Density-ratio

Density-ratio estimation

Investigating the density-ratio based clustering and anomaly detection. The latest data transformation method **CDF-TS** (PRJ-21) can be obtained from **[here](https://github.com/zhuye88/CDF-TS)**.

CDF Transform-and-Shift: An effective way to deal with datasets of inhomogeneous cluster densities

CDF-TS is a preprocessing method to transform data and equalises the density of all clusters.

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.
