WebJan 1, 2003 · Our results suggest that a significant proportion of the variance in fMRI data is in fact deterministic. Double ICA training with different initial weight matrices is a simple and practical method to determine which components are reproducible. WebClustering functional magnetic resonance imaging (fMRI) time series has emerged in recent years as a possible alternative to parametric modeling approaches. Most of the work so far has been concerned with clustering raw time series.

WebMost methods used for fMRI analysis assume that observations are independent and that the noise can be treated as white gaussian noise. These assumptions are usually not true but it is difficult to assess how severely these assumptions are violated and what are their practical consequences.
