Probabilistic self-organizing maps for qualitative data
We present a self-organizing map model to study qualitative data (also called categorical data). It is based on a probabilistic framework which does not assume any prespecified distribution of the input data. Stochastic approximation theory is used to develop a learning rule that builds an approximation of a discrete distribution on each unit. This way, the internal structure of the input datas...
متن کاملInterpreting Self - Organizing Maps through Space – Time Data Models
Self-organizing maps (SOMs) are a technique that has been used with high-dimensional data vectors to develop an archetypal set of states (nodes) that span, in some sense, the high-dimensional space. Noteworthy applications include weather states as described by weather variables over a region and speech patterns as characterized by frequencies in time. The SOM approach is essentially a neural n...
متن کاملInterpreting and reporting qualitative research.
The aims of this paper were to clarify the nature and purpose of qualitative research and to suggest specific guidelines for reporting the results of qualitative studies. Confusion about the purpose of qualitative research and the absence of a standardized format for reporting such research make it difficult to assess the validity of qualitative studies. Four general purposes of qualitative res...
متن کاملNonparametric Regression Estimation under Kernel Polynomial Model for Unstructured Data
The nonparametric estimation(NE) of kernel polynomial regression (KPR) model is a powerful tool to visually depict the effect of covariates on response variable, when there exist unstructured and heterogeneous data. In this paper we introduce KPR model that is the mixture of nonparametric regression models with bootstrap algorithm, which is considered in a heterogeneous and unstructured framewo...
متن کاملWarehousing Structured and Unstructured Data for Data
More data, especially unstructured data, is available to users than ever. There is so much data available that it is diicult for users to make use of their data in its raw form. To handle the diversity of data types, we have designed and prototyped a multidatabase/warehouse system. The system has been especially designed to facilitate the interaction of structured and unstructured data. The sys...
