Take a Trippy Journey in This Machine-Generated Video

Coder Damien Henry created a 56-minute film based on one starting image and a machine learning algorithm. He trained the machine using video shot from the window of a moving train. Then he handed off that first frame and had the algorithm generate what it thought might be a "next" frame. That process repeated serially for the entire film, resulting in this beautiful, abstract train ride:

The soundtrack is Steve Reich's classic "Music for 18 Musicians," and the pairing helps create a mesmerizing atmosphere. Watching the video, you see smears of light and dark eventually form into landscapes (drawing on the algorithm's knowledge of landscapes), but those landscapes are often messy and surreal, looking like blobs in a lava lamp or perhaps a robot's low-fi idea of what a landscape might look like. Because the film includes zero editing, it is purely a product of that first frame and the machine's training. It's beautiful.

In the YouTube description, Henry wrote (in part):

The results are low resolution, blurry, and not realistic most of the time. But it resonates with the feeling I have when I travel in a train. It means that the algorithm learned the patterns needed to create this feeling. Unlike classical computer generated content, these patterns are not chosen or written by a software engineer.

In this video, nobody made explicit that the foreground should move faster than the background: thanks to Machine Learning, the algorithm figured that itself. The algorithm can find patterns that a software engineer may haven’t noticed, and is able to reproduce them in a way that would be difficult or impossible to code.

He also notes that the algorithm learns during the video's creation, which accounts for the increase in realism as the video goes on. He notes that the algorithm's learning system is updated every 20 seconds.

A Simple Trick For Figuring Out the Day of the Week For Any Given Date

People typically remember anniversaries in terms of dates and years, not days of the week. If you can’t remember whether you got married on a Saturday or Sunday, or don't know which day of the week you were born on, there’s a simple arithmetic-based math trick to help you figure out sans calendar, according to It's Okay To Be Smart host Joe Hanson.

Mathematician John Conway invented the so-called Doomsday Algorithm to calculate the day of the week for any date in history. It hinges on several sets of rules, including that a handful of certain dates always share the same day of the week, no matter what year it is. (Example: April 4, June 6, August 8, October 10, December 12, and the last day of February all fall on a Wednesday in 2018.) Using this day—called an “anchor day”—among other instructions, you can figure out, step by step, the very day of the week you’re searching for.

Why the Film You're Watching on HBO Might Not Be the Whole Movie

In the days before widescreen televisions, most of the movies you watched on VHS or on cable looked a little different than their big-screen versions. The sides of the image had to be cropped out so that you could watch a movie made for a rectangular screen on the small screen. Today, those little black bars on the top and bottom of the screen that allow you to watch the same movie scaled to any shape of screen are everywhere. But it turns out, cropping for aspect ratios is alive and well—on HBO, as YouTube film vlogger Patrick Willems explains.

In his latest video, which we spotted on Digg, Willems explains why aspect ratios matter, and how the commonly used aspect ratios can fundamentally change a movie.

Most old-school televisions have 4:3 aspect ratios, meaning movies had to be significantly cropped to fit wide-screen films on the small screen. Now, most computers and televisions use 16:9 aspect ratios, which is approximately the same as the one used for movies, typically 1.85:1, so many movies expand to fit TV screens perfectly. The catch: Some Hollywood movies are shot with even wider angles to show even more of an image at once. And even though viewers are familiar with the sight of those black bars, it seems the streaming sites are determined to limit their use, even for movies that don’t fit on a normal screen. As a result, you may only be seeing the central part of the image, not the whole thing. You could be missing characters, action, and landscape that’s happening on the far sides of the screen.

Since 1993, the Motion Picture Association of America has mandated that any film that’s been altered in a way that changes the original vision of its creators—say, to edit out swear words, adjust the run time, or to make it fit a certain screen—run with a disclaimer that says as much. That’s why before movies run on TV, they usually show a note that says something like “This film has been modified from its original version. It has been formatted to fit this screen.” But this doesn’t seem to apply to streaming.

In 2013, Netflix was accused of cropping films, too, showing wide-angle movies to fit the standard 16:9 screen instead of running the original version with black bars. The streaming giant claimed it was a mistake due to distributors sending them the cropped version, and those films would be replaced with the originals. However, as of 2015, users were still complaining of the problem. According to Willems, it’s a problem that still plagues not just HBO, but Starz and Hulu, too, and there isn’t any clear rationale for it other than that perhaps people don’t like looking at black bars. But frankly, that seems better than seeing a version of a film that the director never intended.
