Optimal strategies for the control of autonomous vehicles in data assimilation

arXiv.org Machine Learning

We propose a method to compute optimal control paths for autonomous vehicles deployed for the purpose of inferring a velocity field. In addition to being advected by the flow, the vehicles are able to effect a fixed relative speed with arbitrary control over direction. It is this direction that is used as the basis for the locally optimal control algorithm presented here, with objective formed from the variance trace of the expected posterior distribution. We present results for linear flows near hyperbolic fixed points.

Did you ever stop to wonder: What is Amazon not doing with technology? These days, you'd be hard-pressed to answer that question, given the company's incessant schedule for announcing updates and new products. The Seattle-based e-commerce giant is seemingly everywhere--whether it's the latest cloud offerings in AWS, new entertainment shows on Prime, automated retail stores, leased fleets of Boeing jets, smart speakers, payment systems, autonomous cars and trucks, freight forwarding companies, or airborne warehouses. Amazon also happens to have warehouses within 20 miles of 44% of the population of the United States, according to Piper Jaffray analyst Gene Munster. In many of the company's recent announcements, Amazon's voice assistant Alexa plays a central role.


CES for Marketers: Alexa Wows, Virtual Reality Underwhelms

#artificialintelligence

Over the past few years the CES trade show has become a familiar post-holidays pilgrimage for many of the country's biggest marketers. They see the event as a way to get a sneak peek at the latest tech gadgets and technologies that can help them engage with their customers. This year marketing executives from companies such as Coca-Cola, Unilever, Johnson & Johnson, Campbell Soup and PepsiCo Inc. made their way to Las Vegas for the gathering. The convention was jam-packed with everything from self-driving cars to robots that play chess to Procter & Gamble's air-freshener spray that can connect with Alphabet Inc.'s Nest home to automatically release pleasant scents in the home. But there was one category that seemed to especially win over marketers: virtual assistants.


Apple and its slowly evolving AI ambitions: column

USA TODAY's Jefferson Graham and Jon Swartz offer their take on Apple's WWDC developer conference, and how it stacked up to recent Facebook and Google sessions for developers. SAN FRANCISCO -- We've been here before, crammed in a luxurious theater, music pulsating, fellow reporters tweeting, anxiously awaiting Apple's vision to match the razzle-dazzle from recent Facebook and Google events. At WWDC, Apple's annual conference for software developers, there was a fleeting flash today of what it has in story for the "it" technology of the moment: artificial intelligence. For several minutes during a two-hour presentation, Apple offered a glimpse into its immediate plans for Siri, the voice-activated agent that stands to get more relevant with better AI. Siri will be able to scan Apple TV for genre-specific movies, Apple execs said.
