Hi @erikerlandson and @rnowling,
Thank you for your advice.
I modified my code. Would you please review it.
- Improve the performance of calculating distance metric to use Breeze
- Add Weighted trait for general weighted distance metric
ex) class WeightedEuclideanDistanceMetric(val weight: Vector) extends
DistsanceMetric with Weighted
I think it's a bit tricky to calculate distance metric because of Weighted
trait.
I'd like to get your thoughts on it.
