While we are talking about the structure of the cosmos, have a look at this fantastic logarithmic map of the universe by Gott and Juric:
https://www.astro.princeton.edu/universe/

The map itself is 639 x 4212, which Mastodon doesn't support. But here is the part with really large distances on it – 10 to 10,000 megaparsecs – that shows the Great Wall.

Four years after Japanese billionaire Yusaku Maezawa said he'd lead a crew of artists and other creative types on a Starship trip around the moon, the crew members have finally been named. Will these folks fly in a year's time, or will it be more like another four years? Or never?

Had a fun quick interview with #MLStreetTalk at #NeurIPS! Check it out if you're interested in some of my thoughts on language, grounding, and the state of the field!

A nice write-up of my #NeurIPS paper by GT Communications staff:

"An unexpected discovery by Mark Riedl & his collaborators"

TL;DR: We modified an RL system to make it more explainable. It made the base RL work better.

(Also I appreciate that they used an image that makes me look younger)

the modes of oscillation for a sphere- the spherical harmonics. (closely related to the shapes of atomic orbitals)

Babe, wake up, a new #JWST image just dropped.

Light from the protostar L1527 escapes above and below an edge-on protoplanetary disk (the dark line at the center of the image), creating an hourglass shape. This illuminates the cavities carved as ejected material from the star collides with the surrounding, dusty nebula.

Dust scatters shorter wavelengths of light, so blue areas are where the dust is thinner and orange areas are where the dust is more dense.

This week, the world’s human #population is expected to reach 8B. About 109B people have lived and died. Each grain of sand represents 10M.

I love how my mastodon timeline now looks like my well curated twitter timeline used to. :D

now the only thing i need is the frequency filter. what's that? glad you didn't ask! the frequency filter is a slider that live-filters toots of high frequency posters in the timeline, to reveal only the toots of people who post less than once a week or so.

this way i can, with the help of a simple slider, alternate between reading a live, short term feed, and a retained, long term feed.

Look who's here on sigmoid.social! @laramar and @rajammanabrolu!

Lara Martin and Raj Ammanabrolu will both be on the job market (separately).

❖ Lara works has the prestigious CI Fellowship and is a postdoc at UPenn and works on neuro-symbolic AI for story generation and interactive storytelling.

❖ Raj is a postdoc at AI2 and works on NLP and reinforcement learning. He has SOTA on interactive text world environments.

You should definitely give them jobs.

AI-generated high-five!
