This is a lovely visualization that allows you to play with a neural network by playing with some network parameters and watching the output. Even better, the authors write "We’ve open sourced it on GitHub with the hope that it can make neural networks a little more accessible and easier to learn. You’re free to use it in any way that follows our Apache License. And if you have any suggestions for additions or changes, please let us know."
Good article that will push your think on networks a bit. The bulk of the discussion is devoted toward convincing people that they ought to look at more than just nodes and edges "to also include flows and (as per Galloway and Thacker) protocols." This makes sense to me, and there are other network properties that should be discussed more as well (connection weights, activation functions, and more). But the author also says "networks need narrative" because "we experience life as a narrative, not as a map and certainly not as networks. A network diagram rarely represents static relations. Narrating a flow through the nodes in the network is a useful way of examining it." To me, that's a lot like saying "we need abstractions". And in a sense it comes down to being able to visualize what's happening. "Visualising algorithms is still a small fringe in the visualisation world. It is mostly academic and so far has mainly served an internal maths and computer science discourse."
For various reasons I've been looking at how to create and open sidebars, modals, and other embedded content windows. Now maybe it's true that the whole world uses mobile phones these days, but I still see desktops and laptops (not to mention tablets) as more important in the realm of online learning. And these, I think, will need to support content mixing a lot better than they do. (It reminds me of the days back in the 1980s working on my Atari computer where the main thing for me was to be able to have a split editing window so I could move content back and forth.) I keep hearing about how impossible it is but I see stuff like this drag-and-drop sidebar and I know it's not.
Good article making a point with which I am in full agreement: new technology won't save traditional media because traditional media isn't offering content people want. Note: language warning, especially at the point where they describe the quality of existing media content. Where newspapers and television could get away with very low-quality coverage (not to mention biased coverage and outright propaganda) in the days where they were the only source of content, now they have to provide much better content in order to compete. And they're not set up to do this. "Compelling voices and stories, real and raw talent, new ideas that actually serve or delight an audience, brands that have meaning and ballast; these are things that matter in the next age of media."
