Stepwise: Stepwise Classification of Cancer Samples using Clinical and Molecular Data

Stepwise classification of cancer samples using clinical and molecular data Additional file

where ρ is the correlation between x1 and x2. For each random number we sample ρ from the uniform distribution (0, 0.5). We set this correlation range because we want to illustrate the performance of the indirect mapping in a setting of low correlation between the two data types. In order to represent noisy data types we added independent standard Gaussian noise to both x1 and x2. We treat x1 a...

stepwiseCM: Stepwise Classification of Cancer Samples using High-dimensional Data Sets

This vignette shows the use of the stepwiseCM package for the integrative analysis of two heterogeneous data sets. For more detailed information on the algorithm and assumptions we refer to the article (Obulkasim et al, 2011) and its supplementary material. Throughout this vignette we use low dimensional clinical covariates and high-dimensional molecular data (gene expression) to illustrate the...

stepwiseCM: An R Package for Stepwise Classification of Cancer Samples Using Multiple Heterogeneous Data Sets

This paper presents the R/Bioconductor package stepwiseCM, which classifies cancer samples using two heterogeneous data sets in an efficient way. The algorithm is able to capture the distinct classification power of two given data types without actually combining them. This package suits for classification problems where two different types of data sets on the same samples are available. One of...

the clustering and classification data mining techniques in insurance fraud detection:the case of iranian car insurance

با توجه به گسترش روز افزون تقلب در حوزه بیمه به خصوص در بخش بیمه اتومبیل و تبعات منفی آن برای شرکت های بیمه، به کارگیری روش های مناسب و کارآمد به منظور شناسایی و کشف تقلب در این حوزه امری ضروری است. درک الگوی موجود در داده های مربوط به مطالبات گزارش شده گذشته می تواند در کشف واقعی یا غیرواقعی بودن ادعای خسارت، مفید باشد. یکی از متداول ترین و پرکاربردترین راه های کشف الگوی داده ها استفاده از ر...
