pyhctsa.operations.symbolic.coarse_grain(y, how_to_cg, num_groups)¶

Coarse-grains a continuous time series to a discrete alphabet.

Parameters:¶

y : array-like¶

The input time series.

how_to_cg : str¶

The method of coarse-graining. Options:

• ’updown’

• ’quantile’

• ’embed2quadrants’

• ’embed2octants’

num_groups : int¶

Specifies the size of the alphabet for ‘quantile’ and ‘updown’, or sets the time delay for the embedding subroutines.

Returns:¶

yth – The coarse-grained time series.

Return type:¶

array-like
