    X isn't standing for freedom of speech, it's regularly censoring content for political reasons and manipulating views for advancing a fascist agenda in Europe. It also doesn't respect the law. I wish it'd be fined to the extent of the harm it causes, which would shut it down.

    French authorities have launched a politically-motivated criminal investigation into X over the alleged manipulation of its algorithm and alleged “fraudulent data extraction.” X categorically denies these allegations. This investigation, instigated by French politician Eric

    I made a notebook with a few notes on Diffusion Models for a "tutorial" in a project-workshop yesterday. Not really an introduction, but I give some insights that I usually don't see elsewhere. Feel free to reuse. 🔗colab.research.google.com/drive/1EyqALXF… (copy from 🦋 where I'm more often)

    Research in computer vision at the moment is crazy fast. You discuss a problem with your colleagues, find shortcomings in the literature and a way to address them, flesh out a plan, and 5 days later there are already 2 papers appearing on arxiv that do exactly what you wanted.

    "torch.manual_seed(3407) is all you need"! draft 📜: davidpicard.github.io/pdf/lucky_seed… Sorry for the title. I promise it's not (entirely) just for trolling. It's my little spare time project of this summer to investigate unaccounted randomness in #ComputerVision and #DeepLearning. 🧵👇 1/n

    Please @OpenAI change your name ASAP. It's an insult to our intelligence to call yourself "open" and release that kind of "technical report" that contains no technical information whatsoever.

    Folks, I'm furious🤬and need to vent. I have this paper that has been in rejection hell for a year and it needs some love🥰 If you're in retail/image search, it could have major impact on your business. I'll explain it👇and then rant on bad reviews. 📜: arxiv.org/abs/2306.02928

    Says a lot about training data leaks. And to think of all the personal information that people are feeding to online chatbots for free...

    Just put online my #MachineLearning course at @EcoledesPonts! It's not very different from the bazillion that already exist, but it's mine! 🥰 Also, it's all python notebooks cause I want to show actual implementations and not just fancy figures. 🤖 davidpicard.github.io/teaching/

    Wow! Looking at other reviews, I'm impressed by the nastiness of my fellow reviewers for #ICCV2021. So many "strong rejects" that are "very confident" and particularly aggressive. Chill out, it's not the end of the world if you don't like that paper!
