Shuffles 0..n-1 once with the reference LCG Fisher-Yates, then slices
into consecutive batches of b. Returned indices are 0-based.
Usage
morie_geron_dataloader_minibatch(
n,
b,
shuffle = TRUE,
seed = 0,
drop_last = FALSE
)
Arguments
- n
Number of instances.
- b
Batch size in [1, n].
- shuffle
Logical; permute before slicing.
- seed
LCG seed.
- drop_last
Drop a short final batch.
Value
List with batches (list of 0-based index vectors),
n_batches, batch_sizes, permutation, covers_all.
Examples
morie_geron_dataloader_minibatch(n = 5L, b = 5L)
