AAIA'18 Data Mining Challenge: Predicting Win-rates of Hearthstone Decks

AAIA'18 Data Mining Challenge is the fifth competition organized within the framework of International Symposium Advances in Artificial Intelligence and Applications (https://fedcsis.org/2018/aaia). This time, the task is to assess win-rates of Hearthstone decks in games played between AI bots. The competition is kindly sponsored by Silver Bullet Labs, eSensei and Polish Information Processing Society (PTI).

Overview

This year's competition is a continuation of the topic from the previous year - data analytics related to video games. In particular, we focus on a popular collectible card video game Hearthstone: Heroes of Warcraft.

The purpose of this challenge is to discover reliable algorithms for predicting win-rates of Hearthstone decks. The task for participants is to construct a prediction model that can learn win chances of new decks, based on a history of match-ups between AI bots playing with similar decks. In order to give participants a freedom of choosing a representation of the data, apart from a preprocessed dataset in a tabular format, we provide raw JSON files that describe each game in more details - we are interested whether the data regarding the way in which cards are played during the game can be useful in the proposed task.

More details regarding the task and a description of the competition data can be found in Task description section.

Special session at AAIA'18: As in previous years, a special session devoted to the competition will be held at the conference. This year, it is called International Workshop on AI Methods in Data Mining Challenges (DMGATE). We will invite authors of selected reports to extend them for publication in the conference proceedings (after reviews by Organizing Committee members) and presentation at the conference. The publications will be treated as short papers and will be indexed by IEEE Digital Library and Web of Science. The invited teams will be chosen based on their final rank, innovativeness of their approach and quality of the submitted report. We also encourage regular paper submissions to this event, describing new approaches for analyzing data sets published during any of the challenges organized at Knowledge Pit.

Terms & Conditions

Contest Participation Rules:

The competition is open to all interested researchers, specialists, and students. Only members of the Contest Organizing Committee and employees of Silver Bullet Labs cannot participate.
Participants may submit solutions as teams made up of one or more persons.
Each team needs to designate a leader responsible for communication with the Organizers. A single person can be a leader of only one team.
One person may be incorporated into maximally 3 teams.
Each team needs to be composed of a different set of persons.
Each team is obliged to provide a short report describing their final solution. The report must contain information such as the name of the team, names of all team members and a brief overview of the used approach.

Task description

Data description and format: The data for this competition is provided in two different formats. The main one is a collection of JSON files which describe in details games played between four different bots using 400 Hearthstone decks. These games can be used to estimate win-rate of the decks and learn how particular cards are used by the bots. Based on this knowledge, the task for participants is to estimate win-rates of a different set of 200 decks, played by the same bots.

The decks used in the provided collection of training games are given in a separate file named trainingDecks.json. Each row of this file corresponds to a different deck and stores a JSON with a deck identifier, hero identifier, and a list of card names along with their cardinality in the deck (there can be one or two cards of the same type in a deck). Analogically, the descriptions of test decks are provided in the same format in the file testDecks.json. It is allowed to use external knowledge bases about Hearthstone cards as long as they are publically available and their source is clearly stated in the submitted competition report. One example of such a source is the HearthPwn portal.

For the convenience of participants, we provide an additional table training_games.csv, whose rows correspond to JSON files describing the games between bots. Each row of this table gives a simple summary of the corresponding game. In particular, it provides ids of the playing bots, decks which they were using and the result of the game.

The format of submissions: The participants of the competition are asked to predict win-rates of 200 Hearthstone decks described in the file testDecks.json for the four bots which were used to generate the training data. The predictions should be sent using the submission system which will become available on April 13, 23:59 GMT. A file with a solution should consist of 800 lines, formatted in the same way as the exemplary solution provided as the file testSubmissionTemplate.csv. In each line, there should be an identifier of a bot, id of a deck and the predicted win-rate separated by semicolons. The win-rates should be expressed as percentages (real numbers between 0.0 and 100.0).

Evaluation of results: The submitted solutions will be evaluated online and the preliminary results will be published on the competition leaderboard. The preliminary score will be computed on a small subset of the test records, fixed for all participants. The final evaluation will be performed after completion of the competition using the remaining part of the test records. Those results will also be published online. It is important to note that only teams which submit a report describing their approach before the end of the contest will qualify for the final evaluation. The winning teams will be officially announced during a special session devoted to this competition, which will be organized at the FedCSIS'18 conference.

The assessment of solutions will be done using the RMSE measure. In order to keep the rule that the higher the score the better result, scores on the Leaderboard will correspond to minus RMSE values. For every pair bot-test deck, the reference win-rates were computed only based on games with the bots and decks from the training data.
