分享一篇介绍 Data Leak 的文章,说起 data leak 我早期是真的深受其害,毕竟真实世界的线上业务永远有一个特别的维度:时间。理论上完全服从独立同分布业务数据/问题并不多,所以很多时候我们是直接把时间维度忽略掉。若干年前参加过知乎的一次给短文本预测 tag 的竞赛最后也是因为当时原始数据存在一些 data leak(知乎作为举办方提供数据的时候把时间轴抹掉,但是数据本身又其实是时间排序的),最后的排名引起挺大的争议。对于 data leak 系统地考虑是线上数据科学工作非常重要的一环。https://towardsdatascience.com/data-science-mistakes-to-avoid-data-leakage-e447f88aae1c

During the meeting with TSE Minister Edson Fachin, Perekopsky also mentioned the TSE channel on the platform as one of the firm's key success stories. Launched as part of the company's commitments to tackle the spread of fake news in Brazil, the verified channel has attracted more than 184,000 members in less than a month. It’s yet another bloodbath on Satoshi Street. As of press time, Bitcoin (BTC) and the broader cryptocurrency market have corrected another 10 percent amid a massive sell-off. Ethereum (EHT) is down a staggering 15 percent moving close to $1,000, down more than 42 percent on the weekly chart. How to build a private or public channel on Telegram?
