I'm really excited to share that our paper "Selective Reincarnation in MARL" was chosen for an oral presentation at the Reincarnating RL workshop at ICLR 2023 🇷🇼

Feeling very grateful to be a small part of this incredible team at InstaDeep Ltd (in gorgeous Cape Town 🇿🇦)

Earlier today Elon Musk said that my ban was temporary, 45 min later he denied my appeal to reinstate my account and confirmed that I am *permanently* banned. The email I just received says the decision cannot be reversed.
I have never once violated Twitters rules or terms of service. I’ve never had a single tweet flagged, my account was permanently banned with no warning and with no reason, after I reached out to Musk for comment.

Some Mastodon thoughts, for bird-site expats (which include myself). I'm aggregating these from posts I've boosted before, so little of this is my own brain.

- There's no algorithm here. That means favoriting/liking doesn't do anything except communicate approval to the OP and others (which is still nice!).

- No algorithm means boosting ("retweeting") is the true method to increase a post's visibility. Do that more than you did on birdsite.

- There's no post-quoting here, and that's by design. Look at quote-tweets on the birdsite; it's a feature primarily used for toxicity.

- There's no direct word-search here either; that means you want to use hashtags to make posts more searchable. This is also intended, since word-searching posts was often used to harass/stalk on the birdsite and elsewhere, so that was left by the wayside here. This also means hashtags are much more a thing here than any of the algorithm-powered sites.

- It's encouraged to put in text descriptions when you post images; a lot of Mastodon users use screen-readers due to various disabilities, and getting an image description read out loud helps them immensely.

- Speaking of screen-readers: using capitalization in your hashtags allows the screen-readers to read them more easily, especially if you're smashing multiple words together. #rockmusic = unreadable. #RockMusic = readable.

- The best way to make threads is to make set your first post as public, but "unlist" all of your replies. This prevents your whole thread from clogging up feeds.

- Content Warnings should be used more liberally here. If you haven't gotten the impression yet, much of Mastodon was built and populated by marginalized groups who were harassed/bullied off of other platforms. This is the culture they built, to respect each other's mental health. It's not a rule, but it's well-appreciated.

- Consider chipping a few bucks towards whomever runs the server you're on; the strain is real, and most server admins were likely paying out of pocket before so don't have an existing donation base. The growth here has been extremely fast, and that means money's needed.

- DMs are just posts with privacy settings. So if you @ someone in a DM, you pull them into the thread. That could be embarrassing.

- Also, no, DMs aren't end-to-end encrypted, but they aren't on Twitter either. Don't use either if you want true privacy.

- Including your Mastodon handle in your birdsite profile will help people find you here; there's a tool (pruvisto.org/debirdify/ is one of them that's used) people can use to pull Mastodon handles from Twitter profile.

- Use the blocking and reporting features liberally, if needed. This should go without saying, but they work, and work well!

- If there's an entire Mastodon server you don't want to hear from, you can block the whole thing too.

- Preferences -> Appearance -> "Slow Mode": this can make larger "Local" feeds and any "Federated" feed much more readable.

I'll reply with some more as I see them, or reply here too. I've only been here 4 days but I'm loving it so far.

Do it again😃.

Hello! 👋

Usually a lurker, but excited to test out this new space.

I just finished my MSc at the Uni of Edinburgh, where I looked at Discrete Gradient Estimation in the context of MADDPG. I wrote a blog post about my work here: https://agents.inf.ed.ac.uk/blog/revisiting-gumbel-softmax-maddpg/

Next year, I'll be working as a Junior Research Engineer at InstaDeep. I'll be contributing to their open-source MARL library, Mava: https://github.com/instadeepai/Mava

:)
