A very small package providing the constructor BatchIterator(X; batchsize=…, limit=…) and the function centered_batch_iterator(X; kwargs…), which allow iteration over blocks of columns of X, for any object X supporting 2d indexing and for which the function size is defined.
The function choose_batchsize helps finding a good batch size while controlling memory usage.
The package was originally designed to iterate over samples of an out-of-core dataset.
