Get Consensus Features from Best Signature

Extract the consensus feature set from the selected best signature(s). Aggregates features selected across outer folds.

Usage

get_consensus_features(nested_result, best_signature, min_frequency = 0.5)

Arguments

nested_result

A NestedCVResult object

best_signature

Result from select_best_signature() or learner_id string

min_frequency

Minimum proportion of folds where feature must be selected (default: 0.5)

Value

A data.table with columns: feature, frequency, selected (TRUE if >= min_frequency)

Examples

if (FALSE) { # \dontrun{
best <- select_best_signature(result)
consensus <- get_consensus_features(result, best, min_frequency = 0.8)
final_features <- consensus[selected == TRUE]$feature
} # }
