Classifying sequential data as early and as accurately as possible is a challenging yet critical problem, especially when a sampling cost is high.
We show that the kernel least-squares method has a smaller condition number than a version of kernel mean matching and other M-estimators, implying that the kernel least-squares method has preferable numerical properties.
The objective of change-point detection is to discover abrupt property changes lying behind time-series data.
Subsampling Generative Adversarial Networks: Density Ratio Estimation in Feature Space with Softplus Loss
Our subsampling methods do not rely on the optimality of the discriminator and are suitable for all types of GANs.
Generalization of Change-Point Detection in Time Series Data Based on Direct Density Ratio Estimation
The goal of the change-point detection is to discover changes of time series distribution.
Density ratio estimation (DRE) is at the core of various machine learning tasks such as anomaly detection and domain adaptation.
