Brain Connections: Neuromorphic Devices Emulate the Brain’s Hardware

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

Nowadays, there is an imperative need for novel computational concepts to manage the enormous data volume produced by contemporary information technologies. The inherent capability of the brain to cope with these kinds of signals constitutes the most efficient computational paradigm for biomimicry.

Representing neuronal processing with software-based artificial neural networks is a popular approach with tremendous impacts on everyday life; a field commonly known as machine learning or artificial intelligence. This approach relies on executing algorithms that represent neural networks on a traditional von Neumann computer architecture.

An alternative approach is the direct emulation of the workings of the brain with actual electronic devices/circuits. This emulation of the brain at the hardware-based level is not only necessary for overcoming limitations of conventional silicon technology based on the traditional von Neumann architecture in terms of scaling and efficiency, but in understanding brain function through reverse engineering. This hardware-based approach constitutes the main scope of neuromorphic devices/computing.

Research on Application of Artificial Intelligence in Computer Network Technology

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

This paper attempts to apply artificial intelligence (AI) to computer network technology and research on the application of AI in computing network technology.

With the continuous expansion of the application scope of computer network technology, various malicious attacks that exist in the Internet range have caused serious harm to computer users and network resources.

By studying the attack principle, analyzing the characteristics of the attack method, extracting feature data, establishing feature sets, and using the agent technology as the supporting technology, the simulation experiment is used to prove the improvement effect of the system in terms of false alarm rate, convergence speed, and false-negative rate, the rate reached 86.7%. The results show that this fast algorithm reduces the training time of the network, reduces the network size, improves the classification performance, and improves the intrusion detection rate.

How Machines Are Taking Over the World’s Stock Markets

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

Marcos López de Prado has been at the forefront of machine learning innovation in finance. The New-York based Spaniard was the first-ever head of machine learning at AQR, one of the world’s largest investment management firms, before he left earlier this year to start his own firm, which sells machine learning expertise and algorithms to Wall Street.

Science, not speculation, is the right way to invest, a top expert tells TIME.

New tool reveals DNA structures that influence disease

Posted by in categories: biotech/medical, information science

Disruption of certain DNA structures—called topologically associating domains, or TADs—is linked with the development of disease, including some cancers. With its newly created algorithm that quickly locates and helps elucidate the complex functions of TADs, an international team of researchers is making it easier to study these important structures and help prevent disease.

“On your DNA you have and regulatory elements—such as promotors and enhancers—that , but these two things can be far away from each other,” said Qunhua Li, associate professor of statistics, Penn State. “Similar to a dresser drawer that keeps your clothes organized and available for use, TADs bring genes together with their regulatory elements, which enables them to begin the process of gene expression.”

Gene expression is the process by which the information encoded in DNA gives rise to observable traits.

AI super resolution lets you “zoom and enhance” in Pixelmator Pro

Posted by in categories: information science, robotics/AI

Machine learning and AI can now restore lost detail to blurry images. Many companies and labs have created such “super resolution” algorithms, but this software is now becoming commercially available, too. Pixelmator Pro is among the first image editors to offer such a tool.

AI is outpacing Moore’s Law

Posted by in categories: information science, robotics/AI

In 1965, American engineer Gordon Moore made the prediction that the number of transistors integrated on a silicon chip doubles every two years or so. This has proven to be true to this day, allowing software developers to double the performance of their applications. However, the performance of artificial intelligence (AI) algorithms seems to have outpaced Moore’s Law.

According to a new report produced by Stanford University, AI computational power is accelerating at a much higher rate than the development of processor chips.

“Prior to 2012, AI results closely tracked Moore’s Law, with compute doubling every two years,” the authors of the report wrote. “Post-2012, compute has been doubling every 3.4 months.”

About AI bias.

Yet AI bias is by itself a biased term, as if the machine/algorithm were to blame for human bias and/or an incorrect data set.

Cheers! Maxwell’s electromagnetism extended to smaller scales

Posted by in categories: information science, nanotechnology

On Dec. 11, 2019, a general framework for incorporating and correcting for nonclassical electromagnetic phenomena in nanoscale systems will be presented in the journal Nature.

More than 150 years have passed since the publication of James Clerk Maxwell’s “A Dynamical Theory of the Electromagnetic Field” (1865). His treatise revolutionized the fundamental understanding of electric fields, magnetic fields and light. The 20 original equations (elegantly reduced to four today), their boundary conditions at interfaces, and the bulk electronic response functions (dielectric permitivity and magnetic permeability) are at the root of the ability to manipulate electromagnetic fields and light.

Life without Maxwell’s equations would lack most current science, communications and technology.
