graph_layer_propagate — CONNGRAPH dimension op

• Data kinds: conn_graph × labels × matrix → matrix

• Call: import fullseye as fs; fs.ledger.graph_layer_propagate(W: 'Any', labels: 'Any', U: 'Any', activation: 'str' = 'kwta', active_frac: 'float' = 0.1, gain: 'float' = 1.0) -> 'np.ndarray' (to call the implementation directly, import conngraph; conngraph.graph_layer_propagate(W: 'Any', labels: 'Any', U: 'Any', activation: 'str' = 'kwta', active_frac: 'float' = 0.1, gain: 'float' = 1.0) -> 'np.ndarray'; from the registry, opsconngraph.get("graph_layer_propagate"))

Usage

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

層 0 の状態 `U (N, n_0) を、ブロック W[layer a → layer a+1]` で前向きに一段ずつ通した全層の状態

`(N, n)(matrix、列はノード順で層 0 の列は U` そのもの)。

受け手ごとに入力重みの和を 1 に正規化してから重みつき和を取り(層の大きさに依らない)、`activation` で

活性化する: `"linear" はそのまま(平均絶対値を gain に)、"tanh" は飽和、"kwta"` は各刺激で

入力が上位 `active_frac` の受け手だけが(閾値上の余剰で)発火し、平均が 1 になるよう正規化する。

層をまたぐ結線(層 a → a+2)と層内の再帰は使わない(前向きの一段ごとの写像だけを見る道具)。
