Last Week in AI #160: Super fast 3D perception from Nvidia, Ukraine uses face recognition to identify dead Russian soldiers, US-China AI collaboration drops, and more!
Nvidia improves performance of NeRF by many orders of magnitudes, Ukraine uses facial recognition to identify dead Russian soldiers and notifies their families, dip in US-China co-authored AI papers
Neural Radiance Fields (NeRF) is a technique for representing 3D scenes with neural networks. The NeRF neural network is trained with camera images of a scene, and it can then be used to extract information about the scene, like geometry, materials, and lighting, as well as render views of the scene from new camera angles. Ever since its inception in 2020, NeRF has taken the world of computer vision by storm, with a myriad of papers improving its performance and exploring creative applications. This new paper from Nvidia resolves one of NeRF’s most frustrating drawbacks, which is its slow training and rendering time. Combining a smaller NeRF network with a hash table, Nvidia’s researchers reduced the NeRF training time from hours to seconds, and rendering time from minutes to tens of milliseconds.
Our take: Achieving these many order of magnitudes speed-ups is an important advance in the “application” phase of NeRF that will see its deployment in real applications outside of research labs. It’s very likely that within another year or two, we will see NeRF used in a wide range of actual products in areas like 3D content creation, video games, VR, building inspections, video conferencing, robotics, and more.
Reuters exclusively reported that Ukraine's Ministry of Defense this month began using technology from Clearview AI, a New York-based facial recognition provider that finds images on the web that match faces from uploaded photos. Now, Mykhailo Fedorov, Ukraine's vice prime minister who also runs the ministry of digital transformation, told Reuters Ukraine had been using Clearview AI software to find the social media accounts of dead Russian soldiers. From there, authorities are messaging relatives to make arrangements to collect the body, he said.
"As a courtesy to the mothers of those soldiers, we are disseminating this information over social media to at least let families know that they they've lost their sons and to then enable them to come to collect their bodies," Fedorov said in an interview, speaking via a translator.
Our take: Use of Clearview AI’s technology has been steadily increasing among US law enforcement, but this is the first reported case in which it has been used in a war. As facial recognition technology of this quality is relatively new, it is likely that this instance also represents one of the first cases of using AI to identify KIA soldiers. The fact that Ukraine can use Clearview AI’s services to identify Russian soldiers, despite the company being US-based, showcases just how far reaching their database is. While this is clearly a positive way to use the technology, it also highlights once again how far reaching the implications of such technology can be — especially when it is not constrained by laws and regulations.
Souring US-China relations have begun to manifest in their collaborations on AI papers. According to a report from Stanford's Institute for Human-Centered Artificial Intelligence, 2021 saw 9,660 papers co-authored by researchers from US and Chinese institutions. While this number is a decrease from the 10,000 papers US and Chinese researchers co-wrote the year before, US-China AI cooperation still leads the world. Additionally, while China leads the US in its number of AI publications and patent applications, the US remains ahead in citations and granted patents
Our Take: It's expected that worsening US-China relations and the resulting decouplings would show up in numbers describing their cooperation. The fact that the US and China still cooperate in AI research more than any other pair does speak to the realities of their integration. It seems unlikely that the two nations will be able to entirely decouple, economically or in research. But it will be interesting to watch how much AI research begins to diverge between the two countries and how much this tracks the status of their relationship.
