Labeling Clusters- Tagging Resources

by Korinna Bade
"... In order to support the navigation in huge doc-ument collections efficiently, tagged hierarchical structures can be used. Often, multiple tags are used to describe resources. For users, it is impor-tant to correctly interpret such tag combinations. In this paper, we propose the usage of tag groups f ..."

, we consider text documents. One pos-sible direction is to hierarchically cluster documents based on their content and further knowledge like personal clus-tering preferences [Bade and Nürnberger, 2008]. This hier-archy can then be used to browse the collection. However, the labeling

Learning Wormholes for Sparsely Labelled Clustering

by Eng-jon Ong, Richard Bowden
"... Distance functions are an important component in many learning applications. However, the correct function is context dependent, therefore it is advantageous to learn a distance function using available training data. Many existing distance functions is the requirement for data to exist in a space o ..."

Automatic Word Sense Discrimination

by Hinrich Schütze - Journal of Computational Linguistics , 1998
"... This paper presents context-group discrimination, a disambiguation algorithm based on clustering. Senses are interpreted as groups (or clusters) of similar contexts of the ambiguous word. Words, contexts, and senses are represented in Word Space, a high-dimensional, real-valued space in which closen ..."

Clustermap: Labeling clusters in large datasets via visualization

by Keke Chen, Ling Liu - Proc. of ACM Conf. on Information and Knowledge Mgt. (CIKM , 2004
"... With the rapid increase of data in many areas, clustering on large datasets has become an important problem in data analysis. Since cluster analysis is a highly iterative process, cluster analysis on large datasets prefers short iteration on a relatively small representative set. Thus, a two-phase f ..."
Abstract - Cited by 7 (1 self) - Add to MetaCart
-phase framework “sampling/summarization – iterative cluster analysis ” is often applied in practice. Since the clustering result only labels the small representative set, there are problems with extending the result to the entire large dataset, which are almost ignored by the traditional clustering research

A Survey on Transfer Learning

by Sinno Jialin Pan, Qiang Yang
"... A major assumption in many machine learning and data mining algorithms is that the training and future data must be in the same feature space and have the same distribution. However, in many real-world applications, this assumption may not hold. For example, we sometimes have a classification task i ..."

by avoiding much expensive data labeling efforts. In recent years, transfer learning has emerged as a new learning framework to address this problem. This survey focuses on categorizing and reviewing the current progress on transfer learning for classification, regression and clustering problems

Correlation Clustering

by Nikhil Bansal, Avrim Blum, Shuchi Chawla - MACHINE LEARNING , 2002
"... We consider the following clustering problem: we have a complete graph on # vertices (items), where each edge ### ## is labeled either # or depending on whether # and # have been deemed to be similar or different. The goal is to produce a partition of the vertices (a clustering) that agrees as mu ..."

Syntax-Augmented Machine Translation using Syntax-Label Clustering

by Hideya Mino, Taro Watanabe, Eiichiro Sumita
"... Recently, syntactic information has helped significantly to improve statistical ma-chine translation. However, the use of syn-tactic information may have a negative im-pact on the speed of translation because of the large number of rules, especially when syntax labels are projected from a parser in ..."

in syntax-augmented machine translation. In this paper, we propose a syntax-label clus-tering method that uses an exchange algo-rithm in which syntax labels are clustered together to reduce the number of rules. The proposed method achieves clustering by directly maximizing the likelihood of synchronous

Distributional Clustering of Words for Text Classification

by L. Douglas Baker, Andrew Kachites Mccallum , 1998
"... This paper describes the application of Distributional Clustering [20] to document classification. This approach clusters words into groups based on the distribution of class labels associated with each word. Thus, unlike some other unsupervised dimensionalityreduction techniques, such as Latent Sem ..."

Effects of Deworming on Malnourished Preschool Children in India: An Open-Labelled, Cluster-Randomized

Background: More than a third of the world’s children are infected with intestinal nematodes. Current control approaches emphasise treatment of school age children, and there is a lack of information on the effects of deworming preschool children. Methodology: We studied the effects on the heights and weights of 3,935 children, initially 1 to 5 years of age, of five rounds of anthelmintic treatment (400 mg albendazole) administered every 6 months over 2 years. The children lived in 50 areas, each defined by precise government boundaries as urban slums, in Lucknow, North India. All children were offered vitamin A every 6 months, and children in 25 randomly assigned slum areas also received 6-monthly albendazole. Treatments were delivered by the State Integrated Child Development Scheme (ICDS), and height and weight were monitored at baseline and every 6 months for 24 months (trial registration number NCT00396500). p Value calculations are based only on the 50 area-specific mean values, as randomization was by area. Findings: The ICDS infrastructure proved able to deliver the interventions. 95 % (3,712/3,912) of those alive at the end of the study had received all five interventions and had been measured during all four follow-up surveys, and 99 % (3,855/3,912) were measured at the last of these surveys. At this final follow up, the albendazole-treated arm exhibited a similar height gain but a 35 (SE 5) % greater weight gain, equivalent to an extra 1 (SE 0.15) kg over 2 years (99 % CI 0.6–1.4 kg, p = 10 211).
