Type Members

1. class BigToSmall extends MatrixJoiner

2. class BlockMatrix[RowT, GroupT, ColT, ValT] extends AnyRef

   BlockMatrix is 3 dimensional matrix where the rows are grouped It is useful for when we want to multiply groups of vectors only between themselves.

3. class ColVector[RowT, ValT] extends Serializable with WrappedPipe

4. class DefaultMatrixJoiner extends MatrixJoiner2

   This uses standard join if the matrices are comparable size and large, otherwise, if one is much smaller than the other, we use a hash join

5. sealed trait Degree extends AnyRef

6. class DiagonalMatrix[IdxT, ValT] extends WrappedPipe with Serializable

7. class DimsumInCosine[N] extends TypedSimilarity[N, (Weight, L2Norm), Double]

8. class DiscoInCosine[N] extends TypedSimilarity[N, InDegree, Double]

   Params: minCos: the minimum cosine similarity you care about accuracy for delta: the error on the approximated cosine (e.

9. case class Edge[+N, +E](from: N, to: N, data: E) extends scala.Product with Serializable

   Represents an Edge in a graph with some edge data

10. class ExactInCosine[N] extends TypedSimilarity[N, InDegree, Double]

    This algothm is just matrix multiplication done by hand to make it clearer when we do the sampling implementation
