The Deep Learning Revolution

5/21/2020

Artificial intelligence (AI) is a branch of engineering that has traditionally ignored brains, but recent advances in biologically-inspired deep learning have dramatically changed AI and made it possible to solve difficult problems in vision, planning and natural language. If you talk to Alexa or use Google Translate, you have experienced deep learning in action. This new technology opens a Pandora's box of problems that we must confront regarding privacy, bias and jobs. Terry...

WiFire: Technology to Predict and Prevent the Spread of Wildfires

11/12/2019

Researchers at UC San Diego are working on cutting edge technology to combat the constant threat of wildfires in California. The WIFIRE Lab is a collaboration between the Qualcomm Institute and the San Diego Supercomputer Center. The technology uses big data from cameras, weather stations, topography and other sources to quickly predict where wildfires will spread. And, it's not just theoretical. Fire departments like LAFD are actively using WIFIRE to get ahead of blazes before...

Energy Efficient Software Development for the Internet of Things (IoT)

10/16/2019

Increasingly, Internet-of-Things (IoT) applications require energy efficiency, low-latency, privacy and security of code and data, and programming support that simplifies IoT software development and deployment.

Her research lab (the UCSB RACELab) develops novel approaches to code...

Ethical Issues in Cybersecurity Research - Exploring Ethics

4/1/2019

Computer security is a field that is fundamentally co-dependent — an interplay between the potential risk created by technology and the actual threats created by adversaries. The dance between defenders, technologists and attackers is one that is rich and dynamic and fuels both a large active research community and a multi-billion dollar computer security industry. Inevitably, ethical issues are exposed at multiple levels of this stack -- frequently at precisely those...

How Do Websites Personalize Recommendations for Me? - Exploring Ethics

1/31/2019

In this talk Julian McAuley, UC San Diego Computer Science and Engineering, discusses the modeling techniques behind personalized recommendation technology on the web. Examples of Recommender Systems range from simple statistical approaches like Amazon's people who bought X also bought Y links, to complex AI-based approaches that drive feed ranking on sites like Facebook. We'll discuss the models that drive these systems, look at the research questions that drive the future of...

Artificial Intelligence: What's Next?

9/13/2018

With the vast amount of data available in digital form, the field of Artificial Intelligence (AI) is evolving rapidly. In this talk, William Wang (UCSB Computer Science) summarizes the stunning achievements of Artificial Intelligence for the past decade, especially in the subareas of Machine Learning, Natural Language Processing, and Computer Vision. He also looks at big resarch challenges ahead. Recorded on 06/27/2018.

Advances in Energy Efficiency Through Cloud and Machine Learning

3/19/2018

Today, the IT Industry accounts for about 2 percent of total greenhouse gas emissions, comparable to the footprint of air travel. Will IT emission eclipse air travel one day soon? Urs Hölzle thinks the clear answer is "no": he says IT energy will decrease, and perhaps decrease significantly, over the next decade. Find out why. Hölzle is Senior Vice President of Technical Infrastructure & Google Fellow and oversees the design and operation of the servers,...

The Future Computer Science: The Rock We Tricked Into Thinking

11/13/2017

The growth of computer processors has shaped modern life and yet we still have so many important and fundamental questions remaining. UCSB Professor Tim Sherwood discusses the state of the art in computing and how the demands for energy efficient and intelligent systems is driving the creation of entirely new approaches to the problem. Recorded on 07/05/2017.

Science Fiction Became Reality

10/23/2017

The growth of computer processors has shaped modern life and yet we still have so many important and fundamental questions remaining. UCSB Professor Tim Sherwood discusses the unexpected state of the art in computing.

Internet of Things: History and Hype, Technology and Policy

8/21/2017

Although Internet-of-Things (IoT) have their roots in ideas that are decades old, it is a hot topic these days causing both excitement and concern. Proponents see traffic flowing more smoothly, electric grids operating efficiently, environmental sensing, and monitoring health. On the other hand, there are a range of security and privacy concerns that need to be addressed. Margaret Martonosi, Computer Science at Princeton, discusses key technology and policy challenges for future...

Self-Driving Cars - Exploring Ethics

6/1/2017

Self-driving and autonomous automobiles present new challenges that are not only technical, but also of a broader social, legal, and even ethical nature. Such issues will become more urgent and important as collisions and accidents involving self-driving or semi-autonomous vehicles occur more often –harming, injuring or even killing humans in the real world. Mohan Trivedi, Distinguished Professor of Electrical and Computer Engineering, founding director of the Computer...
