Using RDataTracker
Published in pre-print, 2014
RDataTracker is a library of R functions that collects data provenance in the form of a Data Derivation Graph (DDG) when executing an R script or working in the R console.

Predicting Yelp Star Reviews Based on Network Structure with Deep Learning
Published in arxiv, 2017
In this paper, we tackle the real-world problem of predicting Yelp star-review rating based on business features (such as images, descriptions), user features (average previous ratings), and, of particular interest, network properties (which businesses has a user rated before).

Automatic Code Generation using Pre-Trained Language Models
Published in arxiv, 2021
In this paper, we propose an end-to-end machine learning model for code generation in the Python language built on-top of pretrained language models.

Mastering Terra Mystica: Applying Self-Play to Multi-agent Cooperative Board Games
Published in arxiv, 2021
In this paper, we explore and compare multiple algorithms for solving the complex strategy game of Terra Mystica, hereafter abbreviated as TM. Previous work in the area of super-human game-play using AI has proven effective, with recent break-through for generic algorithms in games such as Go, Chess, and Shogi.
