In CamaraLab/RayleighSelection: An R package for feature selection in topological spaces.

Plot Example

Create and plot a simple nerve complex from an open cover, then compute the Combinatorial Laplacian score of a hardcoded binary feature

library(RayleighSelection)

Compute the nerve complex of an open cover

gy <- nerve_complex(list(c(1,4,6,10), c(1,2,7), c(2,3,8), c(3,4,9,10), c(4,5)))

Plot nerve complex

plot_skeleton(gy)

## [1] "Convergence reached at step 779"

Compute 0-form and 1-form Comb. Lap. scores, p-value, and q-value

For the given binary feature on points

rayleigh_selection(gy,t(as.data.frame(c(0,1,1,0,0,0,0,0,0,1))))

##                                        R0    p0    q0        R1   p1   q1
## c(0, 1, 1, 0, 0, 0, 0, 0, 0, 1) 0.9584665 0.445 0.445 0.5536398 0.16 0.16
