单纯的 Boruta 判断特征的时候会依照二项分布的接受或者拒绝来判定对前面生成的影子特征进行筛选。所以如果把 Boruta 的第二阶段(特征metric排序以及筛选)单独拿出来,其实是可以用别的方案进行替换的,比如 SHAP(这里的引用来源也是我之前推荐的一本电子书《interpretable-ML》,强烈推荐)。也确实有轮子在做这样的事情,我自己找了一个 Kaggle 上的 Tabular Dataset 试了一下独立工作效果不太明显,不过提供另外一种特征筛选的方法来做 ensemble 应该是有提升的(吧)。轮子在这里:BorutaShap https://github.com/Ekeany/Boruta-Shap

Telegram has exploded as a hub for cybercriminals looking to buy, sell and share stolen data and hacking tools, new research shows, as the messaging app emerges as an alternative to the dark web.An investigation by cyber intelligence group Cyberint, together with the Financial Times, found a ballooning network of hackers sharing data leaks on the popular messaging platform, sometimes in channels with tens of thousands of subscribers, lured by its ease of use and light-touch moderation.

Export WhatsApp stickers to Telegram on Android

From the Files app, scroll down to Internal storage, and tap on WhatsApp. Once you’re there, go to Media and then WhatsApp Stickers. Don’t be surprised if you find a large number of files in that folder—it holds your personal collection of stickers and every one you’ve ever received. Even the bad ones.Tap the three dots in the top right corner of your screen to Select all. If you want to trim the fat and grab only the best of the best, this is the perfect time to do so: choose the ones you want to export by long-pressing one file to activate selection mode, and then tapping on the rest. Once you’re done, hit the Share button (that “less than”-like symbol at the top of your screen). If you have a big collection—more than 500 stickers, for example—it’s possible that nothing will happen when you tap the Share button. Be patient—your phone’s just struggling with a heavy load.On the menu that pops from the bottom of the screen, choose Telegram, and then select the chat named Saved messages. This is a chat only you can see, and it will serve as your sticker bank. Unlike WhatsApp, Telegram doesn’t store your favorite stickers in a quick-access reservoir right beside the typing field, but you’ll be able to snatch them out of your Saved messages chat and forward them to any of your Telegram contacts. This also means you won’t have a quick way to save incoming stickers like you did on WhatsApp, so you’ll have to forward them from one chat to the other.
