The free-energy principle explains the brain

January 17, 2022 by Editor Leave a Comment

The Riken Center for Brain Science (CBS) in Japan, along with colleagues, has shown that the free-energy principle can explain how neural networks are optimized for efficiency.

Published in the scientific journal Communications Biology, the study first shows how the free-energy principle is the basis for any neural network that minimizes energy cost. Then, as proof-of-concept, it shows how an energy minimizing neural network can solve mazes.

This finding will be useful for analyzing impaired brain function in thought disorders as well as for generating optimized neural networks for artificial intelligences. [Read more…] about The free-energy principle explains the brain

VR visualization supports research on molecular networks

April 29, 2021 by Editor

Networks offer a powerful way to visualize and analyze complex systems. However, depending on the size and complexity of the network, many visualizations are limited. Protein interactions in the human body constitute such a complex system that can hardly be visualized.

Jörg Menche, Adjunct Principal Investigator at the CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences, Professor at the University of Vienna and research group leader at Max Perutz Labs (Uni Wien/MedUni), and his team developed an immersive virtual reality (VR) platform that solves this problem.

With the help of VR visualization of protein interactions, it will be possible in the future to better recognize correlations and identify those genetic aberrations that are responsible for rare diseases. [Read more…] about VR visualization supports research on molecular networks

Following nature’s cue, researchers build successful, sustainable industrial networks

April 28, 2021 by Editor

By translating the pattern of interconnections between nature’s food chains to industrial networks, researchers at Texas A&M University have delineated guidelines for setting up successful industrial communities.

The researchers said this guidance can facilitate economic growth, lower emissions and reduce waste while simultaneously ensure that partnering industries can recover from unexpected disturbances.

“Industries can often partner up to exchange byproducts and over time these industries might form bigger communities. While these networks sound quite beneficial to all industry partners within the community, they are not always successful,” said Dr. Astrid Layton, assistant professor in the J. Mike Walker’ 66 Department of Mechanical Engineering. [Read more…] about Following nature’s cue, researchers build successful, sustainable industrial networks

Towards 6G wireless communication networks: vision, enabling technologies, and new paradigm shifts

November 30, 2020 by Editor

The fifth generation (5G) wireless communication networks are being deployed worldwide from 2020 and more capabilities are in the process of being standardized, such as mass connectivity, ultra-reliability, and guaranteed low latency.

However, 5G will not meet all requirements of the future in 2030 and beyond, and sixth generation (6G) wireless communication networks are expected to provide global coverage, enhanced spectral/energy/cost efficiency, better intelligence level and security, and so on.

To meet these requirements, 6G networks will rely on new enabling technologies; that is, air interface and transmission technologies and novel network architecture, such as waveform design, multiple access, channel coding schemes, multi-antenna technologies, network slicing, cell-free architecture, and cloud/fog/edge computing.

A neural network learns when it should not be trusted

November 27, 2020 by Editor

Increasingly, artificial intelligence systems known as deep learning neural networks are used to inform decisions vital to human health and safety, such as in autonomous driving or medical diagnosis.

These networks are good at recognizing patterns in large, complex datasets to aid in decision-making. But how do we know they’re correct? Alexander Amini and his colleagues at MIT and Harvard University wanted to find out.

They’ve developed a quick way for a neural network to crunch data, and output not just a prediction but also the model’s confidence level based on the quality of the available data. The advance might save lives, as deep learning is already being deployed in the real world today. [Read more…] about A neural network learns when it should not be trusted

The road to Terabit Ethernet

October 17, 2017 by Editor Leave a Comment

 

The race towards Terabit Ethernet, or TbE, has apparently taken a great leap with the completion of what is claimed to be the world’s first test of a 400-gigabit ethernet network. 

The 400 GbE trial was conducted by Huawei with its partner, China Telecom, the state telecommunications infrastructure provider.

The companies say the results indicate their superfast 400 GbE network technology is ready for commercial utilisation.  [Read more…] about The road to Terabit Ethernet
