🗂️ @dxo/data

Developer preview — API unstable (0.0.x).

Datasets and batching for DXO. Pure TypeScript over @dxo/core.

Contract (0.0.5)

| API | Behavior | |--------------------------------------------|-------------------------------------------------------------| | Sample | Flat x (+ optional y) with explicit xShape / yShape | | dataset(samples) | Sync Iterable<Sample> | | batch(samples, { batchSize, dropLast? }) | Sync batches; stacks on a new leading dim | | batchAsync(samples, options) | Same for AsyncIterable | | DataLoader | Thin alias helper around batch / batchAsync |

Not included: shuffle sampler, multi-worker, Prefetch, real MNIST download.

import { batch, dataset } from '@dxo/data';

const ds = dataset([
  { x: [1, 0], xShape: [2], y: [1], yShape: [1] },
  { x: [0, 1], xShape: [2], y: [0], yShape: [1] },
]);

for (const { x, y } of batch(ds, { batchSize: 2 })) {
  // x.shape === [2, 2]
}
