The logic for transformation is based on thresholding and avoids jumping from 0 to 1 inadvertently. Example: >>> binarizer = Binarize(threshold=0.5, stability=3, sample_rate=1) >>> inputs=torch.Tensor([0.1, 0.6, 0.2, 0.6, 0.1, 0.1, 0.1, 0.7, 0.7, 0.7, 0.7, 0.7, 0.7, 0.1]) >>> # |------------------|-------------|----------------------------|----| >>> # unstable stable stable irregularity >>> result = binarizer(inputs.unsqueeze(0).unsqueeze(0)) >>> print(result) tensor([[[0., 0., 0., 0., 0., 0., 0., 1., 1., 1., 1., 1., 1., 1.]]]) ?皙?@cs t||_||_||_dS)a Args: threshold (float): if x > threshold 0 else 1 stability (float): Minimum number of seconds of 0 (or 1) required to change from 1 (or 0) to 0 (or 1) sample_rate (int): The sample rate of the wave form N)super__init__ threshold stability sample_rate)selfr r r  __class__E/home/ubuntu/.local/lib/python3.10/site-packages/asteroid/binarize.pyrs  zBinarize.__init__cCs4||jk}|d}t|}t||j|j}|S)N)r squeezetolistcount_same_pairtransform_to_binary_sequencer r )r xactivepairsrrrforward"s zBinarize.forward)rrr)__name__ __module__ __qualname____doc__rr __classcell__rrr rrs rcCs*g}|D]}|ddt|Dq|S)a~Transform a list of 0 and 1 in a list of (value, num_consecutive_occurences).
