This hellsite is a toxic shithole of slop and awful people, so I'm not going to bother with it anymore. Find me on Bluesky; link in bio. Bye 🙂

Really cool research!

We built an AI assistant that plays Minecraft with you.
Start building a house—it figures out what you’re doing and jumps in to help.

This assistant *wasn't* trained with RLHF. Instead, it's powered by *assistance games*, a better path forward for building AI assistants. 🧵

I wrote up a quick reference guide on multiple linear regression, including model fitting, standard errors on coefficients, and confidence and prediction intervals.

@MairiJSHill @melbourneice Congratulations Mairi! That's brilliant! 😄

✍️ Had time this week to write up a few notes on simulated annealing, a really neat algorithm that doesn't get stuck in local minima and, with patience, will converge to the *global* optimum! 📈

the problem with a policy of providing a fascist ethnostate with all the weapons it could ever want and diplomatic cover no matter what is that they will use their weapons to murder anybody and everybody with wilfully abandon. this was obvious 5 years ago and it's obvious now 👍

Adding to my blog with a post on calculating Gower's distance, a neat way of measuring similarity between mixed-type data for things like clustering or classification! 😊

I found the eclipse times in this article from @CBSNews, and added the range of times (in UTC) of the partial and totality to the #Wordzee data. You can see the dip in player activity during the eclipse before returning to normal levels! Rather neat 😎☀

I'm a data analyst at mobile game studio @maginteractive, and wondered whether we might be able to spot the April 8th #Eclipse in our player activity data... Turns out there's a pretty clear effect! 🧵

[Crispin Agar @CrispinAgar]

The graph shows the number of US players at each minute of the day in our game #Wordzee, using data from April 1st - 8th. I've normalised the y-axis because proprietary data😉. The grey lines are the 1st - 7th for reference, and the black line is the 8th, the day of the eclipse.

This. I've taken to using ChatGPT to answer questions in/about Swedish, and it's amazingly helpful!

[Josh Otten @ordinarytings]

Chat-GPT is an insanely useful tool when learning languages. Being able to ask it questions about pronunciation or other super specific stuff you are struggling with. Way better than trawling through paragraphs of SEO-clapped nonsense. It’s like having a
teacher on iMessage

[MAG Interactive @maginteractive]

For the fourth year, we have joined forces with UN’s @P4PAlliance to help raise awareness about the 🏔️ Himalayas and the endangerment of snow leopards by launching special themed events in @QuizDuel, @ruzzlegame, @wordbraingame and @WordDomGame. 🏔️ #Playing4ThePlanet

@tcarpenter216 My go-to resources for stats are StatQuest with @joshuastarmer and zedstatistics by @jeremysironpod . Both their YouTube channels have excellent videos, from beginner to advanced topics, all explained at a perfect level!

@sliippr And then you switched to theory, traitor :P

[NHS Million @NHSMillion]

We’re trying to get as many followers as Rishi Sunak so we can show the government just how many people are prepared to fight for the NHS and its staff

Please can you help by taking a few seconds to follow us and retweet this?

[Crispin Agar @CrispinAgar]

I can’t tell you what I’m looking for or else it would skew the results, but when I have sufficient data I will happily share my findings 😏 👨‍🔬📊

[Crispin Agar @CrispinAgar]

Hi twitter peeps! I need some data for a qick experiment! Can you help me by filling out the following questionnaire? There are 4 anonymous Q's and the data collected is non-personal 😅 I'd also be very grateful if you would share 🙂
