KDD 2019 | Policy Learning for Malaria Control

Getting Started in Python


Example starter code*

*Updated 29th April

Please use the following class template as a pattern to encapsulate your submission.

You may modify it extensively, however you must:

  • permit the environment object to be passed in the class initialization, and
  • implement the "generate" method to return the best policy developed by your algorithm. In this template, you are free to add (but not remove) methods, parameters, etc. and also to set defaults for any of your additional parameters which permit your code to perform at its best. Only the generate method will be called during the evaluation process, and no parameters will be passed.

*Updated 1st July

A proving environment is also available for participants to hone their submission before the 6th July Deadline

Previous environments may be replaced with the class:

ChallengeProveEnvironment()

*Updated Submissions:

Note: your XX.zip file should consist of your single code submission titled submission.py which has within it your CustomAgent() class and a Requirements.txt file which may be auto-generated.

Example submission: submission.py

from sys import exit, exc_info, argv
import numpy as np
import pandas as pd

!pip3 install git+https://github.com/slremy/netsapi --user --upgrade

from netsapi.challenge import *

class CustomAgent:
    def __init__(self, environment):
        self.environment = environment

    def generate(self):
        best_policy = None
        best_reward = -float('Inf')
        candidates = []
        try:
            # Agents should make use of 20 episodes in each training run, if making sequential decisions
            for i in range(20):
                self.environment.reset()
                policy = {}
                for j in range(5): #episode length
                    policy[str(j+1)]=[random.random(),random.random()]
                candidates.append(policy)
                
            rewards = self.environment.evaluatePolicy(candidates)
            best_policy = candidates[np.argmax(rewards)]
            best_reward = rewards[np.argmax(rewards)]
        
        except (KeyboardInterrupt, SystemExit):
            print(exc_info())
            
        return best_policy, best_reward

I want to know more about Malaria? 

 

 

What are ITNs and IRS? 

 

Insecticide Treated Nets (ITNs) and Indoor Residual Spraying (IRS) are among the most studied interventions in modelling malaria transmission 

 

Where can I find more information about Reinforcement Learning? 

 

It is a subject covered in terms of our material in the tutorial but you will find extensive reading materials and many useful blogs based on your level and interest. 

 

What malaria setting is being modelled? 

 

For the purposes of this challenge we have developed our own model for an abstract location, to avoid any distraction outside of the KDD cup environment. And preventing any advantage which could be provided from background material.

Policy Learning for Malaria Control

Malaria is thought to have had the greatest disease burden throughout human history, while it continues to pose a significant but disproportionate global health burden. With 50% of the world’s population at risk of malaria infection.  Sub Saharan Africa is most affected, with 90% of all cases.


Through this KDD Cup|Humanity RL track competition we are looking for participants to apply machine learning tools to determine novel solutions which could impact malaria policy in Sub Saharan Africa. Specifically, how should combinations of interventions which control the transmission, prevalence and health outcomes of malaria infection, be distributed in a simulated human population.



This challenge has been framed as a Reinforcement Learning problem, participants are expected to submit high performing solutions to the sequential decision making task. For this competition, actions receive stochastic and delayed rewards, which are resource constrained by both the monetary and computational costs associated with implementing and observing the impact of an action.

 

Submissions are encouraged from participants who may not have previous experience in reinforcement learning problems, reading through the materials we hope you may see the necessity for contributions to inform decision making for this complex real-world problem.
