Selfie 101

What's your take on this guy? Sinister, serious, direct, intense, take your pick as the human face both reveals and conceals our innermost feelings 24/7 to the outside world. Up to now, this eval was done by us rubes, now there's a new evaluator on the scene that does it better than we can.

To whit ...

Russian researchers from HSE University and Open University for the Humanities and Economics have demonstrated that artificial intelligence is able to infer people's personality from 'selfie' photographs better than human raters do. Conscientiousness emerged to be more easily recognizable than the other four traits. Personality predictions based on female faces appeared to be more reliable than those for male faces. The technology can be used to find the 'best matches' in customer service, dating or online tutoring.

The article, "Assessing the Big Five personality traits using real-life static facial images," will be published on May 22 in Scientific Reports.

It's just a matter of time ...

Things get crazed in the center of our galaxy.

The center of our Galaxy hosts a supermassive black hole of 4 million times the mass of the Sun. A great number of stars spin around it at very high speed. The UCLA Galactic Center Group discovered another class of objects orbiting the black hole: the G objects. These peculiar objects look like gas clouds but behave like stars. G objects are likely stars that are hidden in a thick envelope of gas and dust. They may have formed as the result of the merger of a pair of stars. This animation is a visualization of the orbital motion of G objects and stars in the Galactic Center. The G objects are shown in magenta, young stars in green and old stars in orange. The orbits are based on the Keck data obtained between 1995 and 2019. 

It gets better.

Intensity +  without a doubt. :)

HK ... We hardly knew ye.

I have a close friend who's a native Hong Konger, a guy who loves his city beyond words and who now inwardly weeps as to what is happening to her as China begins to extinguish a truly international environment that benefitted the world in so many ways.

Read the detailed NYTimes piece, it's the right thing to do.

HK ... we hardly knew ye ... indeed.

3 into 2

Creativity to the max, this time layering 3 dimensions into 2, in this case, using time to enable code to correct errors in quantum systems at a rate thought impossible until now.

3 into 2 without question. :)

The last piece ...

AI, no longer controlled by us rubes in many disciplines given the fact real-time analysis of incoming data requires software able to update itself in real-time, cannot be done by humans in any way, shape or fashion, could not process symbolic math, until now.

But a problem remained.

Soon, he and Lample plan to feed mathematical expressions into their networks and trace the way the program responds to small changes in the expressions. Mapping how changes in the input trigger changes in the output might help expose how the neural nets operate.

Zaremba sees that kind of understanding as a potential step toward teaching neural nets to reason and to actually understand the questions they’re answering. “It’s easy in math to move the needle and see how well [the neural network] works if expressions are becoming different. We might truly learn the reasoning, instead of just the answer,” he said. “The results would be quite powerful.”

An understatement to say the least.

Read the rest of the excellent Quanta's Magazine piece to see why the last piece ... of developing truly intelligent AI is now in place to enable this tech to become ... truly intelligent.

A treaty to live by without question ...

The Artemis Accords, NASA's take on how man should cooperate in space, is similar in scope to the Antarctic Treaty System as Antarctica is also a hostile place requiring everybody to play nice as both environments can kill in an instant thus requiring everyone to work together to limit that grim possibility as much as possible.

A treaty to live by without question ...

My take without question: :)

Boston Tea Party, among significant others ...
As for Calvin's non-answer... AWESOME!!! :)

The hidden view ...

All of humanity resides on top of huge, invisible plates, constantly moving due to the internal heat engine of earth.

Researchers want to simulate the behaviour of the mantle.

This solid rock layer, which resides between the planet's core and crust, moves very slowly over time - roughly at the speed that a fingernail grows.

The scientists will investigate its complex pattern of upwellings and downwellings.

The team hopes its new circulation models will provide fresh insights into how the mantle has influenced the Earth's surface over hundreds of millions of years.

The impact of the constant motion of these plates goes beyond imagination.

A key target is to understand the upwellings that ultimately result in "hotspots" at the Earth's surface - the places where there have been colossal outpourings of lava and gas through geologic history.

"These are what we call the Large Igneous Provinces, or LIPs," explained Prof Davies.

"There hasn't been anything like this since the Columbia River flood basalts in North America just over 10 million years ago. So, they're rare. And thank goodness, because they can be absolutely catastrophic.

"The Siberian Traps which cover a large part of west Siberia match up with the largest extinction on Earth. A lot of the great extinction events are linked to these LIPs."

Seen below is a Cardiff University graphic detailing the 
heat distribution of earth driving the motion of plate since the beginning of time.

The hidden view indeed.
