Unsupervised Image Clustering Using the Information Bottleneck Method
نویسندگان
چکیده
A new method for unsupervised image category clustering is presented, based on a continuous version of a recently introduced information theoretic principle, the information bottleneck (IB). The clustering method is based on hierarchical grouping: Utilizing a Gaussian mixture model, each image in a given archive is first represented as a set of coherent regions in a selected feature space. Images are next grouped such that the mutual information between the clusters and the image content is maximally preserved. The appropriate number of clusters can be determined directly from the IB principle. Experimental results demonstrate the performance of the proposed clustering method on a real image database.

Applying the Information Bottleneck Principle to Unsupervised Clustering of Discrete and Continuous Image Representations
In this paper we present a method for unsupervised clustering of image databases. The method is based on a recently introduced information-theoretic principle, the information bottleneck (IB) principle. Image archives are clustered such that the mutual information between the clusters and the image content is maximally preserved. The IB principle is applied to both discrete and continuous image...

متن کاملUnsupervised Human Action Categorization with Consensus Information Bottleneck Method
Recent researches have shown consensus clustering can enhance the accuracy of human action categorization models by combining multiple clusterings, which can be obtained from various types of local descriptors, such as HOG, HOF and MBH. However, consensus clustering yields final clustering without access to the underlying feature representations of the human action data, which always makes the ...
متن کاملClustering using the Information Bottleneck Method with Annealing
The purpose of this project is to examine the performance of an existing clustering method, Information Bottleneck with Annealing (IBANN), when applied to the task of document clustering. The information bottleneck method (IB) [9] is known as one of the best methods for clustering multi-dimensional data [5] and this variation of IB uses annealing in order to eliminate a preprocessing step norma...
