graph_motif_count — CONNGRAPH stats op

• Data kinds: conn_graph → measurement

• Call: import fullseye as fs; fs.ledger.graph_motif_count(W: 'Any', motif: 'str' = 'ffl') -> 'float' (to call the implementation directly, import conngraph; conngraph.graph_motif_count(W: 'Any', motif: 'str' = 'ffl') -> 'float'; from the registry, opsconngraph.get("graph_motif_count"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

3 点モチーフの個数(二値有向、対角は除く): reciprocal / ffl / cycle3。

reciprocal = 相互結合の対の数 (Σ A∧Aᵀ)/2、ffl = Σ_ac (A²)_ac A_ac

(a→b, b→c, a→c)、cycle3 = tr(A³)/3。各インスタンスを 1 回だけ数える。
