Efficient similarity search for uncertain data is a challenging task in many modern data mining applications like image retrieval, speaker recognition and stock market analysis. A common way to model the uncertainty of data objects is using probability density functions in the form of Gaussian Mixture Models (GMMs), which have an ability to approximate arbitrary distribution. However, due to the possible...
Efficient similarity search in uncertain data is a central problem in many modern applications such as biometric identification, stock market analysis, sensor networks, medical imaging, etc. In such applications, the feature vector of an object is not exactly known but is rather defined by a probability density function like a Gaussian Mixture Model (GMM). Previous work is limited to axis-parallel...
