graph_edge_consensus — GRAPH population op

• 数据种类:table → table

• 调用: import fullseye as fs; fs.ledger.graph_edge_consensus(adjs, ordered=False, n_null=0, swaps_per_edge=5, seed=0)(要直接调用实现,import graphinv; graphinv.graph_edge_consensus(adjs, ordered=False, n_null=0, swaps_per_edge=5, seed=0);从台账取用则 opsgraph.get("graph_edge_consensus"))

用法

> 该算子的说明尚无译文,以下照原文给出。

How many individuals share each connection — K wiring matrices on one node order.

`adjs is either a list of K square matrices or a table {name: matrix}` (its

insertion order is the individual order), all on the same node order (align

the cell names first; a node absent from an individual is a zero row and column).

Weights (synapse counts) are kept for the synapse shares; presence is `> 0`.

Self-loops are dropped.

Returns a dict with:

• `k (K), n, names, edges_per_individual and union` (edges

seen in at least one individual)

• `occupancy_hist — h[c] = number of edges present in exactly c`

individuals, `c = 0..K (h[0]` is always 0: only the union is counted)

• `jaccard — the K x K pairwise overlap |Ei ∩ Ej| / |Ei ∪ Ej|`

• `synapse_share — for each c`, the fraction of all synapses (summed over

individuals) on edges of occupancy `c` (with a 0/1 input: the edge share)

• with `ordered=True` (individuals listed in developmental order): the union is

split by its presence pattern along the order into `stable` (present in all),

`added (absent, then present to the end: 0..01..1), lost`

(`1..10..0) and flicker (anything else). The four sum to union`.

• with `n_null >= 2`: every individual is rewired independently by

degree-preserving swaps (each node's in/out degree kept exactly, checked per

sample, fail-closed) and the occupancy histogram is re-counted. Reports

`occupancy_null_mean / occupancy_null_sd per c` and

`shared_all_ratio` (edges present in all K, observed over the null mean; inf

when the null never shares one, so `shared_all_null_max` is reported too):

the chance level of "the same connection in every animal" given only each

animal's degrees.

Identities (the tests are built on these, not on fitted numbers):

`sum_c c * h[c] == sum_i |E_i|; sum_c h[c] == union`; K identical inputs give

`h[K] == union` and every Jaccard == 1; the Jaccard matrix is symmetric with a unit

diagonal; `stable + added + lost + flicker == union; synapse_share` sums to 1.

Raises `ValueError: adjs` not a list / table; fewer than 2 individuals;

matrices of different sizes; any refusal of :func:graph_degree_summary

(non-square, negative, non-finite, string / bool / complex / masked input); an

individual with no edges; `n_null` equal to 1 (no spread) or negative;

`swaps_per_edge < 1`.
