Machine Learning with TensorFlow, Second Edition

#artificialintelligence

About the Technology TensorFlow, Google's library for large-scale machine learning, makes powerful ML techniques easily accessible. It simplifies often-complex computations by representing them as graphs that are mapped to machines in a cluster or to the processors of a single machine. Offering a complete ecosystem for all stages and types of machine learning, TensorFlow's end-to-end functionality empowers machine learning engineers of all skill levels to solve their problems with ML.


Using Machine Learning and Satellite Imagery for Street Address Generation

#artificialintelligence

Researchers from Facebook and MIT Labs have proposed a new methodology that uses machine learning and satellite imagery to generate street addresses in areas of the world where individual buildings don't have a unique address. The methodology divides the street addressing into two processes. The first process is segmentation. During segmentation, road pixels are identified using deep learning from 0.5 meter resolution satellite images. The second part of segmentation involves developing the road network from these identified pixels.


Stunning panorama of Mars reveals the final resting place of NASA's Opportunity rover

Daily Mail - Science & tech

A stunning panorama of Mars shows the final resting place of NASA's Opportunity. The image is a series of 354 individual pictures snapped by the rover over a 29-day period before it shutdown completely and declared'dead' by the American space agency earlier this year. The desolate Martian landscape known as Perseverance Valley was the last thing the rover saw and now serves as its graveyard. The panorama is composed of 354 individual images provided by the rover's Panoramic Camera (Pancam) from May 13 through June 10, or sols (Martian days) 5,084 through 5,111. The panorama combines images from three different Pancam filters, which admit light centered on wavelengths of 753 nanometers (near-infrared), 535 nanometers (green) and 432 nanometers (violet).


Is space on FIRE? NASA's Spitzer Telescope captures a massive collection of glowing gas and dust

Daily Mail - Science & tech

NASA's Spitzer Telescope captured an image of what looks like flames ripping through the black void of space. The picture highlights the Perseus Molecular Cloud, which is a massive collection of gas and dust that stretches over 500 light-years across. The fiery glow is a result of infrared radiation from warm dust and clusters of stars that'illuminate the surrounding clouds like the Sun lighting up a cloudy sky at sunset.' The Perseus Molecular Cloud is home to an abundance of young stars and is located on the edge of the Perseus Constellation. It contains over 10,000 solar masses of gas and dust covering an area of size by two degrees.


Star Wars-style lasers could help scientists accurately pinpoint space junk in orbit

Daily Mail - Science & tech

Star Wars-style lasers could help future space missions to accurately pinpoint the location of space junk in Earth's orbit and avoid deadly collisions. Millions of pieces of space junk are currently whizzing around the planet at around 20,000 miles per hour -- providing a threat to future rockets and space craft. However a new system based on neural networks has provided a better way to keep track of these hazardous objects with telescopes. The approach can detect debris as small as 3 feet wide and allow courses to be plotted to avoid them. Star Wars-style lasers could help future space missions to accurately pinpoint the location of space junk in Earth's orbit and avoid deadly collisions.


How AI Can Help Astronauts Stay Healthy In Space

Humans have evolved over millions of years to live on Earth. Now humans are planning long duration space missions that will require them to live in space for extended periods of time. NASA plans to send humans to an asteroid by 2025 and to Mars in the 2030s. NASA's Journey to Mars, the longest manned space mission ever, will require humans to live in space for more than three years.

NASA's Mars 2020 rover passes its driving test by showing it can move under its own weight

Daily Mail - Science & tech

NASA's Mars 2020 rover has successfully'passed its driving test' in a major mission milestone that saw it move under its own weight ahead of its launch next year. The rover will leave for Mars in July or August 2020 from the Cape Canaveral Air Force Station in Florida and will travel aboard the new Space Launch System rocket. NASA's robotic vehicle had to demonstrate it could move forwards, backwards and pirouette during the more than 10-hour marathon'driving test' on Tuesday. The next time the Mars 2020 rover drives, it will be rolling over Martian soil. The semi-autonomous vehicle will search for signs of ancient microbial life within the Jezero crater, which contains a dried up lake once filled with water.


Russian space agency reveals plans for asteroid tracking base on the MOON

Daily Mail - Science & tech

The Russian space agency Roscosmos is planning to install a nuclear-powered observatory on its future moon base to held spot deadly Earth-threatening asteroids. Establishing a permanent presence near the lunar south pole has been a priority for Roscosmos ever since NASA announced plans to return to the moon earlier this year. The base's telescopes will work in tandem with spacecraft placed in orbit around the Earth to help provide humanity with a space-rock early warning system. In addition, the lunar facility's permanent crew will be made up of robots -- with cosmonauts only visiting to handle more complicated tasks. The plans to establish an observatory on the future moon base were announced by Alexander Bloshenko, Roscosmos' Executive Director for Science and Long-Term Programs, Russian news outlets RT and TASS reported.


2019 A Space Odyssey: CIMON 2 Space Station Robot Detects the Emotions of Astronauts.

#artificialintelligence

CIMON (The Crew Interactive Mobile Companion 2) has been busy working with astronauts aboard the International Space Station. The robotic assistant is now using a tone analyzer, detecting emotions during the current voyage. CIMON made its debut on the ISS in November of this year, with Space.com's "During the experiment, CIMON successfully found and recognized Gerst's face, took photos and video, positioned itself autonomously within the Columbus module using its ultrasonic sensors, and issued instructions for Gerst to perform a student-designed experiment with crystals. Weighing about 5 kilograms (11 lbs. on Earth), the 3D-printed robot designed jointly by the German space agency DLR, Airbus, and IBM works similarly to Apple's virtual assistant Siri or Amazon's Alexa. "If CIMON is asked a question or addressed, the Watson AI firstly converts this audio signal into text, which is understood, or interpreted, by the AI," explained IBM project lead Matthias Biniok in the statement. "IBM Watson not only understands content in context, [but] it can also understand the intention behind it." There is a great video here, of Gerst conversing with CIMON, and it shows the complexity of this fantastic technology. Especially regarding the amount of relevant information that it can store and relay to astronauts, making their jobs easier. The Watson team at IBM computing only added the tone analyzer to the standard set of Watson capabilities this week. However, CIMON 2 was added as a seventh crew member on SpaceX Dragon during a resupply mission last week. In addition to updated software, the robot also got a hardware upgrade, with enhanced sensitivity on its microphones, and a more advanced sense of orientation. The German Aerospace Center and Airbus are the other crew members for this CIMON project. "IBM is using its tone analyzer technology to analyze how CIMON converses with the astronauts.
