equivariance_check — DRIVE `pegtactile` op

• Data kinds: any × any × signal × scalar × signal → table

• Call: import fullseye as fs; fs.ledger.equivariance_check(render, op, angles, n: 'int', centre) -> 'dict' (to call the implementation directly, import pegtactile; pegtactile.equivariance_check(render, op, angles, n: 'int', centre) -> 'dict'; from the registry, opsdrive.get("equivariance_check"))

Usage

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

同変性の門の部品: 形を角 θ だけ回して描き(`render(θ) → 画像)、知覚 op(op(画像)` → (row, col, 向き))の答えが群の作用

どおりに変わるか。期待 = 位置は `centre` = (row, col) まわりに θ 回る、向きは θ 進む(mod 2π/n、n = 0 なら向きは比べない)。

返り `pos_err_px(最大)、ang_err_deg(最大、mod 2π/n の最短距離、比べなければ nan)、rows`(角ごと)。

Raises ValueError: render・op が呼べない、角が 1 つも無い・有限でない、n < 0、centre が 2 成分でない。
