Principal feature analysis: a multivariate feature selection

WebMultivariate statistical analysis often begins by identifying a set of features that capture the informa-tive aspects of the data. For example, in fMRI analysis one might select a subset of voxels within an anatomical region of interest (ROI), or select a subset of principal components of the ROI, then use these features for subsequent analysis. WebMultivariate and model-free fMRI methods represent promising techniques to overcome these limitations by investigating the functional role of distributed patterns of neural activity without assuming a specific model. Multivariate model-free methods are based on machine learning and pattern recognition algorithms. Web8 aug. 2012 · National Center for Biotechnology Information jeansrock wrangler
