Soft-Label Dataset Distillation and Text Dataset Distillation
Bibliographic record
Abstract
Dataset distillation is a method for reducing dataset sizes by learning a small number of representative synthetic samples. This has several benefits such as speeding up model training, reducing energy consumption, and reducing required storage space. These benefits are especially crucial in settings like federated learning where initial overhead costs are justified by the speedup they enable. Currently, 1) each synthetic sample is assigned a single ‘hard’ label, and 2) dataset distillation can only be used with image data. We propose to simultaneously distill both images and their labels, thus assigning each synthetic sample a ‘soft’ label (a distribution of labels). Our algorithm increases accuracy by 2-4% for several image classification tasks. Using ‘soft’ labels also enables distilled datasets to consist of fewer samples than there are classes as each sample encodes information for multiple classes. For example, training a LeNet model with 10 distilled images (one per class) results in over 96% accuracy on MNIST, and almost 92% accuracy when trained on just 5 distilled images. We also extend the dataset distillation algorithm to distill text data. We demonstrate that text distillation outperforms other methods across multiple datasets. For example, models attain almost their original accuracy on the IMDB sentiment analysis task using just 20 distilled sentences.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
