symmetry op• 数据种类:matrix → table
• 调用: import fullseye as fs; fs.ledger.graph_swap_symmetry(adj, pairs)(要直接调用实现,import graphinv; graphinv.graph_swap_symmetry(adj, pairs);从台账取用则 opsgraph.get("graph_swap_symmetry"))
> 该算子的说明尚无译文,以下照原文给出。
How much of the wiring survives exchanging node pairs (a left/right test).
pairs is a sequence of (i, j) index pairs to exchange (each node in at most one pair). The wiring is re-indexed by the exchange and compared with the original:
jaccard = |E ∩ E'| / |E ∪ E'| over directed edges (self-loops removed). Returns a dict with jaccard, shared, union, edges, and n_pairs.
Identities: the identity pairing (or an empty pairs) gives exactly 1.0; applying the exchange twice recovers the original matrix exactly. For the C. elegans hermaphrodite chemical connectome with its 98 named left/right pairs the measured value is 0.470 — half the wiring is not mirrored.
Raises ValueError: as graph_degree_summary; an index out of range; a node appearing in two pairs; a pair of a node with itself.
