New theory refines function-counting for low-dimensional data structures
Researchers have developed a new mathematical framework to analyze classification capabilities in low-dimensional data. This work extends Cover's (1965) function-counting theory by refining the general position assumpti…

New method calibrates vine copula models using noise contrastive estimation
Researchers have developed a new method to calibrate simplified vine copula models using noise contrastive estimation (NCE). This approach reframes density estimation as a binary classification task, allowing for observ…

New method achieves optimal rate for second-order calibration error
Researchers have characterized the minimax rate for estimating second-order calibration error in binary classification, a measure of how well a predictor's uncertainty matches label probability variance. They found that…
