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.

New Hand-Tracking Algorithm Could Be a Big Step in Sign Language Recognition

Posted by in categories: information science, mobile phones, robotics/AI

Several companies, like SignAll and Kintrans, have created hand-tracking software that tries, with little success so far, to allow the millions of people that use sign language and an app to easily communicate with anyone.

Now, a new hand-tracking algorithm from Google’s AI labs might be a big step in making this ambitious software everything it originally promised.

This startup says they can convert your gas car into an electric one for just $9,500

Posted by in categories: sustainability, transportation

With more electric cars on the road and the negative environmental impact of traditional vehicle emissions on the forefront of many minds, some may struggle with their choice to drive a car with a standard combustion engine.

But what if you could just “convert” your car into an electric one?

French startup Transition-One says it can do it for only $9,500 — in fact, in France, you also get a subsidy for a converted car so it actually only works out to around $5,600.

Ranging in size from the experimental Mini Bee , a 250kg technology demonstration spacecraft, through the Honey Bee, capable of capturing a 10m asteroid and extracting its resources, to the Queen Bee, capable of capturing a 40m asteroid for resource extraction. All use an asteroid containment system similar to that proposed for the original Asteroid Redirect Mission, optical mining for resource extraction, and a water based Omnivore™ Thruster system for propulsion. A variant called the Worker Bee, can serve as an orbital transfer vehicle, transporting items to high Earth orbits and beyond, potentially even to Mars.

Frontier AI: How far are we from artificial “general” intelligence, really?

Posted by in categories: education, Elon Musk, robotics/AI

Some call it “strong” AI, others “real” AI, “true” AI or artificial “general” intelligence (AGI)… whatever the term (and important nuances), there are few questions of greater importance than whether we are collectively in the process of developing generalized AI that can truly think like a human — possibly even at a superhuman intelligence level, with unpredictable, uncontrollable consequences.

This has been a recurring theme of science fiction for many decades, but given the dramatic progress of AI over the last few years, the debate has been flaring anew with particular intensity, with an increasingly vocal stream of media and conversations warning us that AGI (of the nefarious kind) is coming, and much sooner than we’d think. Latest example: the new documentary Do you trust this computer?, which streamed last weekend for free courtesy of Elon Musk, and features a number of respected AI experts from both academia and industry. The documentary paints an alarming picture of artificial intelligence, a “new life form” on planet earth that is about to “wrap its tentacles” around us.

Indian spacecraft launched last month is now orbiting moon

Posted by in categories: robotics/AI, space travel

NEW DELHI (AP) — An unmanned spacecraft India launched last month began orbiting the moon Tuesday as it approaches the lunar south pole to study previously discovered water deposits.

The Indian Space Research Organization said it successfully maneuvered Chandrayaan-2, the Sanskrit word for “moon craft,” into lunar orbit, nearly a month after it left Earth. The mission is led by two female scientists.

Chandrayaan will continue circling the moon in a tighter orbit until reaching a distance of about 100 kilometers (62 miles) from the moon’s surface.

NASA’s Next Martian Rover Is Almost Ready to Rock

Posted by in category: space

If there’s life on the red planet, our best hope of finding it may be this rock-hungry rover, currently in its final stages of construction (really!) at NASA’s Jet Propulsion Laboratory in Pasadena, California. Next summer, the Mars 2020 rover will be deployed to the Jezero Crater, where it will land in 2021 and spend more than a year prowling the planet’s surface.

World’s largest all-electric ferry sets sail in Denmark

Posted by in category: transportation

The world’s largest all-electric ferry completed its first voyage with passengers last week in Denmark.

The Ellen sailed between the southern Danish ports of Fynshav to Soby, on the island of Aero.

The e-ferry is capable of carrying 30 vehicles and 200 passengers and is powered by a battery “with an unprecedented capacity” of 4.3MWh, according to Swiss battery maker Lechanché which provided the system.
