DataLoader<T> class

Yields fixed-size batches of items from a Dataset.

  • batchSize — items per batch.
  • shuffle — reshuffle the index order at every call to batches. Uses seed for determinism.
  • dropLast — drop the trailing short batch when dataset.length % batchSize != 0. Default keeps it.
