Reproducibility Variable Result LLM Response
Research Type Experimental We test our models against four competing algorithms in the literature on two datasets and show that our results improve past performance. We show 2.4% to 16.7% improvement in AUC compared to baselines on one dataset, and a gain of 0.6% to 8.8% in accuracy on the other. Ablation testing shows that Dominance Rank features play a key role.

Pseudocode Yes GDP s pseudo-code is shown as Algorithm 1 and also on Figure 2.
Open Source Code No The paper does not provide an explicit statement or a link to open-source code for the described methodology.
Open Datasets Yes In addition to the Resistance dataset, we used the ELEA dataset developed by [Sanchez-Cortes et al., 2012].
Dataset Splits Yes We split the Resistance dataset into 10 folds by games. As each player appears in only one game, we always make predictions about the dominance of players in games that we have not seen before.
Hardware Specification No The paper does not provide specific hardware details (e.g., CPU/GPU models, memory, or cloud instance types) used for running experiments.
Software Dependencies No The paper mentions tools like 'Amazon s Rekognition' and 'Open Face' but does not provide specific version numbers for any software dependencies.
Experiment Setup Yes Our classifier suite for binary prediction tasks consists of the 5 classifiers: k-Nearest Neighbors, Logistic Regression, Gaussian Naive Bayes, Linear SVM, and Random Forest. We used two classifiers: Multilayer Perceptron (MLP) with two layers, and Random Forest (RF) with 50 estimators.
