This tool is made for education only and should not be regarded as a finished product of any kind, nor should the price estimations given by the program trusted blindly.

Introduction

This tools is an attempt to leverage the kNN classification approach to price poe items, including rare or unique objects.

The project contains two main programs :

• An indexer to pull data from the API and store them into a local MongoDB installation, indexer.js
• A kNN classifier to compare item features and attempt to deduce price, main.js

Installation

To get this tool running you will need to:

• Install NodeJS from https://nodejs.org/en/ or your repo management tool
• Install MongoDB
• Finally, you'll need to open a terminal if not already done, change directory to the project folder and install the project dependencies by doing npm install

Running

To run the indexer, type node ./indexer.js. To run the classifier, type node ./main.js.

To specify the league, the properties of the object or the amount of neighbors to use, you can tweak the code of the classifier.
