DARPA snags Intel to lead its machine learning security tech

Posted by in categories: cybercrime/malcode, information science, military, robotics/AI

Chip maker Intel has been chosen to lead a new initiative led by the U.S. military’s research wing, DARPA, aimed at improving cyber-defenses against deception attacks on machine learning models.

Machine learning is a kind of artificial intelligence that allows systems to improve over time with new data and experiences. One of its most common use cases today is object recognition, such as taking a photo and describing what’s in it. That can help those with impaired vision to know what’s in a photo if they can’t see it, for example, but it also can be used by other computers, such as autonomous vehicles, to identify what’s on the road.

But deception attacks, although rare, can meddle with machine learning algorithms. Subtle changes to real-world objects can, in the case of a self-driving vehicle, have disastrous consequences.

AI reveals that mice’s faces express a range of emotions — just like humans

Posted by in categories: information science, robotics/AI

AI has revealed that mice have a range of facial expressions that show they feel — offering fresh clues about how emotional responses arise in human brains.

Scientists at the Max Planck Institute of Neurobiology in Germany made the discovery by recording the faces of lab mice when they were exposed to different stimuli, such as sweet flavors and electric shocks. The researchers then used machine learning algorithms to analyze how the rodents’ faces changed when they experienced different feelings.

A Robot Stand-Up Comedian Learns The Nuts And Bolts Of Comedy

Posted by in categories: information science, robotics/AI

Social roboticist, Heather Knight, sees robots and entertainment a research-rich coupling. So she programmed a charming humanoid robot named DATA with jokes, and equipped it with sensors and algorithmic capabilities to help with timing and gauging a crowd. Then Knight and DATA hit the road on an international robot stand-up comedy tour. Their act landed stage time at a TED conference and Knight was profiled in Forbes 30 Under 30. Watching Data perform is much like watching an amateur stand-up comedian cutting her/his chops at an open mic night doing light comedy with a sweet but wooden delivery.

Knight’s goal is specific:

AI techniques used to improve battery health and safety

Posted by in categories: health, information science, mobile phones, robotics/AI, transportation

Researchers have designed a machine learning method that can predict battery health with 10x higher accuracy than current industry standard, which could aid in the development of safer and more reliable batteries for electric vehicles and consumer electronics.

The researchers, from Cambridge and Newcastle Universities, have designed a new way to monitor batteries by sending electrical pulses into them and measuring the response. The measurements are then processed by a to predict the ’s health and useful lifespan. Their method is non-invasive and is a simple add-on to any existing battery system. The results are reported in the journal Nature Communications.

Predicting the state of health and the remaining useful lifespan of lithium-ion batteries is one of the big problems limiting widespread adoption of : it’s also a familiar annoyance to mobile phone users. Over time, battery performance degrades via a complex network of subtle chemical processes. Individually, each of these processes doesn’t have much of an effect on battery performance, but collectively they can severely shorten a battery’s performance and lifespan.

Alphabet’s DeepMind masters Atari games

Posted by in categories: entertainment, information science, robotics/AI

In order to better solve complex challenges at the dawn of the third decade of the 21st century, Alphabet Inc. has tapped into relics dating to the 1980s: video games.

The parent company of Google reported this week that its DeepMind Technologies Artificial Intelligence unit has successfully learned how to play 57 Atari video games. And the plays better than any human.

Three Questions that Keep Me Up at Night

Posted by in categories: information science, robotics/AI, transportation

A Google interview candidate recently asked me: “What are three big science questions that keep you up at night?” This was a great question because one’s answer reveals so much about one’s intellectual interests — here are mine:

Q1: Can we imitate “thinking” from only observing behavior?

Suppose you have a large fleet of autonomous vehicles with human operators driving them around diverse road conditions. We can observe the decisions made by the human, and attempt to use imitation learning algorithms to map robot observations to the steering decisions that the human would take.

Meet Ai-Da, the world’s first AI artist, who is almost human

Posted by in categories: information science, robotics/AI

Ai-Da is the world’s first ultra-realistic artist robot powered by AI and named after Ada Lovelace, the first female computer programmer in the world. She is a humanoid with human facial features and a robotic body created by the Oxfordians, a group of cutting-edge art and technology experts. Embedded with a groundbreaking algorithm, she has taken the scientific and art world by surprise, now becoming an intense subject of conversation in over 900 publications worldwide. She has already collaborated with Tate Exchange and WIRED at the Barbican, Ars Electronica, and will be performing at the Louvre Abu-Dhabi later this year.

Here, she discusses what it means to identify as a creative without a consciousness with Futurist Geraldine Wharry.
