I think the PyMVPA list is the perfect place to discuss these issues!
Many of the people using PyMVPA are new to machine learning, and may
find it hard to express their problem in terms that machine learning
experts understand and/or to interpret the answers. Also neuroscientists
tend to ask slightly different questions than machine learners or BCI
people - often our primary interest is understanding why we were able to
decode, rather than just improving the raw prediction accuracy. And we
also use some rather peculiar algorithms (e.g. a search for CSP comes up
empty on metaoptimize). So I think we should take advantage of our
particular community to exchange ideas and expertise,
