Which Similarity-Sensitive Entropy (Sentropy)?
Phuc Nguyen, Josiah Couch, Rahul Bansal +5
Shannon entropy is not the only entropy that is relevant to machine-learning datasets, nor possibly even the most important one. Traditional entropies such as Shannon entropy captu…
GEM-T: Generative Tabular Data via Fitting Moments
Miao Li, Phuc Nguyen, Christopher Tam +6
Tabular data dominates data science but poses challenges for generative models, especially when the data is limited or sensitive. We present a novel approach to generating syntheti…
X-Factor: Quality Is a Dataset-Intrinsic Property
Josiah Couch, Miao Li, Rima Arnaout +1
In the universal quest to optimize machine-learning classifiers, three factors -- model architecture, dataset size, and class balance -- have been shown to influence test-time perf…
Grade Inflation in Generative Models
Phuc Nguyen, Miao Li, Alexandra Morgan +2
Generative models hold great potential, but only if one can trust the evaluation of the data they generate. We show that many commonly used quality scores for comparing two-dimensi…
