Alexander Fabisch 53e015c961 Simplify optimization
* remove L-BFGS, gradient descent finds better visualizations (although the cost is often higher)
* learning_rate is a parameter
* learning schedule:
    * initialize embedding with standard deviation 1
    * 100 episodes with early exaggeration
    * 20 iterations with momentum 0.5
    * then switch to momentum 0.8
    * default learning rate is 100, reasonable range is 100-500

Rajat Khanduja 5e20b8c664 Fixed pep8 violations. Some 'line too long' errors still remain. 2014-05-15 09:23:16 +05:30
Rajat Khanduja 2244098532 Updated examples to use pyplot for plotting instead of pylab
Some examples not updated because scripts throw error (probably not
because of the change)

Robert Layton dacfd8bd5d DOC: Replaced all BSD style licenses with "BSD 3 clause"
Replaced all BSD style licenses with "BSD 3 clause"
Not checked yet!

Removed duplicate "3 clause, 3 clause"

Removed trailing period if exists

Fixed some missed licences, still about 50 to do, but those can be automated

Think I got the last of them.

Apparently me and sed have different ideas of regex.

Found a few more
