The Next Web: New Zealand’s first AI police officer reports for duty. “New Zealand Police has recruited an unusual new officer to the force: an AI cop called Ella. Ella is a life-like virtual assistant that uses real-time animation to emulate face-to-face interaction in an empathetic way.”
The Next Web: Reuters built a prototype for automated news videos using Deepfakes tech. “The Reuters news company and an AI startup named Synthesia today unveiled a new project they’ve partnered on that uses Deepfakes-style technology to generate automated news reports in real time.”
Boing Boing: Neural network restores and colorizes old movies. “From the excellent “Two Minute Papers” YouTube channel, a discussion of a paper titled ‘DeepRemaster: Temporal Source-Reference Attention Networks for Comprehensive Video Enhancement,’ that demonstrates the results of a neural network that fixes and colorizes aged, blurry, scratchy films.” My husband and I watched this last night. I’m kind of a snob about AI-based colorizing, so that was eh, but the restoration of old/degraded video was absolutely remarkable.
The Register: Facebook mulls tagging pics with ‘radioactive’ markers to trace the origin of photos used to build image-recog AI. “Facebook researchers have developed a digital watermarking technique that allows developers to tell if a particular machine-learning model was trained using marked images.”
TechCrunch: Facebook speeds up AI training by culling the weak. “Training an artificial intelligence agent to do something like navigate a complex 3D world is computationally expensive and time-consuming. In order to better create these potentially useful systems, Facebook engineers derived huge efficiency benefits from, essentially, leaving the slowest of the pack behind.”
Ars Technica: How Google researchers used neural networks to make weather forecasts. “The researchers say their results are a dramatic improvement over previous techniques in two key ways. One is speed. Google says that leading weather forecasting models today take one to three hours to run, making them useless if you want a weather forecast an hour in the future. By contrast, Google says its system can produce results in less than 10 minutes—including the time to collect data from sensors around the United States.”
News@Northeastern: He’s Training Computers To Find New Molecules With The Machine Learning Algorithms Used By Facebook And Google. “For more than a decade, Facebook and Google algorithms have been learning as much as they can about you. It’s how they refine their systems to deliver the news you read, those puppy videos you love, and the political ads you engage with. These same kinds of algorithms can be used to find billions of molecules and catalyze important chemical reactions that are currently induced with expensive and toxic metals, says Steven A. Lopez, an assistant professor of chemistry and chemical biology at Northeastern.”
