# sf.apps.train.prob_photon_sample¶

prob_photon_sample(A, sample)[source]

Calculate the probability of a sample of photon counts.

The input adjacency matrix must have singular values not exceeding one. This can be achieved by rescaling an arbitrary adjacency matrix using rescale_adjacency().

Parameters
• A (array) – the adjacency matrix

• sample (array) – the sample

Returns

the probability

Return type

float
