R Documentation

Graph filter with the heat kernel: `f(x) = exp(-\beta |x / \lambda_m - a|^b)`

Graph filter with the heat kernel: f(x) = exp(-\beta |x / \lambda_m - a|^b)

heatFilter(x, l.max, order = 1, offset = 0, beta = 30)

`x`	numeric Values to be filtered. Normally, these are graph laplacian engenvalues.
`l.max`	numeric Maximum eigenvalue on the graph (`\lambda_m` in the equation)
`order`	numeric Parameter `b` in the equation. Larger values correspond to the sharper kernel form (default=1). The values should be positive.
`offset`	numeric Mean kernel value (`a` in the equation), must be in [0:1] (default=0)
`beta`	numeric Parameter `\beta` in the equation. Larger values provide stronger smoothing. `\beta=0` corresponds to no smoothing (default=30).
