Hi, thanks,
I just implemented quoting the output patterns and the return AtomSpace:
1. There is a "if_quote_output_pattern" in config file, if it is set to
true, the patterns will be quoted.
2. The quote link type can be define with
"output_pattern_quoted_linktype" in the config file, the default is
MinedPatternLink.
3. The Frequency, InteractionInformation, Surpringness I and II value
are stored in the keyvalue pair of "PatternValues" of the
MinedPatternLink. Can be query by:
MinedPatternLink->getValue(PatternValuesHandle).
4. Also after mining is finished, the AtomSpace contains all the
patterns can be get by the interface: getResultAtomSpace(). By
AtomSpace interface: get_handles_by_type (MINED_PATTERN_LINK ....).
That looks good, I think we can stick with this API for the time being.
For example:
(MinedPatternLink
(EvaluationLink
(PredicateNode "background")
(ListLink
(VariableNode "$var_1")
(ConceptNode "solo_singer")
)
)
(EvaluationLink
(PredicateNode "occupation")
(ListLink
(VariableNode "$var_1")
(ConceptNode "Singer-songwriter")
)
)
)
I had a quick look at the Pattern Miner clean up issue. I will try to
fix some of them by the way when I modify the related content. Of course
you are very welcome to fix things you think should be fixed. Just it
would be nice if you can notify me before you start to fix them. Because
I am still making a lot of changes, which always have a lot of conflicts
with some small changes you and Linas fixed, and because they usually
occurred on a lot of codes I had modified or just deleted, so I always
cannot merge them... Recently I just spent hours to fix all the
conflicts. If they are not very very important / core or emergent, maybe
we can postpone all the cleanups until I finish the current pattern
mining work stage?
Sure no problem, just notify me when you are done with work on the
pattern miner.
I picked some instances from the corpus you gave me early to experiment
with the new interestingness evaluation for them.
More will come soon (end of this week I think).
Thanks,
Nil
Thanks,
Shujing

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
<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,
Shujing

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")
