Reading the documentation, it seems that scikit's RBM does not support
continuous values or, more precisely, values that are larger than one or
less than zero; since logistic is the output function.
This paper, "http://www.ee.nthu.edu.tw/~hchen/pubs/iee2003.pdf
<http://www.ee.nthu.edu.tw/%7Ehchen/pubs/iee2003.pdf>", however,
explains how you can code RBM that supports continuous values - adding
zero-mean gaussian noise to the sampled value. It doesn't seem difficult.
Did someone open a pull-request that adds this functionality?
If no, then I can to work on it ;)
Thanks
