📝 Summary (1/2): Cost-sensitive classification is critical in applications where misclassification errors widely vary in cost. However, overparameterization poses fundamental challenges to the cost-sensitive modeling of deep neural networks (DNNs). To address this challenge, ...

(2/2) this paper proposes a cost-sensitive adversarial data augmentation framework to make overparameterized models cost-sensitive. The overarching idea is to generate targeted adversarial examples that push the decision boundary in cost-aware directions.

📷 Summary: This work leverages a computational conjecturing framework to produce nonlinear bounds for continuous features and boolean expressions for categorical features based on input data. Their method recovers known patterns in data that no previous method could find.

(2/3) The authors introduce three tree-based density estimation methods for binary/categorical data. Its models are sparse, and users can specify the desired number of leaves, branches, or rules with a prior.

(3/3) This introduces high-dimensional analogs to the histogram. The Bayesian priors encourage sparsity, allowing for interpretability and the models are 50 times sparser than high-dimensional histograms on crime data that describe how often different types of break-ins occur.

(2/3) "This work introduces a modeling approach, inspired by backward elimination and incorporating a cost hierarchy to minimize information loss. The cost of each condition is modeled as a function of the number of other, more expensive chronic conditions an individual has."

(3/3) "The hierarchical model adeptly captures intricate interactions, offering potential enhancements in decision-making, particularly in situations where enumerating all possible factor combinations is impractical, such as in financial risk scoring and pay structure design."
