Pads sequences to the same length
pad_sequences(
sequences,
maxlen = NULL,
dtype = "int32",
padding = "pre",
truncating = "pre",
value = 0
)Matrix with dimensions (number_of_sequences, maxlen)
List of lists where each element is a sequence
int, maximum length of all sequences
type of the output sequences
'pre' or 'post', pad either before or after each sequence.
'pre' or 'post', remove values from sequences larger than maxlen either in the beginning or in the end of the sequence
float, padding value
This function transforms a list of num_samples sequences (lists
of integers) into a matrix of shape (num_samples, num_timesteps).
num_timesteps is either the maxlen argument if provided, or the length
of the longest sequence otherwise.
Sequences that are shorter than num_timesteps are padded with value at
the end.
Sequences longer than num_timesteps are truncated so that they fit the
desired length. The position where padding or truncation happens is
determined by the arguments padding and truncating, respectively.
Pre-padding is the default.
