Validate and inspect feature maps

Usage

validate_feature_map(x)

feature_map_source_space(x)

feature_map_target_space(x)

feature_map_operator(x)

feature_map_digest(x)

Arguments

x: A feature_map.

Value

validate_feature_map() returns x invisibly. The accessors return the source space, target space, linear operator, or deterministic digest.

Examples

src <- index_space(4, ids = paste0("v", 1:4), namespace = "map-source")
tgt <- index_space(2, ids = paste0("p", 1:2), namespace = "map-target")
op <- matrix(c(0.5, 0.5, 0, 0, 0, 0, 0.5, 0.5), nrow = 2, byrow = TRUE)
m <- feature_map(src, tgt, op, map_type = "toy_aggregation")
