چکیده
Introduction & BackgroundSummarising high-dimensional time series data across multiple entities is an increasingly prevalent problem because mass collection has become routine in most domains. We propose a method of automatically summarising data.
 Objectives ApproachSummarization such context both with regard to reduction the observations and large number temporal points. While numerous methods segment and/or summarise exist, properties often do not align needs consumers summaries or require unrealistic setting parameters. Addressing this, we define set broad that lead high utility class domains, which are determined by information theoretic notion optimality. Intuitively these reflect summarization into lifestates where (1) possible limited shared allow interpretation comparison (2) lifestate-transitions jointly controlled provide parameterless, optimal sample dimensionality.
 Relevance Digital FootprintsExample include: regular survey collection, consumer purchasing history from transactional (where items choose high), other repeatedly sampled digital data. Within Footprints domain, concise descriptions (summarizations) extremely important. For example, within health records could be identified used find critical patterns decline recovery patients.
 Conclusions ImplicationsThis work aims segmentations optimally trade off states segments humans must then interpret, while still capturing salient state changes. Building on prior work, model complexity normalised maximum likelihood (NML). In short, proposed generates automated summarizations informationally rich, according theory, branch mathematics.

Hierarchical Language Identification based on Automatic Language Clustering
Due to the limitation of single-level classification, existing fusion techniques experience difficulty in improving the performance of language identification when the number of languages and features are further increased. Given that the similarity of feature distribution between different languages may vary, we propose a novel hierarchical language identification framework with multi-level cl...
متن کاملFuzzy Clustering Approach Using Data Fusion Theory and its Application To Automatic Isolated Word Recognition
In this paper, utilization of clustering algorithms for data fusion in decision level is proposed. The results of automatic isolated word recognition, which are derived from speech spectrograph and Linear Predictive Coding (LPC) analysis, are combined with each other by using fuzzy clustering algorithms, especially fuzzy k-means and fuzzy vector quantization. Experimental results show that the...

In the first problem, we study the role of visual attributes using an agglomerative clustering algorithm to whittle down the search area where the number of classes is high to improve the performance of clust...
متن کاملAutomatic Speaker Clustering
This paper presents a fully automatic speaker clustering algorithm, which consists of three components: building a distance matrix based on Gaussian models of the acoustic segments; performing hierarchical clustering on the distance matrix with the prior assumption that consecutive segments should be more likely to come from the same speaker; and selecting the best clustering solution automatic...
