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 has made it easier for its users to communicate, as it has introduced a feature that allows more than 200,000 users in a group chat. However, if the users in a group chat move past 200,000, it changes into "Broadcast Group", but the feature comes with a restriction. Groups with close to 200k members can be converted to a Broadcast Group that allows unlimited members. Only admins can post in Broadcast Groups, but everyone can read along and participate in group Voice Chats," Telegram added.
Tata Power whose core business is to generate, transmit and distribute electricity has made no money to investors in the last one decade. That is a big blunder considering it is one of the largest power generation companies in the country. One of the reasons is the company's huge debt levels which stood at ₹43,559 crore at the end of March 2021 compared to the company’s market capitalisation of ₹44,447 crore.
