Data kinds: descriptortable

Call: import reprconv; reprconv.descriptor_to_table(descriptor) (or opsreprconv.get("descriptor_to_table"))

Usage

Descriptor → a summary `table`. One-way.

次元・ノルム・エネルギー集中(正規化した二乗和の上位 10% が占める割合)を

出す。記述子が「実質何次元使っているか」を見るためのもので、次元だけ多くて

ほぼ全部 0 という失敗を可視化する。

Args:

descriptor: (n,) または (m, n)。

Returns:

dict(`shape / n / l2 / mean / std / min` /

`max / top10pct_energy / nonzero_fraction`)。

Raises:

ValueError: 形状不正 / 非有限。
