TRISEP_ML_tutorial

Introduction

This repository holds the notebooks and code for the Machine Learning tutorial at TRISEP 2019 on August 1st and 2nd. We will explore the application of Convolutional Neural Networks to the problem of particle identification in Water Cherenkov Detector. Before proceeding please fork this repository by clicking on a button above in top right corner of the page.

Acknowledgements

I borrowed code liberally from code and tutorials developed by Kazu Terao and code by Julian Ding and Abhishek Kajal. Big thanks also to the Water Cherenkov Machine Learning collaboration for lending their data - particularly Nick Prouse for actually running the simulations and to Julian for 'massaging' the data. Big Thanks to Amazon Web Services for providing the computing resources enabling us to run this session

Starting on TRIUMF resources

Log into triumf-ml1.triumf.ca Your username has been derrived from your email by taking the part before the @ character and removing dashes and dots. e.g. email winston-niles.rumfoord@infundibulum.space gives username winstonnilesrumfoord. If the private key corresponding to the public key you gave me is not your default key you will need to specify it explicitly.

ssh -Y -i <path/my_private_key> <my_username>@triumf-ml1.triumf.ca

Then launch a screen/tmux session. Next clone your repository, enter a container where software is installed and launch jupyter notebook server. Instructions on how to set up ssh tunnel and bring up the jupyter root screen will be printed on your terminal.

screen
git clone <your forked repo url> TRISEP_ML_tutorial
cd TRISEP_ML_tutorial
. find_this_ip
./start_container.sh
./start_jupyternotebook.sh

Starting up on AWS instance

Log into your instance. username for everybody is ubuntu:

ssh -Y -i <path/my_private_key> ubuntu@<aws_instance_assigned_to_me>

Then launch a screen/tmux session. Next clone your repository, set up pytorch environment and launch jupyter notebook server. Instructions on how to set up ssh tunnel and bring up the jupyter root screen will be printed on your terminal.

screen
git clone <your forked repo url> TRISEP_ML_tutorial
. anaconda3/bin/activate pytorch_p36
cd TRISEP_ML_tutorial
. find_this_ip
./start_jupyternotebook.sh

If the instructions do not appear wait 10 seconds and then type:

python print_instructions.py

Note that if you are using non-default keys you will need to add -i <my_private_key> right after ssh

Notebook order in the tutorial

The sequence of the tutorial is:

  1. Data_Exploration_And_Streaming.ipynb
  2. MLP_CNN.ipynb
  3. Training diagnostics and performance metrics.ipynb The notebook Training monitor.ipynb is meant to display some live diagnostics during network training process and can be run anytime in parallel.
