分享一篇很有趣的 文章。用梯度提升的方法来改进 ARIMA，AutoARIMA 先拿到起始参数，Boosting 过程和普通 GBM 一样都是用残差代替梯度计算。角度倒是听新颖的， 就是听着可能速度有点慢，而且不能确定序列角度来说 Boosting 是否真的有意义，作者在 Kaggle 去年的 M4 上做了些实验，看着还行，有点意思。轮子在这里：https://github.com/tblume1992/ThymeBoost

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.
You guessed it – the internet is your friend. A good place to start looking for Telegram channels is Reddit. This is one of the biggest sites on the internet, with millions of communities, including those from Telegram.Then, you can search one of the many dedicated websites for Telegram channel searching. One of them is telegram-group.com. This website has many categories and a really simple user interface. Another great site is telegram channels.me. It has even more channels than the previous one, and an even better user experience.These are just some of the many available websites. You can look them up online if you’re not satisfied with these two. All of these sites list only public channels. If you want to join a private channel, you’ll have to ask one of its members to invite you.
