Computer vision algorithms have become increasingly advanced over the past decades, enabling the development of sophisticated technologies to monitor specific environments, detect objects of interest in video footage and uncover suspicious activities in CCTV recordings. Some of these algorithms are specifically designed to detect and isolate moving objects or people of interest in a video, a task known as moving target segmentation.

While some conventional algorithms for moving target segmentation attained promising results, most of them perform poorly in real-time (i.e., when analyzing videos that are not pre-recorded but are being captured in the present moment). Some research teams have thus been trying to tackle this problem using alternative types of algorithms, such as so-called quantum algorithms.

Researchers at Nanjing University of Information Science and Technology and Southeast University in China recently developed a new quantum algorithm for the segmentation of moving targets in grayscale videos. This algorithm, published in Advanced Quantum Technologies, was found to outperform classical approaches in tasks that involve the analysis of video footage in real-time.

It is. based on reinforcement learning algorithms (RL) to allow for quick robot movement.

Robotic dogs have a massive hurdle in autonomous navigation in crowded spaces. Robot navigation in crowds has applications in various fields, including shopping mall service robots, transportation, healthcare, etc.

To facilitate rapid and efficient movement, developing new methods is crucial to enable robots to navigate crowded spaces and obstacles safely.

Scroll Prize.

But they were so delicate and prone to turn ash if mishandled that they couldn’t be read. Previous scientists studying the scrolls could make out some Greek letters and symbols and even trained a machine-learning algorithm to read the blank ink of Herculaneum.

“The CIA and other US intelligence agencies will soon have an AI chatbot similar to ChatGPT. The program, revealed on Tuesday by Bloomberg, will train on publicly available data and provide sources alongside its answers so agents can confirm their validity. The aim is for US spies to more easily sift through ever-growing troves of information, although the exact nature of what constitutes “public data” could spark some thorny privacy issues.

“We’ve gone from newspapers and radio, to newspapers and television, to newspapers and cable television, to basic internet, to big data, and it just keeps going,” Randy Nixon, the CIA’s director of Open Source Enterprise, said in an interview with Bloomberg. “We have to find the needles in the needle field.” Nixon’s division plans to distribute the AI tool to US intelligence agencies “soon.””.

The CIA confirmed that it’s developing an AI chatbot for all 18 US intelligence agencies to quickly parse troves of ‘publicly available’ data.

The researchers tested their algorithm on a replica of a US Army combat ground vehicle and found it was 99% effective in preventing a malicious attack.

Australian researchers have developed an artificial intelligence algorithm to detect and stop a cyberattack on a military robot in seconds.

The research was conducted by Professor Anthony Finn from the University of South Australia (UniSA) and Dr Fendy Santoso from Charles Sturt University in collaboration with the US Army Futures Command. They simulated a MitM attack on a GVT-BOT ground vehicle and trained its operating system to respond to it, according to the press release.

Australian researchers have designed an algorithm that can intercept a man-in-the-middle (MitM) cyberattack on an unmanned military robot and shut it down in seconds.

In an experiment using deep learning neural networks to simulate the behavior of the human brain, artificial intelligence experts from Charles Sturt University and the University of South Australia (UniSA) trained the robot’s operating system to learn the signature of a MitM eavesdropping cyberattack. This is where attackers interrupt an existing conversation or data transfer.

The algorithm, tested in real time on a replica of a United States army combat ground vehicle, was 99% successful in preventing a malicious attack. False positive rates of less than 2% validated the system, demonstrating its effectiveness.

Summary: Unveiling the neurological enigma of traumatic memory formation, researchers harnessed innovative optical and machine-learning methodologies to decode the brain’s neuronal networks engaged during trauma memory creation.

The team identified a neural population encoding fear memory, revealing the synchronous activation and crucial role of the dorsal part of the medial prefrontal cortex (dmPFC) in associative fear memory retrieval in mice.

Groundbreaking analytical approaches, including the ‘elastic net’ machine-learning algorithm, pinpointed specific neurons and their functional connectivity within the spatial and functional fear-memory neural network.

“ The Matrix is everywhere. It is all around us. Even now in this very room. ”

So says Laurence Fishburne’s Morpheus in sci-fi classic ‘ The Matrix ’ as he offers Keanu Reeves’s Neo the choice to find out just how “deep the rabbit hole goes”.

Now, just as Neo discovered that the “life” he’d been living was little more than an algorithmic construct, scientists and philosophers are arguing that we could be stuck inside a simulation ourselves.

Researchers developed ‘HistoAge,’ an algorithm that unravels brain aging and neurodegenerative disorders.

As we age, our brains undergo structural and cellular changes influenced by intrinsic and external factors. Accelerated aging in the brain can result in an increased risk of neurodegenerative conditions, bipolar disorder, and mortality. In a bid to deeply understand how an aging brain works, researchers say they have built a powerful AI tool that can identify regions in the brain vulnerable to age-related changes.

The team used AI to develop an algorithm called ‘HistoAge,’ which predicts age at death based on the cellular composition of human brain tissue specimens with an average accuracy… More.
