More-flexible machine learning

ScienceDaily's AI News - Thu, 01/10/2015 - 14:21
Researchers have presented a new way of doing machine learning that enables semantically related concepts to reinforce each other. So, for instance, an object-recognition algorithm would learn to weigh the co-occurrence of the classifications 'dog' and 'Chihuahua' more heavily than it would the co-occurrence of 'dog' and 'cat.'

Cheaters sometimes prosper on Facebook

ScienceDaily's AI News - Tue, 29/09/2015 - 14:20
What does it mean to cheat in a Facebook game like FarmVille? Is it any different from breaking the rules in a traditional videogame like World of Warcraft? New research shows that players often dismiss the seriousness of social network games -- meaning cheating isn't so serious when it's done on Facebook.

Mobile robots could help the elderly live fuller lives, experts say

ScienceDaily's AI News - Tue, 29/09/2015 - 11:21
Mobile service robots developed by computer scientists could soon be helping elderly people stay independent and active for longer. The project, which includes artificial intelligence and robotics experts, will include a large-scale evaluation where robots will be deployed within the extra-care homes of LACE Housing Association in the UK, to care homes in Greece and to elderly people's own homes in Poland, for one year.

Crunching numbers: Math equations help build optimal bird wing

ScienceDaily's AI News - Mon, 28/09/2015 - 15:59
A researcher uses numbers to show how to build the best wing or fin. Specifically, he wanted to know how flexible the wings or fins should be, so that if an engineer designed a flying or swimming drone, they could create the most effective one possible.

A light touch: Embedded optical sensors could make robotic hands more dexterous

ScienceDaily's AI News - Mon, 28/09/2015 - 12:43
Optical sensors may be uniquely suited for use in robotic hands, according to researchers who have developed a three-fingered soft robotic hand with multiple embedded fiber optic sensors. They also have created a new type of stretchable optical sensor.

Babies time their smiles to make their moms smile in return

ScienceDaily's AI News - Wed, 23/09/2015 - 15:14
Why do babies smile when they interact with their parents? Could their smiles have a purpose? A team of computer scientists, roboticists and developmental psychologists confirm what most parents already suspect: when babies smile, they do so with a purpose -- to make the person they interact with smile in return. To verify their findings, researchers programmed a toddler-like robot to behave like the babies they studied and had the robot interact with undergraduate students.

New smart robot accelerates cancer treatment research

ScienceDaily's AI News - Tue, 22/09/2015 - 10:44
A new smart research robot accelerates research on cancer treatments by finding optimal treatment combinations, experts report. For patients with the same cancer type returning multiple times, sometimes the cancer cells develop resistance against the pharmacotherapy used. The new robot systems may also become important in the efforts to find new drug compounds that make these resistant cells sensitive again, they add.

Darwin on a chip: New electronic circuits mimic natural networks like the human brain

ScienceDaily's AI News - Mon, 21/09/2015 - 13:39
Researchers have demonstrated working electronic circuits that have been produced in a radically new way, using methods that resemble Darwinian evolution. The size of these circuits is comparable to the size of their conventional counterparts, but they are much closer to natural networks like the human brain. The findings promise a new generation of powerful, energy-efficient electronics.

Mind your manners, robot: How social cues influence human-robot interaction

ScienceDaily's AI News - Mon, 21/09/2015 - 13:39
New research examines the importance of social cues when evaluating the role of trust in human-robot interaction.

Artificial intelligence system solves sat geometry questions as well as average human test taker

ScienceDaily's AI News - Mon, 21/09/2015 - 09:51
Computer science researchers have created an artificial intelligence (AI) system that can solve SAT geometry questions as well as the average American 11th-grade student, a breakthrough in AI research.

Researchers to develop robotic device to help visually impaired

ScienceDaily's AI News - Fri, 11/09/2015 - 14:11
A project to build a wearable robotic device could help millions of visually impaired people.

Tinder-tinkering artificial intelligence could lessen left-swiping

ScienceDaily's AI News - Wed, 09/09/2015 - 13:06
An artificial intelligence programme to improve Tinder suggestions has been developed by a post-doctoral researcher who was sick of swiping left. Signing up for an account was one of the first things he did upon arriving in the city in August 2014, but he was disappointed with the results. Noting that the app failed to take note of his user history in order to better target the women he might like, he developed new software to improve his experience.

A humanoid robot to liaise between space station crews

ScienceDaily's AI News - Mon, 07/09/2015 - 10:21
A team of researchers has developed "an autobiographical memory" for the robot Nao, which enables it to pass on knowledge learnt from humans to other, less knowledgable humans. This technological progress could notably be used for operations on the International Space Station, where the robot, which is the only permanent member, would liaise between the different crews that change every six months in order to pass on information.

Artificial intelligence authors crowdsourced interactive fiction

ScienceDaily's AI News - Wed, 02/09/2015 - 13:51
Researchers have developed a new artificially intelligent system that crowdsources plots for interactive stories, which are popular in video games and let players choose different branching story options.

Self-driving golf carts

ScienceDaily's AI News - Tue, 01/09/2015 - 20:48
An experiment conducted over six days at a large public garden in Singapore demonstrated self-driving golf carts that ferried 500 tourists around winding paths trafficked by pedestrians, bicyclists, and the occasional monitor lizard.

Robotically steered flexible needles navigate in tissue

ScienceDaily's AI News - Wed, 26/08/2015 - 08:21
Robotically steering flexible needles can reach their intended target in tissue with sub-millimetre level accuracy. A major advantage of steering flexible needles is that one can avoid obstacles or sensitive tissues and can re-orient the path of the needle in real time as you insert the needle.

Biophysicists take small step in quest for 'robot scientist'

ScienceDaily's AI News - Tue, 25/08/2015 - 11:11
Biophysicists have taken another small step forward in the quest for an automated method to infer models describing a system's dynamics -- a so-called robot scientist.

Smooth robot movements reduce energy consumption by up to 40 percent

ScienceDaily's AI News - Mon, 24/08/2015 - 06:49
By minimizing the acceleration of industrial robots, energy consumption can be reduced by up to 40 percent -- while retaining the given production time. This is the result of a new optimization algorithm.

Instantaneous motion for new soft robots

ScienceDaily's AI News - Mon, 17/08/2015 - 16:06
Soft machines and robots are capable of moving, jumping and gripping objects thanks to soft, inflatable segments called fluidic actuators. These actuators require large amounts of air or water to change shape, making the machines slow, bulky and difficult to untether but researchers have engineered a new, soft actuator that harnesses the power of instability to trigger instantaneous movement.

Computer scientists find mass extinctions can accelerate evolution

ScienceDaily's AI News - Wed, 12/08/2015 - 15:12
Computer scientists have found that robots evolve more quickly and efficiently after a virtual mass extinction modeled after real-life disasters such as the one that killed off the dinosaurs. Beyond implications for artificial intelligence, the research supports the idea that mass extinctions actually speed up evolution by unleashing new creativity in adaptations.
