Quantum Chemistry Breakthrough: DeepMind Uses Neural Networks to Tackle Schrödinger Equation

Posted by in categories: chemistry, information science, particle physics, quantum physics, robotics/AI

Wave function represents the quantum state of an atom, including the position and movement states of the nucleus and electrons. For decades researchers have struggled to determine the exact wave function when analyzing a normal chemical molecule system, which has its nuclear position fixed and electrons spinning. Fixing wave function has proven problematic even with help from the Schrödinger equation.

Previous research in this field used a Slater-Jastrow Ansatz application of quantum Monte Carlo (QMC) methods, which takes a linear combination of Slater determinants and adds the Jastrow multiplicative term to capture the close-range correlations.

Now, a group of DeepMind researchers have brought QMC to a higher level with the Fermionic Neural Network — or Fermi Net — a neural network with more flexibility and higher accuracy. Fermi Net takes the electron information of the molecules or chemical systems as inputs and outputs their estimated wave functions, which can then be used to determine the energy states of the input chemical systems.

Investigating robot illusions and simulations of reality

Posted by in categories: information science, robotics/AI

To evaluate the performance of robotics algorithms and controllers, researchers typically use software simulations or real physical robots. While these may appear as two distinct evaluation strategies, there is a whole other range of possibilities that combine elements of both.

In a recent study, researchers at Texas A&M University and the University of South Carolina have set out to examine evaluation and execution scenarios that lie at an intersection between simulations and real implementations. Their investigation, outlined in a paper pre-published on arXiv, specifically focuses on instances in which real robots perceive the world via their sensors, where the environment they sense could be seen as a mere illusion.

“We consider problems in which robots conspire to present a view of the world that differs from reality,” Dylan Shell and Jason O’Kane, the researchers who carried out the study, wrote in their paper. “The inquiry is motivated by the problem of validating robot behavior physically despite there being a discrepancy between the robots we have at hand and those we wish to study, or the environment for testing that is available versus that which is desired, or other potential mismatches in this vein.”

EmoSense: an AI-powered and wireless emotion sensing system

Posted by in categories: biotech/medical, robotics/AI

Researchers at Hefei University of Technology in China and various universities in Japan have recently developed a unique emotion sensing system that can recognize people’s emotions based on their body gestures. They presented this new AI- powered system, called EmoSense, in a paper pre-published on arXiv.

“In our , we can clearly realize that body gestures contain rich mood expressions for ,” Yantong Wang, one of the researchers who carried out the study, told TechXplore. “Meanwhile, we can also find out that human body gestures affect via shadowing and multi-path effects when we use antennas to detect behavior. Such signal effects usually form unique patterns or fingerprints in the temporal-frequency domain for different gestures.”

Wang and his colleagues observed that human body gestures can affect wireless signals, producing characteristic patterns that could be used for emotion recognition. This inspired them to develop a system that can identify these patterns, recognizing people’s emotions based on their physical movements.

Driverless cars will lead to more sex in cars, study finds

Posted by in categories: robotics/AI, sex, transportation

Self-driving vehicles will lead to a rise in car sex, according to a new study.

People will be more likely to eat, sleep and engage in on-the-road hanky-panky when robot cars become the new normal, according to research published in the most recent issue of the journal Annals of Tourism Research.

“People will be sleeping in their vehicles, which has implications for roadside hotels. And people may be eating in vehicles that function as restaurant pods,” Scott Cohen, who led the study, told Fast Company magazine.

Ministry of Defence is developing ‘military Alexa’ to give soldiers crucial information using artificial intelligence

Posted by in categories: military, robotics/AI

Hey Google, how many enemy combatants remain standing?

British soldiers could soon be offered a “military Alexa” digital assistant which would provide troops in the field with automated information from combat tactics to repair instructions.

The Ministry of Defence has awarded a £700,000 contract to a British technology company to explore the feasibility of an artificial intelligence “chatbot” which will allow soldiers on deployment to obtain crucial information via computer link.
