Compare trajectory detectors by content coherence

Runs sniff_trajectory_coherence() on each named flow, across every content signal and the chosen profile(s), and reports which detector produces the more content-coherent partition, whether the signals agree, and the contested nodes (those a pair of detectors place in different final groups).

Usage

sniff_trajectory_comparison(
  flows,
  content,
  profile = "incremental",
  signals = names(content)
)

Arguments

flows

Named list of birddog_flow objects, e.g. list(flow = ..., channel = ...).

content

Named list of (document_id, feature) data frames (see sniff_trajectory_coherence()).

profile

Passed to sniff_trajectory_coherence() (default "incremental").

signals

Which names(content) to score (default all).

Value

A sniff_trajectory_comparison object: a list with summary (per method x signal x profile x resolution), verdict (best_method, delta per signal x profile x resolution), agreement (do all signals pick the same best_method, per profile x resolution), and contested (nodes the detectors place in different final groups, with each method's final_group and silhouette, plus the closer_method; NULL unless exactly two flows are given).
