the implicit conversion function doesn't have to throw an exception, it
just needs to override the breeze vector overloading and inherit the default
spark vector overloading as usual:
implicit def functionToDistanceMeasure(f: (BV[Double], BV[Double]) =>
Double): DistanceMeasure = new DistanceMeasure {
override def apply(v1: BV[Double], v2: BV[Double]): Double = f(v1,
v2)
}
I guess there also needs to be a `functionToDistanceMetric`
Aside from that I think it is looking good. Thank you for your work on
this!
