If you are looking for an answer to the question What is Artificial Intelligence? and you only have a minute, then here's the definition the Association for the Advancement of Artificial Intelligence offers on its home page: "the scientific understanding of the mechanisms underlying thought and intelligent behavior and their embodiment in machines."
However, if you are fortunate enough to have more than a minute, then please get ready to embark upon an exciting journey exploring AI (but beware, it could last a lifetime) …
Imagine standing up to give a speech in front of a critical audience. As you do your best to wax eloquent, someone in the room uses a clicker to conspicuously count your every stumble, hesitation, um and uh; once you've finished, this person loudly announces how many of these blemishes have marred your presentation. This is exactly the tactic used by the Toastmasters public-speaking club, in which a designated "Ah Counter" is charged with tallying up the speaker's slip-ups as part of the training regimen. The goal is total eradication. The club's punitive measures may be extreme, but they reflect the folk wisdom that ums and uhs betray a speaker as weak, nervous, ignorant, and sloppy, and should be avoided at all costs, even in spontaneous conversation.
Loihi is Intel's novel, manycore neuromorphic processor and is the first of its kind to feature a microcode-programmable learning engine that enables on-chip training of spiking neural networks (SNNs). The authors present the Loihi toolchain, which consists of an intuitive Python-based API for specifying SNNs, a compiler and runtime for building and executing SNNs on Loihi, and several target platforms (Loihi silicon, FPGA, and functional simulator). To showcase the toolchain, the authors describe how to build, train, and use a SNN to classify handwritten digits from the MNIST database.
This article presents a novel approach to monitoring athletes' behavioral changes to predict a decline in motivation. When the system detects such a decline, it refers the athlete to her coach, along with a concise explanation of the detected behavioral changes. The coach thus has all the information needed for a prompt, targeted intervention.
The adoption and effectiveness of cognitive assistive technologies hinge on harnessing the dynamics of human emotion. The authors discuss seminal advances in the integration of emotions in assistive technologies for dementia and propose Bayesian Affect Control Theory (BayesACT), a quantitative social-psychological theory, to model behavior and emotion in such systems.
A self-driving car is like a regular car, but with sensors on the outside and a few powerful laptops hidden inside. The sensors, which are GPS, LIDAR, and cameras, transmit information back to the car's computer system. The best way to imagine the perspective of a self-driving car is to imagine you are driving in a 1980s-style first-person driving video game. The world is a 3-D grid with x, y, and z coordinates. The car moves through the grid from point A to point B, using highly precise GPS measurements gathered from nearby satellites.
On Sunday night, a self-driving car operated by Uber struck and killed a pedestrian, 49-year-old Elaine Herzberg, on North Mill Avenue in Tempe, Arizona. It appears to be the first time an automobile driven by a computer has killed a human being by force of impact. The car was traveling at 38 miles per hour. An initial investigation by Tempe police indicated that the pedestrian might have been at fault. According to that report, Herzberg appears to have come "from the shadows," stepping off the median into the roadway, and ending up in the path of the car while jaywalking across the street.
Family Physics" may be the best episode of Public Radio's long running show, This American Life. Import key concepts from the realms of quantum mechanics and cosmology and use them to illuminate the everyday world of parents, kids, and their interactions. Introducing the show, however, host Ira Glass was quick to point out how much physicists detest this kind of enterprise. "They hate it when non-scientists … apply principles from physics to their petty little lives and petty little relationships." Glass was equally quick to point out that he and his colleagues at the show just did not care.
