PRML

In this repository, various machine learning algorithms in 「Pattern Recognition and Machine Learning」are implemented without using machine learning packages such as scikit-learn.

All the algorithms are implemeted in the directory prml. In short_notebook directory, I use prml package (which I make myself). This notebooks are short-version, so this is useful when you want to see how these algorithms work.

However, many people must want to know how these algorithms are implemented. These notebooks in notebook directory meet this need. In notebook, nothing of prml is used. All algorithms are implemented in almost the same way as prml. You can write and modify the code in jupyter notebook.

Setup

There are three suggested ways to set up the environment to run this python repository. There are many other ways to set up, but Example2 may be the best way (because it doesn't take so much time to build docker image)

Example1
You can clone this repository and make virtual environment.

# clone repository and make venv 

git clone https://github.com/hedwig100/PRML && cd PRML
chmod 755 setup.sh && ./setup.sh
python3 -m venv prml_venv 

source prml_venv/bin/activate
pip install -r requirements.txt # in virtual environment 
pip install notebook

Example2
You can clone this repository and build docker image. You need to have docker installed.

# clone repository and build docker image
git clone https://github.com/hedwig100/PRML && cd PRML
docker build -t prml .
docker run -it --name prml -p 8888:8888 prml /bin/bash

# in docker container 
cd PRML && ./setup.sh

in docker container, you can use jupyter notebook command.

Example3
You can pull docker image from docker hub. This image is uploaded to docker hub.
In this way, you cannot see document because no document is in the docker container.

# pull docker image and run
docker pull hedwig100/prml:latest
docker run -it --name prml -p 8888:8888 hedwig100/prml:latest /bin/bash

# in docker container 
cd PRML && ./setup.sh

in docker container, you can use jupyter notebook command.
