• 'seed' is used for generating a same random sequence. 'shuffle' is used for shuffling something. To shuffle two lists in the same order, this code works : idx = [1, 2, 3, 4, 5, 6] idx2 = [1, 2, 3, 4, 5, 6] seed = np.random.randint(0, 100000) np.random.seed(seed) np.random.shuffle(idx) np.random.seed(seed) np.random.shuffle(idx2)

  • seed: Optional random seed for shuffling and transformations. validation_split: Optional float between 0 and 1, fraction of data to reserve for validation. subset: One of "training" or "validation". Only used if validation_split is set. interpolation: String, the interpolation method used when resizing images. Defaults to bilinear.

  • Mar 06, 2017 · This randomly shuffles the examples in the dataset based on random_state, which is the seed for the random generator. It doesn’t matter what this seed it, but by always using the same seed we create a reproducible experiment. Finally, save the four new arrays in NumPy’s binary file format. We now have a training set and a test set!

Mutual information as measure for coevolution of residues¶. Mutual information (MI) is a broadly used measure for the coevolution between two residues of a sequence 1 originated in information theory.

If int, random_state is the seed used by the random number generator; If RandomState instance, random_state is the random number generator; If None, the random number generator is the RandomState instance used by np.random. shuffle : boolean, optional (default=True) Whether or not to shuffle the data before splitting.
