Need a method to unmarkRecommendationDNR for when a user accidentally clicks to mark DNR and needs to undo it.
I think setting actionWeights should be documented in the readme. It's pretty useful!
So it takes forever to generate everything with a decent dataset. Is there no way to update after specific activity without doing a total regeneration?
Add the ability to make activity calculations configurable while providing a default value with overrides.
Creating better documentation would help a lot, everything seemed to work fine but when asking for a users recommendations I got an empty array. I think I'm missing a function or something.
My score is always undefined.
akin.recommendation.sampleRecommendationsForUser('2ucvsWKrMY9a3mrjh', 10).then((recs, err) => {
console.log('recs', recs);
})
[
{ score: undefined, item: 'qdYpXGDpf2LZAs4Cb' },
{ score: undefined, item: '3Yw9ntZF45J7W2Aii' },
{ score: undefined, item: 'PSPmDCsK62i3q6uMC' },

I also have no itemWeights defined. Is that a problem or is that related? If I'm understanding correctly itemWeights is default 1 right?
