Nvidia’s Jetson Nano Puts AI In The Palm Of Your Hand

Posted by in category: robotics/AI

We (TIRIAS Research) recently had an opportunity to evaluate the latest Jetson platform from Nvidia. At just 45mm x 70mm the Jetson Nano is the smallest Artificial Intelligence (AI) platform form factor Nvidia has produced to date. The Jetson Nano is powered by the Tegra X1 SoC, which features quad 1.43 GHz Cortex-A57 CPU cores and the 128-core Maxwell GPU. The Jetson Nano also uses the same Jetpack Software Development Kit (SDK) as the other Jetson platforms, the TX2 and AGX Xavier, allowing for cross platform development. For only $99, plus a little extra for accessories, the Jetson Nano is an amazing platform.

In addition to the Tegra X1 SoC, the Nano developer kit comes configured with 4GB of LPDDR4 memory and plenty on I/O options, including a MIPI CSI connector, four USB 3.0 Type-A ports, one USB 2.0 Micro-B, one gigabit ethernet port, and 40 GPIO pins. The Nano is capable of driving dual displays through single DisplayPort and HDMI ports, it has an microSD card slot for storage, and a somewhat hidden M.2 Key E connection for expansion modules/daughter cards for optional functions like wireless connectivity. The Jetson Nano developer kit comes with a sizable heatsink for passive cooling, but has holes drilled for add-on fans. For our evaluation, we used a Noctua NF-A4x20 5V PWM fan and a Raspberry Pi MIPI Camera Module v2 from RS Components and Allied Electronics.

For development software, the Nano runs an Ubuntu Linux OS and uses the Jetpack SDK, which supports Nvidia’s CUDA developer environment, as well as other common AI frameworks, such as TensorRT, VisionWorks, and OpenCV.

Team develops robust molecular propeller for unidirectional rotations

Posted by in categories: biological, particle physics

A team of scientists from Ohio University, Argonne National Laboratory, Universitié de Toulouse in France and Nara Institute of Science and Technology in Japan led by Ohio Professor of Physics Saw-Wai Hla and Prof. Gwenael Rapenne from Toulouse developed a molecular propeller that enables unidirectional rotations on a material surface when energized.

In nature, molecule propellers are vital in many biological applications ranging from the swimming bacteria to intracellular transport, but synthetic molecular propellers, like what has been developed, are able to operate in harsher environments and under a precise control. This new development is a multiple component molecular specially designed to operate on solid surfaces. This tiny propeller is composed of three components; a ratchet shape molecular gear as a base, a tri-blade propeller, and a ruthenium atom acting as an atomic ball bearing that connects the two. The size of the propeller is only about 2 nanometers (nm) wide and 1 nm tall.

“What is special about our propeller is its multi-component design that becomes chiral on the gold crystal surface, i.e. it forms right- or left-tilted gears,” said Hla. “This chirality dictates the rotational direction when energized.”

Juvenescence Secures $100M for Rejuvenative Therapies

Posted by in categories: biotech/medical, life extension

It seems that billionaire biotech investor Jim Mellon is the flavor of the month as he continues the drive to create a rejuvenation biotech industry. Jim and his colleagues at Juvenescence have announced that they have secured another $100M for the company, and it will be used to invest and support the growth of promising biotech companies working in this field.

Juvenescence has a varied investment portfolio of companies that range in potential usefulness, depending on your point of view, and they mostly favor the more traditional small molecule drug approach. There are a few companies that are of particular interest.

An Overview of Python’s Datatable package

Posted by in categories: information science, robotics/AI

Modern machine learning applications need to process a humongous amount of data and generate multiple features. Python’s datatable module was created to address this issue. It is a toolkit for performing big data (up to 100GB) operations on a single-node machine, at the maximum possible speed.

Brain scans could help personalize treatment for people who are depressed or suicidal

Posted by in categories: biotech/medical, habitats, neuroscience

By his late 20s, Moe had attained the young adult dream. A technology job paid for his studio apartment just blocks from the beach in Santa Barbara, California. Leisure time was crowded with close friends and hobbies, such as playing the guitar. He had even earned his pilot’s license. “There was nothing I could have complained about,” he says.

Yet Moe soon began a slide he couldn’t control. Insomnia struck, along with panic attacks. As the mild depression he’d experienced since childhood deepened, Moe’s life collapsed. He lost his job, abandoned his interests, and withdrew from his friends. “I lost the emotions that made me feel human,” Moe says. (He asked that this story not use his full name.)

Although many people with depression respond well to treatment, Moe wasn’t one of them. Now 37, he has tried antidepressant drugs and cycled through years of therapy. Moe has never attempted suicide, but he falls into a high-risk group: Though most people with depression don’t die by suicide, about 30% of those who don’t respond to multiple antidepressant drugs or therapy make at least one attempt. Moe was desperate for relief and fearful for his future. So when he heard about a clinical trial testing a new approach to treating depression at Stanford University in Palo Alto, California, near his home, he signed up.

You Can Now Rent Tesla Solar Panels for Crazy Cheap

Posted by in category: sustainability

Now, the company is trying yet another approach, launching a new program that lets homeowners rent Tesla solar panels for as little as $50 per month plus tax.

To rent Tesla’s solar panels, you must own a home in Arizona, California, Connecticut, Massachusetts, New Jersey, or New Mexico and be a customer of one of 20 listed utility companies.

The rental rate varies by state and size of the system — small, medium, or large — but in all instances, the single monthly fee is all-encompassing, covering everything from the hardware and installation to maintenance and support.

Fraud Detection Using Random Forest, Neural Autoencoder, and Isolation Forest Techniques

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

  • Fraud detection techniques mostly stem from the anomaly detection branch of data science.
  • If the dataset has sufficient number of fraud examples, supervised machine learning algorithms for classification like random forest, logistic regression can be used for fraud detection.
  • If the dataset has no fraud examples, we can use either the outlier detection approach using isolation forest technique or anomaly detection using the neural autoencoder.
  • After the machine learning model has been trained, it’s evaluated on the test set using metrics such as sensitivity and specificity, or Cohen’s Kappa.

With global credit card fraud loss on the rise, it is important for banks, as well as e-commerce companies, to be able to detect fraudulent transactions (before they are completed).

According to the Nilson Report, a publication covering the card and mobile payment industry, global card fraud losses amounted to $22.8 billion in 2016, an increase of 4.4% over 2015. This confirms the importance of the early detection of fraud in credit card transactions.
