This is a collection of my investment assignments. I implemented some classic papers during the course of investment studies
I am assigned to a data collection task, to collect 2000 company information from [owler](www.owler.com) and [crunchbase](www.crunchbase.com) Collecting structured data by hand and feed them into an excel table is always boring and time consuming. So I tried to use web crawl method to solve it and save some time (50 hours work estimated).
In this work, I use R, Bash and Python to extract different countries different indicators in different years. The data have some property: big, not unified(.RData or .csv), some have mistakes. It is very sparse so it waste many storage. And the conversion of Rdata to csv leads some mistakes, so it needs very careful examination and check work. At first I want to store all of them in HDF5 for better IO, but people in my girl friend's working team are't familiar with codes, so I store them in csv. I also think about later work(for example, basic statistical work, model the interaction and time series, maybe a hierarchical time series machine learning model), but I am too busy to help my little bragger to do all kinds of things.

In this paper, we construct two evaluation systems: Renewable Energy Indicator (REI) and Network Instability Indicator (NII). By using data mining methods and developing two models, we succeed in visualizing, characterizing, evaluating and predicting the energy flow network and the use of renewable energy.
