之前推过一篇 Facebook 的 ConvNeXT，今天又看到一个上个星期新出来的 XFormer，直接把二次的 attention 换成了线性 attention，也是在 ViTs 的基础上想办法减少资源使用。没看到什么别的新奇的地方。主要就是减少 GPU 使用，对数据量要求也低了不少，我没做实验。https://arxiv.org/abs/2201.10271，作者给了代码：https://github.com/pranavphoenix/cxv

Telegram is riding high, adding tens of million of users this year. Now the bill is coming due.Telegram is one of the few significant social-media challengers to Facebook Inc., FB -1.90% on a trajectory toward one billion users active each month by the end of 2022, up from roughly 550 million today.
In recent times, Telegram has gained a lot of popularity because of the controversy over WhatsApp’s new privacy policy. In January 2021, Telegram was the most downloaded app worldwide and crossed 500 million monthly active users. And with so many active users on the app, people might get messages in bulk from a group or a channel that can be a little irritating. So to get rid of the same, you can mute groups, chats, and channels on Telegram just like WhatsApp. You can mute notifications for one hour, eight hours, or two days, or you can disable notifications forever.
