ArborEnum: Decision Tree Rashomon Sets over Continuous Features
Zakk Heile, Hayden McTavish, Margo Seltzer +1
The Rashomon effect describes the phenomenon that many models can achieve nearly equivalent performance on the same learning task, with significant ramifications for robustness, fe…
Multistage Defer Trees for Hybrid Interpretability: If at First You Can't Succeed, Tree Again
Zakk Heile, Hayden McTavish, Margo Seltzer +1
Recent work has shown that well-optimized individual decision trees can match complex black box models in some settings, primarily in noisy domains. For the remaining settings, how…
CLARITree: Cholesky and Lookahead Accelerations for Regression with Interpretable Piecewise Linear Trees
Yixiao Wang, Hayden McTavish, Varun Babbar +2
Regression trees are among the most interpretable yet expressive model classes in machine learning. Historically, greedy induction has been the dominant approach for constructing w…
From Rashomon Theory to PRAXIS: Efficient Decision Tree Rashomon Sets
Zakk Heile, Hayden McTavish, Varun Babbar +2
Standard machine learning pipelines often admit many near-optimal models. These "Rashomon sets" pose a range of challenges and opportunities for uncertainty-aware, robust decision…
HyperBrain: Anomaly Detection for Temporal Hypergraph Brain Networks
Sadaf Sadeghian, Xiaoxiao Li, Margo Seltzer
Identifying unusual brain activity is a crucial task in neuroscience research, as it aids in the early detection of brain disorders. It is common to represent brain networks as gra…
