Description

Predicts diffusion map projection from new data points

Usage

1
diffuseProj(dm, x, data, distfun)

Arguments

dm

Output from diffuseMat2 function

x

Matrix of new data points. Features in rows and cells in columns.

data

Original data used to generate diffusion map

distfun

A distance function that takes new data as first paramter and previous data as second variable returning a squared distance measure, with each sample in the rows and distance to previous data points in columns, e.g. function(x, y) (1 - cor(x, y))^2.
