scalex.metrics.batch_entropy_mixing_score(data, batches, n_neighbors=100, n_pools=100, n_samples_per_pool=100)

Calculate batch entropy mixing score

Algorithm

• 1. Calculate the regional mixing entropies at the location of 100 randomly chosen cells from all batches

• 2. Define 100 nearest neighbors for each randomly chosen cell

• 3. Calculate the mean mixing entropy as the mean of the regional entropies

• 4. Repeat above procedure for 100 iterations with different randomly chosen cells.

type data:

param data:

np.array of shape nsamples x nfeatures.

type batches:

param batches:

batch labels of nsamples.

type n_neighbors:

param n_neighbors:

The number of nearest neighbors for each randomly chosen cell. By default, n_neighbors=100.
