Image-to-Video Quality-Scored Clips
A collection of prompted image-to-video samples with quality-evaluation metadata.
Each sample pairs a first frame (the I2V conditioning image) with one or both
of:
a generated video produced by a video model from the first frame + prompt
an original clip (the reference/source video the prompt was authored around)
A subset of the samples also carry per-clip quality scores: an overall
quality_score, six per-aspect breakdowns… See the full description on the dataset page: https://huggingface.co/datasets/mohantesting/video-quality-scored.quality

Creative Writing - Part One (Shadow & Skeleton)
This dataset is designed to train Large Language Models (LLMs) in grounded creative writing by enforcing a "Think-Before-You-Write" methodology.
Methodology: Shadow & Skeleton
Most creative writing datasets train models to produce "vibes" or "cinematic descriptions" that often lack physical coherence or psychological depth. This dataset takes a different approach:

📘 FineWeb-Edu-Quality4plus
Overview
FineWeb-Edu-Quality4plus is a high-quality filtered subset of the original
HuggingFaceFW/fineweb-edu dataset (ODC-By License).
This subset retains only samples with:
quality_score ≥ 4
The goal is to provide a cleaner and more reliable dataset suitable for
language model pre-training, instruction tuning, education-related NLP,
and quality-sensitive downstream tasks.
This work is independent and not affiliated with the official FineWeb… See the full description on the dataset page: https://huggingface.co/datasets/Morton-Li/FineWeb-Edu-Quality4plus.high-quality-invoice-images-for-ocr
