REDUCE GPS DATA ERROR ON ANDROID WITH KALMAN FILTER AND ACCELEROMETER
One day I got a cool task to improve the accuracy of positioning and distance calculating based on GPS data on Android devices. After some research, I found that different GPS-receivers produce different errors. The accuracy of the GPS point can be influenced by buildings, big trees, various weather conditions and by the satellites configuration. GPS gives nice values to detect one-time position, but its accuracy is not enough when using stream of GPS data to calculate distance and cost of taxi-services. The received data is not suitable due to the error accumulation. The error accumulation may lead to 400% of overpricing and to customers dissatisfaction as the result.

Two centuries later, the disease named for Parkinson is still a puzzle. It is now known that the telltale external symptoms — rigidity, slow movement, a resting tremor — result from a loss of dopamine-rich neurons in a region of the brain called the substantia nigra. But the complete network of steps leading to this cell death is still vague, and the underlying causes remain one of medicine’s great mysteries.

Technically, dividing by zero is a division operation where the divisor or denominator is zero. We can express this division formally as as a/0 {a over zero} where a is the dividend (numerator). For mathematics, the expression a/0 has no meaning. Source: medium.com
ARTIFICIAL INTELLIGENCE CAN DIAGNOSE PROSTATE CANCER AS WELL AS A PATHOLOGIST
Chinese researchers have developed an artificial intelligence system which can diagnose cancerous prostate samples as accurately as any pathologist, holding out the possibility of streamlining and eliminating variation in the process of cancer diagnosis. Source: sciencebusiness.net
YOUR SPEECH IS PACKED WITH MISUNDERSTOOD, UNCONSCIOUS MESSAGES
Imagine standing up to give a speech in front of a critical audience. As you do your best to wax eloquent, someone in the room uses a clicker to conspicuously count your every stumble, hesitation, um and uh; once you’ve finished, this person loudly announces how many of these blemishes have marred your presentation.

ALIBABA CLOUD CLIMBS TO TOP 5
Last week Chinese eCommerce giant Alibaba announced its Q3 earnings. Cloud revenue was $553 million, an impressive 104 percent year-over-year increase. That comes out to a run rate in the range of $2.2 billion, well behind Google which announced it is pulling in a billion dollars a quarter and still buried behind the market leaders all of whom reported around $4 billion+ a quarter.

MIT, Harvard, and LBNL physicists have discovered a new quantum electronic material, the “kagome metal,” whose atomic structure resembles a Japanese basketweaving pattern and exhibits exotic, quantum behavior. Source: mit.edu
SPLASH OF COLOR: INSTANCE SEGMENTATION WITH MASK R-CNN AND TENSORFLOW
Back in November, we open-sourced our implementation of Mask R-CNN, and since then it’s been forked 1400 times, used in a lot of projects, and improved upon by many generous contributors. We received a lot of questions as well, so in this post I’ll explain how the model works and show how to use it in a real application. Source: matterport.com
MACHINE LEARNING SPOTS TREASURE TROVE OF ELUSIVE VIRUSES
Researchers have used artificial intelligence (AI) to discover nearly 6,000 previously unknown species of virus. The work, presented on 15 March at a meeting organized by the US Department of Energy (DOE), illustrates an emerging tool for exploring the enormous, largely unknown diversity of viruses on Earth.

THIS $10,000 3D-PRINTED ELECTRIC CAR WILL BE ON THE MARKET IN 1 YEAR
The cars top out at 70 kilometers per hour (a little under 45 MPH) and have a range of 150 kilometers (just over 90 miles). A designer for XEV told South China Morning Post that China was the biggest market for their cars, and the company is in talks to set up a production line on the mainland.
