ÐThis paper presents a Similarity-Based Agglomerative Clustering (SBAC) algorithm that works well for data with mixed numeric and nominal features. A similarity measure, proposed by Goodall for biological taxonomy [15], that gives greater weight to uncommon feature value matches in similarity computations and makes no assumptions of the underlying distributions of the feature values, is adopted...

With the beginning of the new millenium, the concept of group interactions in communication systems was boosted by the emergence of Web 2.0 technologies. Based on this new area of application, the notion of group decisions and group preferences also evolved, leading to new requirements for corresponding modeling frameworks. Purely numeric approaches are barely able to meet these newly emerging ...

In this paper, we propose an improved numeric character recognition method which can recognize numeric characters well under low-illuminated and shade-illuminated environment. The LN(Local Normalization) preprocessing method is used in order to enhance low-illuminated and shade-illuminated image quality. The reading area is detected using line segment information extracted from the illumination...

Effective search control for numeric planning domains, in which appropriate numeric resource usage is critical to solving the problem, remains an open challenge in domainindependent planning. Most real-world problems rely on metric resources such as energy, money, fuel or materials. Despite the importance of numbers, few heuristics have been proposed to guide search in such domains. Hoffmann’s ...
