procrustes_alignment¶
Synopsis¶
Performs gradient alignment through iterative singular value decomposition (source code).
Usage¶
aligned = procrustes_alignment(gradients,varargin)
- gradients: cell array of gradients
- varargin: Name-value pairs (see below).
- aligned: Aligned gradients.
Description¶
Gradient alignment through Procrustes analysis [see (Langs et al., 2015)]. On the first iteration all gradients are aligned to either the first provided gradient set or to a template (see Name-Value pairs) using singular value decomposition. On every subsequent iteration alignment is to the mean.
Name-Value pairs¶
- nIterations: Number of iterations to run (default: 100).
- reference: Template to align to on the first iteration (default: first provided gradient set)
