Guess the AI Jukebox artist
AI Jukebox is a fascinating project from OpenAI that uses cutting-edge neural neworks to perform all sorts of musical magic -- it can take a clip of a song and continue it in a new way, sing text lyrics in any artist's voice, make a song sound like it's being sung by someone else. My favorite? Tell it to generate music by an artist without any other info, and it will produce a gibberish song with nonsense lyrics... that still sounds 100% real and just like the actual singer or band with their unique style.
You can hear instruments, melodies, sometimes an audience, the breathing of the lead singer -- but the whole thing is generated completely from scratch by the AI, not with samples or digital sounds. It's not flawless -- some of the songs ramble, with glitchy effects or a mutating voice. But these just add to the vibe, like it's from a dream or a parallel universe.
I went through their database to find the best examples of these tracks from the most famous artists, then turned them into an audio quiz on Sporcle -- complete with AI-generated art of the artists I made to serve as hints in the second round. How many of the artists can you name? [more inside]
On the internet, nobody knows you're a bot
I used thousands of New Yorker cartoon contest caption submissions to classify about 100 cartoons into nineteen categories, and trained a neural network to generate new captions for each category. Some of them are kind of funny. [more inside]
J. R. "Bob" Dobbs Memorial Inverse Hessian Multiplication
Inverse hessian multiplication in linear gradient time has been an open problem in neural networks since Reagan was president or so. I believe I have a successful attack on the problem and like an idiot I posted it on a blog instead of like a journal or something. Done with Something Awful goons yelling at me the whole while
lexiconjure
A twitter bot that uses machine learning to define invented words, posting truncated definitions on Twitter and complete ones on Tumblr. Tweet @lexiconjure a made-up word, and it'll define it for you. [more inside]
Neural Networks Translate Images to Poetry
Neuralsnap generates an image caption using a model I trained (convolutional and recurrent neural networks), then uses another character-level recurrent neural net that I trained on ~40 MB of poetry to expand the caption into a poem. (In this example, generated from a Rothko painting, the red text is the direct image caption, and the rest is the poetic expansion.) [more inside]
