Smartphones, security cameras, and speakers are just a few of the devices that will soon be running more artificial intelligence software to speed up image- and speech-processing tasks. A compression technique known as quantization is smoothing the way by making deep learning models smaller to reduce computation and energy costs. But smaller models, it turns out, make it easier for malicious attackers to trick an AI system into misbehaving — a concern as more complex decision-making is handed off to machines.  In a new study, MIT and IBM researchers show just how vulnerable compressed AI models are to adversarial attack, and they offer a fix: add a mathematical constraint during the quantization process to reduce the odds that an AI will fall prey to a slightly modified image and misclassify what they see.  When a deep learning model is reduced from the standard 32 bits to a lower bit length, it’s more likely Continuer la lecture Improving security as artificial intelligence moves to smartphones→

Community forums held last week for the MIT Stephen A. Schwarzman College of Computing working groups addressed how new ideas for its curriculum, research, infrastructure, and operations can best serve the community and society. In February, MIT charged five working groups with generating ideas for the structure and operation of the new college. The groups are: Academic Degrees, Social Implications and Responsibilities of Computing, Organizational Structure, Faculty Appointments, and Computing Infrastructure. The groups each have two co-chairs and anywhere from about a dozen to more than 20 other members, representing many departments, labs, and centers across the Institute. The groups meet regularly, and will soon submit a report to MIT administration that outlines many potential ideas for their respective assignments. To keep the community updated, three forums for all five working groups were held Wednesday, April 17, and Thursday, April 18. Co-chairs and members for each group delivered brief presentations Continuer la lecture Forums address MIT’s plans to reshape its computer science education→
