Which is the Best Yatsuhashi Brand for a Souvenir?

Experiments for the technical paper Which is the Best Yatsuhashi Brand for a Souvenir? (私たちはお土産にどの八ッ橋を買えばよいのか).

Dependencies

Python 3.5
numpy 1.11.1
scipy 0.17.1

Usage

Clone this repository:

$ git clone https://github.com/r-takahama/YATSUHASHI.git

Move working directory:

$ cd YATSUHASHI/src

Run python code for checking the result of experiments:

$ python calcScore.py

And you will obtain the following output:
