MixAll: Clustering Mixed data with Missing Values

نویسنده

  • Serge Iovleff
چکیده

The Clustering project is a part of the STK++ library (Iovleff 2012) that can be accessed from R (R Development Core Team 2013) using the MixAll package. It is possible to cluster Gaussian, gamma, categorical, Poisson, kernel mixture models or a combination of these models in case of mixed data. Moreover, if there is missing values in the original data set, these missing values will be imputed during the estimation process. These imputations can be biased estimators or Monte-Carlo estimators of the Maximum A Posteriori (MAP) values depending of the algorithm used.

Dynamic Clustering-Based Estimation of Missing Values in Mixed Type Data

The appropriate choice of a method for imputation of missing data becomes especially important when the fraction of missing values is large and the data are of mixed type. The proposed dynamic clustering imputation (DCI) algorithm relies on similarity information from shared neighbors, where mixed type variables are considered together. When evaluated on a public social science dataset of 46,04...

Dealing with Incomplete Data in Clustering

Over the years, significant developments have taken place in the direction of clustering numeric, categorical or mixed data. A new challenge is to cluster data with missing attribute values. The early algorithms used Fuzzy c-means to partition data into fuzzy clusters and estimate the missing values through estimation algorithms. Recently, Hathaway and Bezdek have proposed four strategies for e...

On a Fuzzy c-means Algorithm for Mixed Incomplete Data Using Partial Distance and Imputation

The focus of fuzzy c-means clustering method is normally used on numerical data. However, most data existing in databases are both categorical and numerical. To date, clustering methods have been developed to analyze only complete data. Although we sometimes encounter data sets that contain one or more missing feature values (incomplete data), traditional clustering methods cannot be used for s...

Clustering Algorithm for Incomplete Data Sets with Mixed Numeric and Categorical Attributes

The traditional k-prototypes algorithm is well versed in clustering data with mixed numeric and categorical attributes, while it is limited to complete data. In order to handle incomplete data set with missing values, an improved k-prototypes algorithm is proposed in this paper, which employs a new dissimilarity measure for incomplete data set with mixed numeric and categorical attributes and a...
