Using Neural Networks to Identify Blurred Faces

Neural networks are good at identifying faces, even if they're blurry:

In a paper released earlier this month, researchers at UT Austin and Cornell University demonstrate that faces and objects obscured by blurring, pixelation, and a recently-proposed privacy system called P3 can be successfully identified by a neural network trained on image datasets­ -- in some cases at a more consistent rate than humans.

"We argue that humans may no longer be the 'gold standard' for extracting information from visual data," the researchers write. "Recent advances in machine learning based on artificial neural networks have led to dramatic improvements in the state of the art for automated image recognition. Trained machine learning models now outperform humans on tasks such as object recognition and determining the geographic location of an image."

Friday Squid Blogging: Space Kraken

A Lego model of a giant space kraken destroying a Destroyer from Star Wars.

As usual, you can also use this squid post to talk about the security stories in the news that I haven't covered.

Tesla Model S Hack

Impressive remote hack of the Tesla Model S.

Details. Video.

The vulnerability has been fixed.

Remember, a modern car isn't an automobile with a computer in it. It's a computer with four wheels and an engine. Actually, it's a distributed 20-400-computer system with four wheels and an engine.

More on the Equities Debate

This is an interesting back-and-forth: initial post by Dave Aitel and Matt Tait, a reply by Mailyn Filder, a short reply by Aitel, and a reply to the reply by Filder.

Friday Squid Blogging: Giant Squid on Japanese Television

I got this video from PZ Myers's blog. I know absolutely nothing about it.
