Great!
I will implement exporting patterns first. And then the interestingness
evaluation inside 1-gram pattern when Nil gives the small test corpus.
BTW, there's gonna be a bit of time before I can hand you the corpus as
I'm attempting to generate it from an actual inference control learning
experiment, I'd say in a week or so.
Meanwhile if you could take a look at
https://github.com/opencog/opencog/issues/2787
specifically the first item which is a question to you. Also, having the
pattern miner unit test pass would be great. As I explain at the end of
the issue, I may prefer to do these changes myself as they will help me
to get familiar with the pattern miner code. Of course if you'd rather
take care of them, for educational purpose or whatnot, you are free to
do so as well.
Nil
Thanks,

Well it seems that the mathematical basis of the interestingness
evaluation is the same whether we view this as a 3-gram pattern or as
a 1-gram pattern
So I guess the answer is that, yeah, the interestingness evaluation
has to be able to look at multiple variables within a "1-gram" and
also across different "grams" ...
There may be surprisingness
-- within a single "gram"
-- among multiple "grams"
-- involving, say, 2 variables in one gram, and then 2 variables in
another gram
(where i'm using "gram" as a shorthand for "set of Atoms supervened
over by a single root link")
