In this paper, we study the use of support vector machine in text categorization. Unlike other machine learning techniques , it allows easy incorporation of new documents into an existing trained system. Moreover, dimension reduction, which is usually imperative, now becomes optional. Thus, SVM adapts eeciently in dynamic environments that require frequent additions to the document collection. ...

Mobility is the core property of mobile network. But such network can have fixed or mobile communicating nodes. A special categorization of mobile network in which communicating nodes are moving in high speed is called speed network. In such network, algorithmic approach and the network throughput depends on node speed and dynamic architecture. In this paper, a detail study on speed network is ...

PSL*. We would like to thank Neil Stewart for supplying the 42 stimulus presentation orders and the children and staff who assisted with the study. Sequence Effects in Autism 2 Categorization decisions that reflect constantly changing memory representations may be an important adaptive response to dynamic environments. We assessed one such influence from memory, sequence effects, on categorizat...

Categorization axioms have been proposed to axiomatizing clustering results, which offers a hint of bridging the difference between human recognition system and machine learning through an intuitive observation: an object should be assigned to its most similar category. However, categorization axioms cannot be generalized into a general machine learning system as categorization axioms become tr...

We compared learning by amnesic and control participants in the “Weather Prediction” task, a widely-used probabilistic categorization task. Earlier studies with the WP task (e.g., Knowlton et al., 1994) found no difference in early categorization performance between amnesic and control participants. This has been taken as evidence for a multiple memory systems view, in which categorization lear...

Dividing the acoustic repertoires of animals into biologically relevant categories presents a widespread problem in the study of animal sound communication, essential to any comparison of repertoires between contexts, individuals, populations, or species. Automated procedures allow rapid, repeatable, and objective categorization, but often perform poorly at detecting biologically meaningful sou...

Different patterns of performance across vowels and consonants in tests of categorization and discrimination indicate that vowels tend to be perceived more continuously, or less categorically, than consonants. The present experiments examined whether analogous differences in perception would arise in nonspeech sounds that share critical transient acoustic cues of consonants and steady-state spe...
