. [Caltech story]

Wavefront Shaping: From Telescopes to Biological Tissue
Researchers, led by Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering, have made a major step forward in medical imaging by taking inspiration from the field of astronomy. In astronomy, the light that reaches telescopes is distorted by the earth's atmosphere, resulting in blurry images of planets, satellites, and other cosmic objects. The earth's atmosphere is what's known as a scattering medium; it scatters light, making images appear unfocused and cloudy. Wavefront shaping is a method of generating focused light by reversing the optical distortion caused by the atmosphere. In this method, a reflective device, like a mirror, "shapes" light waves to counterbalance distortion. It's similar to a person wearing active noise-cancelling headphones to combat ambient noise.
