breeze KMeans vs nak KMeans ?

[vivace]

Hi

I have been running KMeans with nak. As per the example I do something like:

  val kmeans = new Kmeans[SparseVector[Double]](

    sparseExamples.toIndexedSeq,

    distanceFun,

    minChangeInDispersion=0.0000001,

    maxIterations=10

  )

I wanted to then plot some things and experiment with breeze-viz so i included the dependencies :

"org.scalanlp" % "breeze_2.10" % "0.9",

 "org.scalanlp" % "breeze-natives_2.10" % "0.9",

  

However now i am finding this error: 

could not find implicit value for parameter space: breeze.math.MutableInnerProductSpace[breeze.linalg.SparseVector[Double],Double]

[error] Error occurred in an application involving default arguments.

[error]   val kmeans = new Kmeans[SparseVector[Double]](

So my question is where can i get this implicit MutableInnerProductSpace?

[David Hall]

Don't use Breeze 0.9 with Nak right now. Use 0.8.1. We renamed MutableInnerProductSpace to MutableInnerProductVectorSpace in 0.9, and haven't updated Nak yet.

Thanks 

how about breeze-viz ?

i keep getting this error:

I haven't released a new Breeze-Viz yet, sorry. This week or this weekend.

ok no prob -- thanks

ok, breeze-viz release is cut and pushed to sonatype. Nak is going to be a bit of a pain, and it's probably going to need to wait on 0.9.1, because most of the changes that effect Nak from 0.8 to 0.9 are going to change again between 0.9 and 0.9.1... and I don't feel like doing the changes twice. :-)

0.9.1 should be out soonish, in a week or two.

great, thanks so much!!

I have an updated Nak that works with the master branch of breeze, although currently it'smixed in with a feature branch. I can separate some of it out though and push that when it's needed.

Does this Nak version have the kNearestNeighbors as well :)) if so that would be awesome. :)
