Other relevant neural algorithms include

- the exploratory projection pursuit algorithms, which have also been applied to ICA [47,49]. Due to the close connection between ICA and projection pursuit, it should not be surprising that projection pursuit algorithms can be used directly to solve the ICA problem,
- the least-squares type algorithms in [85], which are based on the non-linear PCA criteria, and
- the algorithm in [106], which is an adaptive algorithm related to higher-order cumulant tensors (see Section 4.3.5).
