Astronomy class inspires students

The Lamar High School astronomy class, taught by Mr. Jeff Flint, takes their learning beyond the circular planetarium of their classroom and out to the back of the school to look through a telescope at different planets and stars during their astronomy nights.

The first one of the semester was held on Feb. 18 at 7 p.m. Students looked through telescopes at Jupiter and the Orion Nebula.

Approximately eight times throughout the semester Mr. Flint hosts an astronomy night where students can look at different objects in the night sky through two different telescopes. His astronomy students are required to attend two nights.

Most of the time a classroom is rows of desks and four walls. But sometimes, a classroom is the entire night sky.

That astronomy night was the first time senior Rodrigo Chavez and junior Paige Ybarra had ever used a telescope.

"I was kind of confused at first on where to put my eye and how to move the telescope around," Ybarra said.

Both Ybarra and Chavez were surprised by the amount of detail that was shown through the telescope.

"It's better to look at the stars in person than in pictures," Chavez said. "It makes it clearer."

Ybarra agreed. "I was able to understand how they actually looked instead of just seeing a bright little dot."

Flint hosts the astronomy nights because it "allows student to see objects in real life versus the internet where it doesn't really have a personal connection. I like for them to look at the object through one telescope and then we use the camera on the other telescope to let them see the full detail."

Facebook artificial intelligence team serves up 20 tasks

14 hours ago by Nancy Owano

In August last year, Daniela Hernandez wrote in Wired about Yann LeCun, director of AI Research at Facebook. His interests include machine learning, audio, video, image, and text understanding, optimization, computer architecture and software for AI.

"The IEEE Computational Intelligence Society just gave him its prestigious Neural Network Pioneer Award, in honor of his work on deep learning," she wrote, "a form of artificial intelligence meant to more closely mimic the human brain. And, perhaps most of all, deep learning has suddenly spread across the commercial tech world, from Google to Microsoft to Baidu to Twitter, just a few years after most AI researchers openly scoffed at it." Hernandez wrote about their interest in convolutional neural networks, to build services that can automatically understand natural language and recognize images. In 2015, it is obvious that the keen interest in where to take AI continues, and an AI/ deep learning community is working to improve the technology. Facebook is taking on the challenge of turning its AI lab into a world-class research outfit.

This week, Jacob Aron in New Scientist reported how researchers at Facebook's AI lab in New York believe that a test of simple questions can help design machines that think like people. "Towards AI-Complete Question Answering: A Set of Prerequisite Toy Tasks" is a paper by a Facebook AI Research team, Jason Weston, Antoine Bordes, Sumit Chopra and Tomas Mikolov. The paper was posted on the arXiv server. "One long-term goal of machine learning research is to produce methods that are applicable to reasoning and natural language, in particular building an intelligent dialogue agent. To measure progress towards that goal, we argue for the usefulness of a set of proxy tasks that evaluate reading comprehension via question answering."

In remarks about the paper, New Scientist ran a crosshead of "AI plays 20 questions," as Facebook created 20 tasks, which get progressively harder. "The team says any potential AI must pass all of them if it is ever to develop true intelligence."

The AI team in their paper wrote that "We developed a set of tasks that we believe are a prerequisite to full language understanding and reasoning, and presented some interesting models for solving some of them. While any learner that can solve these tasks is not necessarily close to solving AI, we believe if a learner fails on any of our tasks it exposes it is definitely not going to solve AI."

Their tasks measure understanding in ways such as whether a system can answer questions via chaining facts, simple induction, deduction and more. "The tasks are designed to be prerequisites for any system that aims to be capable of conversing with a human."

New Scientist also commented that "Facebook is looking for more sophisticated ways to filter your news feed. Aron quoted LeCun, who said, "People have a limited amount of time to spend on Facebook, so we have to curate that somehow," and, he added, "For that you need to understand content and you need to understand people."

In the longer term, Facebook also wants to create a digital assistant that can handle a real dialogue with humans, said New Scientist.

Chappie: Not much intelligence here, artificial or otherwise

Directed by Neill Blomkamp and starring Hugh Jackman and Dev Patel, the science fiction film "Chappie" follows a robots journey to becoming his own man. (Sony Pictures)

In Chappie, a dystopian robot thriller from South African director Neill Blomkamp (Elysium), were introduced to an awkwardly stiff humanoid with something funny-looking sticking out of his head.

And thats just Hugh Jackman, who, along with a ridiculous mullet, plays the movies wooden, one-dimensional villain. The real automaton hero a rabbit-eared police droid that develops artificial intelligence and a streetwise swagger after being adopted by a gang of Johannesburg thugs is Chappie (South African slang for young man). As voiced by Blomkamp regular Sharlto Copley, Chappie is far more human than even his human nemesis Vincent, a muscle-bound soldier-turned-robot-designer who stomps through every scene like one of his automated combat troops.

In the role of a man who will stop at nothing including allowing the streets of Johannesburg to descend into chaos in order to create more demand for his product Jackman is simply painful to watch.

But not as painful as it is to contemplate how naively the film treats the concept of artificial intelligence and robotics. Co-written by Blomkamp with his District 9 writing partner Terri Tatchell, and set in 2016 thats right, one short year from now, in a world thats gone straight to hell! Chappie imagines a universe in which human consciousness is capable of being uploaded to a thumb drive, and where the Internet, that repository of everything from porn to the owners manual for the space shuttle is all one needs to access the entirety of human knowledge. (Never mind that last month I couldnt find a 1987 episode of SNL that I was looking for.)

Chappie is a ball of contradiction. It takes the concept of Transcendence, crosses it with the storyline of RoboCop, and then delivers it, seemingly, to the target demographic of Short Circuit. It is, in other words, simultaneously dumb, hyperviolent and cutesy.

Why, for instance, do Chappies eyes represented by eight-bit black-and-white computer graphics that look like the screens of an old Motorola cellphone narrow cartoonishly to slits when he gets angry? Why does he even have eyes, for that matter? Okay, okay, I get the anthropomorphizing. But a scene where Chappie, who is made out of bullet-resistent titanium, is shown getting some kind of tactile pleasure out of petting a dog is beyond illogical.

Theres more pleasure to be had from watching Chappies human caretakers, a couple of criminals called Yolandi and Ninja, who find Chappie and try to enlist him as a partner in crime. Played by non-actors Yolandi Visser and Ninja, a South African rap duo who perform as Die Antwoord (or The Answer), the antiheroic characters are the best thing about the movie, despite being largely unsympathetic (i.e.,theyre murderous thugs). They exude a raw appeal that, if not quite charm, is nonetheless highly watchable.

As Deon, the software engineer who wrote the computer code for Chappie, Dev Patel is adequate, if under-used. When hes wounded by one of Vincents walking death machines a remotely-operated war drone called the Moose the scene fails to elicit the pathos it might otherwise warrant, simply because Patel is such a cipher. As for Sigourney Weaver, who plays Vincent and Deons boss, she turns in a performance thats almost as heavy-handed as Jackmans.

Visually, Chappie has the cool and expensive look of a video game. Its adrenaline-stimulating eye candy. Despite Blomkamps efforts to make some kind of commentary about the human soul, which the auteur bolsters with his trademark social consciousness a tone of preachiness that, after three films, has worn out its welcome the movie exhibits precious little humanity.
