CSET produces evidence-driven analysis in a variety of forms, from informative graphics and translations to expert testimony and published reports. Our key areas of inquiry are the foundations of artificial intelligence — such as talent, data and computational power — as well as how AI can be used in cybersecurity and other national security settings. We also do research on the policy tools that can be used to shape AI’s development and use, and on biotechnology.

New Student Visa Rule Likely to Harm National Security More Than Help

Jason Matheny and Zachary Arnold
| October 26, 2020

CSET submitted the following comment to the Department of Homeland Security regarding a fixed time period of admission for nonimmigrant students, exchange visitors and representatives of foreign information media.

The United States has long used export controls to prevent the proliferation of advanced semiconductors and the inputs necessary to produce them. With Beijing building up its own chipmaking industry, the United States has begun tightening restrictions on exports of semiconductor manufacturing equipment to China. This brief provides an overview of U.S. semiconductor export control policies and analyzes the impacts of those policies on U.S.-China trade.

Downscaling Attack and Defense

Andrew Lohn
| October 7, 2020

The resizing of images, which is typically a required part of preprocessing for computer vision systems, is vulnerable to attack. Images can be created such that the image is completely different at machine-vision scales than at other scales and the default settings for some common computer vision and machine learning systems are vulnerable.
