The cited paper I ("Independent component analysis: Algorithms and applications") includes the following formula:
This formula seems to me to be in error ( is a column vector; the dimensions don't work out). The current version of the article has this formula:
I believe this is also in error (the first term is transposed relative to the second term). I believe the correct version, as implemented in [ scikit-learn's implementation of FastICA] is as follows:
Does this seem right? Can I cite the source code as a reference to update the formula? rdl381 ( talk) 15:59, 19 January 2024 (UTC)
