Clustering is a basic process in data analysis. It aims to partition a set of objects into groups called clusters such that, ideally, objects in the same group are similar and objects in different groups are dissimilar to each other. There are many scenarios where such a partition is useful. It may, for example, be used to structure the data to allow efficient information retrieval, to reduce t...

music analysis, information retrieval, multimedia indexing We motivate the problem of music recommendation based solely on acoustics from groups of related songs or 'song sets'. We propose four solutions which can be used with any acoustic-based similarity measure. The first builds a model for each song set and recommends new songs according to their distance from this model. The next three app...

We present a method to reduce a formal context while retaining much its information content. Although simple, our ICRA approach offers an effective way to reduce the complexity of concept lattices and / or knowledge spaces by changing only little information in comparison to a competing model which uses fuzzy K-Means clustering.

Assignment methods are at the heart of many algorithms for unsupervised learning and clus­ tering in particular, the well-known K -mean.! and E:z:pectation-Mazimi$ation (EM) algorithms. In this work, we study several different methods of assignment, including the "hard" assignments used by K-means and the "soft" assignments used by EM. While it is known that K-means minimizes the distortion on ...

In this paper, we explored how to use meta-data information in information retrieval task. We presented a new language model that is able to take advantage of the category information for documents to improve the retrieval accuracy. We compared the new language model with the traditional language model over the TREC4 dataset where the collection information for documents is obtained using the k...
