Very good to be reminded of this. The funny thing is that there was a brief time right before deep learning took over computer vision research, but after people realized the implications of big data, where it looked like the future could be

Yes, all of them. Oculus Rift, HTC Vive, Google Cardboard, etc. They show a different view to each eye.

There appears to still be active research about mechanisms that explain the historical data but here's a clearly written article [1] discussing a few factors such as: variation in solar radiation due to variation in Earth's orbit,

Interesting analysis, but after reading the FAQ at the bottom, it rests upon quite a few important hidden assumptions. For example: >However if there is any hope of finding life on other planets, there must be a huge number of planets w

The classifiers were probably trained independently and are running independently here as well, not in a hierarchical fashion. Another way of saying this is that while the tiger training data consisted completely of tigers (for positive tra

Good points. Just to clarify in case folks take your experience in 2005 as the rule, while certainly not as widespread as today, ML was definitely being offered at various universities in the late 90s and early 2000s: for example, the textb

This is some very cool research, though many may be surprised to learn that it is an IJCV journal article from 2007, based on a conference paper from NIPS 2005. Source: http://www.cs.cornell.edu/%7Easaxena/learningdepth

Regarding the synthesized singing that begins 10 minutes into the video [1], I had long ago read that the reason HAL sings "Daisy, Daisy..." in the film 2001: A Space Odyssey is that Arthur C. Clarke had seen a demonstration of a

The interesting data here aren't the news articles themselves, but the news-browsing history of 20 million people over a 4 month period. To answer your first question, though, according to the official description of the dataset [1], &

It's true, but it's such a shame. I still remember the day metacritic switched away from their original design [1] where every movie currently in theaters was in that single column on the left hand side. You visited one page, you

The most interesting bit to me was learning why the mission involves orbiting Jupiter rather than orbiting Europa directly. Though the text doesn't make it clear, the video explains (starting at 0:59) that directly orbiting Europa wou

The end user never sees the raw video in this case so that's not a requirement -- they're generating lots of synthetic stereoscopic views for the user by post-processing the video and accounting for depth. I'll be interested

Right, after playing through a whole song on the web, my first reaction when I saw that there was an app version available was: Oh, that's brilliant, the web app (which I thought was the end of the story) is actually an interactive dem

Interesting. There must be something unique about the market for apps in Norway as I managed to hit a similar milestone [1] (outselling Angry Birds in Norway for one day) in 2011. [1] http://trimensional.com/blog/2011&

Thank you for the link, that was a wonderful essay. And you've just reminded me that I've had an old used copy of Clarke's "Profiles of the Future" (the apparent source of this article) sitting on a shelf in the nex

The distance threshold was determined by hand on a per scene basis, and then we find connected components in the graph of neighboring 3D points, so it's a bit of a hack, but there are two important things to note. First, we can get aw

I had a similar reaction. In addition to the article's assumption that the consumers and producers of audio are distinct groups with no overlap, there is the assumption that humans will be the only ones listening (rather than computer
