In this contribution we investigate a simple pattern formation process [9,10] based on Hebbian learning and competitive interactions within cortex. This process generates spatial representations of afferent (sensory) information which strongly resemble patterns of response properties of neurons commonly called brain maps. For one of the most thoroughly studied phenomena in cortical development,...

The aim of the present study was to determine the extent to which aesthetic preference, previously attributed to cerebral dominance, may be determined by reading habits. One hundred and sixty two normal subjects were presented pairs of images, one being the mirror-image of the other, and were asked for their aesthetic preference. Half of the subjects were left-to-right readers (French subjects)...

The conversational agent understands and provides users with proper information based on natural language. Conventional agents based on pattern matching have many restrictions to manage various types of real dialogues and to improve the answering performance. For the effective construction of conversational agents, we propose a domain-adaptive conversational agent that infers the user’s intenti...

Conversational case-based reasoning (CBR) systems, which incrementally extract a query description through a user-directed conversation , are advertised for their ease of use. However, designing large case libraries that have good performance (i.e., precision and querying ee-ciency) is diicult. CBR vendors provide guidelines for designing these libraries manually, but the guidelines are diicult...

This paper introduces a Vietnamese text-based conversational agent architecture on specific knowledge domain which is integrated in a question answering system. When the question answering system fails to provide answers to users’ input, our conversational agent can step in to interact with users to provide answers to users. Experimental results are promising where our Vietnamese text-based con...

In this paper we present a framework for conversational awareness and conflict resolution in spoken dialogue systems for home care assistance. Conversational awareness is supported through OWL ontologies for capturing conversational modalities, while interpretation and incremental context enrichment is facilitated through Description Logics reasoning. Conflict resolution further assists the int...

In Voice over IP, the quality of interactive conversation is important to users. Major factors affecting perceived quality are delay, delay jitter, and missing packets. For conversational VoIP, a conversational delay also plays an important role for perceived quality. Large conversational delay can result in double talk, echo or even the termination of the conversation. In practice, a playout b...
