AI computer vision breakthrough IDs poachers in less than half a second

ScienceDaily's AI News - jeu, 08/02/2018 - 18:03
Researchers have long been applying AI to protect wildlife. Initially, computer scientists were using AI and game theory to anticipate the poachers' haunts, and now they have applied artificial intelligence and deep learning to spot poachers in near real-time.

3-D vision discovered in praying mantis

ScienceDaily's AI News - jeu, 08/02/2018 - 12:09
Miniature glasses have revealed a new form of 3-D vision in praying mantises that could lead to simpler visual processing for robots.

Researchers help robots 'think' and plan in the abstract

ScienceDaily's AI News - jeu, 08/02/2018 - 12:08
New research shows how robots can autonomously construct abstract representations of their surroundings and use them to plan for multi-step tasks.

Robotic fish can 'see' and mimic live fish

ScienceDaily's AI News - mer, 07/02/2018 - 14:04
Researchers tapped advances in real-time tracking software and robotics to design and test the first closed-loop control system featuring a bioinspired robotic replica interacting in three dimensions with live zebrafish. The system allows the robotic replica to both 'see' and mimic the behavior of live zebrafish in real time. Robots previously have been deployed alongside live animals to better understand animal behavior but the encounters were unidirectional.

Crowd workers, AI make conversational agents smarter

ScienceDaily's AI News - mer, 07/02/2018 - 10:17
Conversational agents such as Siri, Alexa and Cortana are great at giving you the weather, but are flummoxed when asked for unusual information, or follow-up questions. By adding humans to the loop researchers have created a conversational agent that is tough to stump. It's not the first chatbot to use human brainpower to answer a broad range of questions. What sets it apart is humans are simultaneously training its artificial intelligence, making it gradually less dependent on people.

Worm 'uploaded' to computer and taught amazing tricks

ScienceDaily's AI News - mar, 06/02/2018 - 10:58
The tiny worm C. elegans is the only living being whose neural network has been analyzed completely. It can therefore be transferred to a computer, creating a virtual copy of the worm which behaves in exactly the same way to external stimuli. Such a 'virtual worm' can learn amazing tricks -- its neural network can even be used to balance a pole, which is a standard control problem in computer science.

Lightweight robots harvest cucumbers

ScienceDaily's AI News - ven, 02/02/2018 - 12:39
Automation-intensive sectors such as the automotive industry are not the only ones to rely on robots. In more and more agricultural settings, automation systems are superseding strenuous manual labor. Scientists are now developing and testing a dual-arm robot for the automated harvesting of cucumbers.

New algorithms to train robots

ScienceDaily's AI News - ven, 02/02/2018 - 12:37
Researchers have developed new techniques for robots or computer programs to learn how to perform tasks by interacting with a human instructor.

Quantum algorithm could help AI think faster

ScienceDaily's AI News - ven, 02/02/2018 - 11:26
One of the ways that computers 'think' is by analyzing relationships within large sets of data. An international team has shown that quantum computers can do one such analysis faster than classical computers, for a wider array of data types than was previously expected.

Letting molecular robots swarm like birds

ScienceDaily's AI News - mer, 31/01/2018 - 09:56
A team of researchers has developed DNA-assisted molecular robots that autonomously swarm in response to chemical and physical signals, paving the way for developing future nano-machines.

Applying machine learning to the universe's mysteries

ScienceDaily's AI News - mar, 30/01/2018 - 12:36
Physicists have demonstrated that computers are ready to tackle the universe's greatest mysteries -- they used neural networks to perform a deep dive into data simulating the subatomic particle soup that may have existed just microseconds after the big bang.

Superconducting synapse may be missing piece for 'artificial brains'

ScienceDaily's AI News - ven, 26/01/2018 - 16:38
Researchers have built a superconducting switch that 'learns' like a biological system and could connect processors and store memories in future computers operating like the human brain.

Drones learn to navigate autonomously by imitating cars and bicycles

ScienceDaily's AI News - mar, 23/01/2018 - 10:18
A new algorithm allows drones to fly completely by themselves through the streets of a city and in indoor environments. The algorithm had to learn traffic rules and adapt training examples from cyclists and car drivers.

Engineers design artificial synapse for 'brain-on-a-chip' hardware

ScienceDaily's AI News - lun, 22/01/2018 - 15:08
Engineers have designed an artificial synapse in such a way that they can precisely control the strength of an electric current flowing across it, similar to the way ions flow between neurons. The team has built a small chip with artificial synapses, made from silicon germanium. In simulations, the researchers found that the chip and its synapses could be used to recognize samples of handwriting, with 95 percent accuracy.

Speech analysis software predicted psychosis in at-risk patients with up to 83 percent accuracy

ScienceDaily's AI News - lun, 22/01/2018 - 10:40
Computer-based analyses of speech transcripts obtained from interviews with at-risk youths were able to predict which youths would later develop psychosis within two years, with an accuracy of up to 83 percent. In two independent cohorts of young people at risk for psychosis, a disturbance in the flow of meaning when speaking, otherwise known as being tangential or going off track, predicted who would later develop psychosis.
