Cramér-type Moderate Deviation for Quadratic Forms with a Fast Rate

Xiao Fang, Song-Hao Liu, Qi-Man Shao

Let $X_{1}, \dots, X_{n}$ be independent and identically distributed random vectors in $R^{d}$ . Suppose $E X_{1} = 0$ , $Cov (X_{1}) = I_{d}$ , where $I_{d}$ is the $d\times d…

Estimating the Arc Length of the Optimal ROC Curve and Lower Bounding the Maximal AUC

Song Liu

In this paper, we show the arc length of the optimal ROC curve is an $f$ -divergence. By leveraging this result, we express the arc length using a variational objective and estimate…

Continual Density Ratio Estimation in an Online Setting

Yu Chen, Song Liu, Tom Diethe +1

In online applications with streaming data, awareness of how far the training or test set has shifted away from the original dataset can be crucial to the performance of the model.…
