In this paper we address the problem of discretization in the context of learning Bayesian networks (BNs) from data con­ taining both continuous and discrete vari­ ables. We describe a new technique for multivariate discretization, whereby each continuous variable is discretized while tak­ ing into account its interaction with the other variables. The technique is based on the use of a Bayesian...

background and aim: today, bilingualism is a developing phenomenon which half of the world population is bilingual. auditory system is the main route to language learning, so it is expected that bilingualism has an effect on functions of the auditory system. auditory memory is one of the auditory processes which is a cornerstone of linguistic skills and learning process growth, so that, it has ...

bile duct ligation (bdl) is shown to induce cholestasis-related liver function impairments as well as consequent cognitive dysfunctions (i.e. impaired learning and memory formation). this study investigates the effects of cholestasis (14, 21 and 28 days post bile duct ligation) on spatial and non-spatial novelty detection, using a non-associative task. male mice weighing 30-35 g were used. chol...

objectives: the prospective and retrospective memory questionnaire (prmq) developed by smith (2000) and consists of a series of questions about memory weakness that can be encountered anyone in everyday life. the self-reported questionnaire has 16 items that assessing of prospective and retrospective memory problems in everyday life and the aim of the present research was to examine the investi...

An emerging body of literature suggests that the richness of native and naturalized plant species are often positively correlated. It is unclear, however, whether this relationship is robust across spatial scales, and how a disturbance regime may affect it. Here, I examine the relationships of both richness and abundance between native and naturalized species of plants in two mediterranean scru...

background and objective: tamoxifen is one of the selective estrogen receptor modulators that exerts estrogen / anti-estrogen effects in various tissues. this study was done to evaluate the effect of chronic administration of tamoxifen on spatial memory and passive avoidance task in adult male wistar rats. methods: in this experimental study, 48 adult male wistar rats were randomly divided into...

objective: this study aimed to investigate the verbal memory and working memory impairment in healthy siblings of patients with schizophrenia.  methods: the purpose of this study was to compare cognitive deficits in siblings of the patients with schizophrenia and control group. a total of 35 unaffected siblings of patients with schizophrenia were selected from the relatives of the patients refe...
