Density-ratio

Density-ratio estimation

Investigating the density-ratio based clustering and anomaly detection. The latest multi-dimensional distance scaling method **DScale** (PAKDD-18) can be obtained from **[here](https://github.com/zhuye88/Distance-Scaling)**.

A Distance Scaling Method to Improve Density-Based Clustering

We propose a multi-dimensional scaling method, named DScale, which rescales based on the computed distance.

Anomaly detection of aircraft lead-acid battery

We propose a new measure called Local Contrast, as an alternative to density, to find cluster centers and detect clusters.

Density-ratio based clustering for discovering clusters with varying densities

We propose a new measure called Local Contrast, as an alternative to density, to find cluster centers and detect clusters.
