一个新的分子式推算生成工具，FastFlows。从名字也可以看出来基本上就是用了 NF，从功能的角度来说和 VAE，GAN 什么的区别并不大，不过NF 的目标换成了去寻找一个和数据集后验分布一样的分布，也可以计算似然，用双射映射的一系列操作把原始分布弄成新的分布，经典案例就是对高斯分布作各种花里胡哨的转换。我个人对 NF 没有太多特别的感觉，这个框架感觉也只是用了 NF 做一个实验，没看出来有什么量化效果比 VAE 或者 GAN更好。
不过这个 repo 挺牛逼的，都是化学，生物，和材料领域一些深度学习的应用，tutorial 挺全的。 https://github.com/deepchem/deepchem/

Telegram’s stand out feature is its encryption scheme that keeps messages and media secure in transit. The scheme is known as MTProto and is based on 256-bit AES encryption, RSA encryption, and Diffie-Hellman key exchange. The result of this complicated and technical-sounding jargon? A messaging service that claims to keep your data safe.Why do we say claims? When dealing with security, you always want to leave room for scrutiny, and a few cryptography experts have criticized the system. Overall, any level of encryption is better than none, but a level of discretion should always be observed with any online connected system, even Telegram.
Like a stock, you can buy and hold Bitcoin as an investment. You can even now do so in special retirement accounts called Bitcoin IRAs. No matter where you choose to hold your Bitcoin, people’s philosophies on how to invest it vary: Some buy and hold long term, some buy and aim to sell after a price rally, and others bet on its price decreasing. Bitcoin’s price over time has experienced big price swings, going as low as $5,165 and as high as $28,990 in 2020 alone. “I think in some places, people might be using Bitcoin to pay for things, but the truth is that it’s an asset that looks like it’s going to be increasing in value relatively quickly for some time,” Marquez says. “So why would you sell something that’s going to be worth so much more next year than it is today? The majority of people that hold it are long-term investors.”
