The video computing group led by Prof. Amit Roy-Chowdhury has recently developed a new method that can detect manipulated facial expressions in deepfake videos with higher accuracy than current state-of-the-art methods. The method also works as well as current methods in cases where the facial identity, but not the expression, has been swapped, leading to...
Deep neural networks, or DNNs — layers of algorithms that perform computations in an orderly progression to make the apps work — need to be optimized for each device. On other devices, it can take longer for the DNN to perform computations, causing the app to lag. This lag is known to computer scientists as...
Machine learning applications have observed tremendous breakthroughs by the abundance of data in today's world, including the data collected by everyday devices such as smart phones, cars, and home appliances. The data collected in such environments, however, often carries sensitive personal information, such as personal identifiable information, images, videos, financial transactions, or geolocation information, the...
