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/

However, analysts are positive on the stock now. “We have seen a huge downside movement in the stock due to the central electricity regulatory commission’s (CERC) order that seems to be negative from 2014-15 onwards but we cannot take a linear negative view on the stock and further downside movement on the stock is unlikely. Currently stock is underpriced. Investors can bet on it for a longer horizon," said Vivek Gupta, director research at CapitalVia Global Research.
