Using arxiv API to analysis neural network paper in astro-ph
- Simple N-grams analysis on abstract
- Try to find the common topics in astro that used neural network.
- Basic scraping function is adapted from TIMHEAD, http://betatim.github.io/posts/analysing-the-arxiv/, with some modifications.
- Number of total astro-ph papers from arxiv API 2010 - 2018: 234975
- The ratio of neural net or machine learning papers in astro-ph: 0.00258
- How many of them are about galaxy: 0.224
- 1 grams
- 2 grams
- 3 grams: This one is surprising. Number of CNN count is comparable to the number count of neural network. It may imply most of neural network application in astronomy is using CNN.

- Count of monthly arxiv submission
- Count of monthly astro-ph submission
- Comparison : they fit!
- Oct is the most productive month, I wonder why ...
- Astro-ph days in a month :
- not every months have 31s, so it's reasonable.
- Astro-ph days in a week :
- Seems to be quite uniform for me. Except not so many submissions in the weekends. Probably due to some arxiv's submission rules.
