WaveGrad by @cnxhk et al is a clever new neural net for generating speech. It starts with random noise, and iteratively denoises, essentially hallucinating a voice in the noise. Listen to the voice emerge, as the number of iterations increases with time 🔉
The WaveGrad paper: arxiv.org/abs/2009.00713
the video shows mel-spectrogram features that are used to guide the denoising and specify the speech to produce. These could be the output of a text-to-speech system

a simple way to fingerprint a language-

take a bunch of text in the language, and every time one character occurs after another, connect them with a line from the left side to the right side

here is English after 70 million characters Image
some more languages Image
notice that similar languages look similar Image

an app where kids can view their lego models as if they were real and full scale

I made these with Stable Diffusion - pushing the photo away from 'lego' and towards 'photograph'

we can now create infinite zooming fractals using Stable Diffusion's machine learning models

for this one I entered "scottish coastline satellite image"
for this one I put "path going into forest"
"new york city buildings looking down from a distance"

give each pixel a random Pokemon type, and then battle pixels against their neighbors, updating each pixel with the winning type (using the Pokemon type chart)

we quickly see areas of fire > water > grass > fire, electric sweeping over, ground frontiers taking over etc etc
this is a cellular automaton, inspired by the rock-paper-scissors automaton-
in this version, pixels only battle against the four neighbors to the north, south, east, and west (and not in the four corners)

no matter how chaotic and unstable the orbits of these three gravitational bodies are, their centre of gravity (centroid of the triangle) always remains stationary and fixed in space
in general the centre of gravity moves at a constant velocity, but I ensured this velocity was zero for these simulations

did you guess what shape is hidden in the circumference of this wire?
equation of the wire Image
or, more succinctly in @WolframResearch #Wolfram language:
RotationTransform[ t, {0, 1, 0}][
Join[ Entity["PopularCurve", "PiCurve"]["ParametricEquations"][t] /
500 + {3, 0}, {0}]]
