ret-sample — reasoning-retrieval query→positive pairs

Composed-image-retrieval (CIR) style pairs: a query image + instruction retrieves a target image. Images are embedded directly in the parquet, so nothing external is needed to train or browse.

  • 3,127 pairs · 8 shards · 341 MB
  • Built for williamium3000/Qwenvl2d5 (ret-streaming-retsample branch) and streamable by it with no S3 credentials.

Columns

column type meaning
q_image Image() query image (PIL on access; stored as original JPEG bytes)
pos_image Image() positive/target image
instruction string the query instruction (what to retrieve)
caption string caption of the positive
q_key, pos_key string blake3(raw file bytes)[:16] content ids
group_id int near-duplicate cluster id (teacher cosine ≥ 0.98)
n_text_tokens int exact instruction length, Qwen2.5-VL tokenizer
task, subset string cir; source subset (results / instruct / …)

Usage

from datasets import load_dataset
ds = load_dataset("Icey444/ret-sample", split="train")
r = ds[0]
r["q_image"]        # PIL.Image
r["instruction"]    # "What would I need to use to navigate through a place like this?"
r["pos_image"]      # PIL.Image

Training (in the repo above):

bash scripts/sft_ret_sample_streaming.sh     # --dataset ret_sample%100

Notes

  • No hard negatives. The training code uses in-batch InfoNCE; its collator explicitly cannot take a 3rd item per instance, so mined negatives would be carried and never read.
  • Images are stored undecoded and decoded to PIL once at preprocess time — lossless (verified byte-identical through the pipeline) and no per-epoch re-encode.
  • Source images originate from jeffrey/reasoning_retrieval on the zillion2 store; the _key columns are content hashes of those exact bytes.
