Hi! I'm Victor!
Here's a quick intro :D
These days I focus on ML/AI at Google but have been a teacher, data scientist MLE, etc.
I try to be genuine & positive so when I leave this world it's in a better state than I found it
You can likely find my other online presences on GitHub.com/MrGeislinger

Probably the biggest difference from my experience is exactly that— folks coming in with the idea of AI being something like a chatbot
To be honest, saying 'AI' over 'ML' or something more technical & specific still feels awkward coming out of my mouth

Super interested to know what this looks like now since first teaching ML & data science in 2018 (which I realize is almost *8yrs ago*!)
I haven't purposefully put together educating material since this video for pre-university students about couple years ago: youtu.be/qXMD4PyDJTA

But how does AI really work? Let's start with the basics...

In undergrad physics we had weekly 2-question quizzes instead of 'graded' homework— I thought it was the best! It gave us a quick gauge of our understanding of recent material. It was important that they were 'simple' if you had a firm understanding
I can imagine daily quizzes being even better

Story Time: I was a peripheral member of an Iranian clique during my PhD. We’d make pizza, work out, and jump the bonfire together for chaharsanbe suri. One of my friends, now a successful scientist, had been social chair for her department back in her undergrad (in Iran).

Yeah, I was only looking at WhatsApp since that's what the group uses the most
I'm reconsidering to instead focus on it being a standalone web app for the group. But going to gauge what the group thinks after experimenting with the actual 'bot internals'

Congrats!
You still need to celebrate the wins even when *wildly waves hands around* is going on

I'm learning that I probably can't add the bot directly to a group chat. So it'd have to be a 1:1 chat conversation which sorta ruins its best use case
Going to have to see if it makes sense to still keep it on just WhatsApp

This is also me to everyone outside of direct family 😅 I say better late than never!
But it could be worst— I never sent out some of our 2024 cards lol But I blame in part that our cards got lost & delayed getting to us for us to send out

No worries— we got the donuts by car (but not nearly as fun going by bike)

I've heard the reasoning goes 'something something scaling you something something'
I'm with you; this is what is usually wanted but it's also not what I find the most enjoyable

Our morning 'bike to donuts w/ the twins' plan hit a snag with the carrier getting a flat tire
But at least we got to see the field all frosted before the sun melted away

I will share what I do! (it'll be relatively simple)
I had worked on some of this a few years ago (even made a short course on Coursera lol), but embarrassingly it's been that long since touching it again 😅

When I'm not on classic mode of reverse chronological with 'Following', it's probably the 'For You' feed: bsky.app/profile/did:...

Haven't gotten access to it (yet), but been following the effort & seeing bits of the features with hungry eyes
It looks really cool & can't wait to see it more generally available!
(Feels like it could encourage more of the reason I was first interested in old Twitter)

Great to see a lot of people back, lately!
I miss Francois Challet and would love to see him back, too! 🤩
In case people are not aware: @eugenevinitsky.bsky.social and @mariaa.bsky.social have been building a researcher-friendly Bluesky client that makes it easier to avoid the anti-AI trolls.

I haven't been here for a year or so because the anti-AI bullying was too much. How does one get an AI/ML focused feed here nowadays and stay away from the hateful people?

Yesterday I was looking into integrating a simple chat bot on a small WhatsApp group for a lil org I'm in. The idea is to make it so the group can ping the bot about details of upcoming events
Anyone have experience or advice to look out for? Been a while since trying to build anything w/ WhatsApp

Really great to see @howard.fm trying to be here again— they have so much great knowledge & insight in practical ML/AI. Definitely someone to follow if you're not already
This seems reflective of more folks in the field being active on here. Please keep supporting to encourage more folks again ♥️

It's great to see you giving it another go ♥️
I remember when it became too much & you decided it wasn't worth it. Frankly it was disappointing knowing you weren't going to contribute on here but also completely understandable
I think (and hope) it'll be better this time
