buildWijMatrix | R Documentation |
Rescale the weights in an edge matrix to match a given perplexity. From 'largeVis', <https://github.com/elbamos/largeVis>
buildWijMatrix(x, threads = NULL, perplexity = 50)
x |
An edgematrix, either an 'edgematrix' object or a sparse matrix. |
threads |
numeric The maximum number of threads to spawn (default=NULL). Determined automatically if NULL (default=NULL) |
perplexity |
numeric Given perplexity (default=50) |
A list
with the following components:
An [N,K] matrix of the distances to the nearest neighbors.
An [N,K] matrix of the node indexes of the neartest neighbors. Note that this matrix is 1-indexed, unlike most other matrices in this package.
The number of nearest neighbors.
