Warwick-STEM
Warwick STEM Dataset (WebDataset)
A collection of 19,769 experimental scanning transmission electron microscopy (STEM) images from the University of Warwick, spanning hundreds of diverse materials projects collected between 2010 and 2018.
Dataset Description
This dataset contains experimental STEM images originally published as part of the Warwick Electron Microscopy Datasets by Jeffrey Ede. The images cover a wide range of materials and imaging conditions, making them… See the full description on the dataset page: https://huggingface.co/datasets/Stemson-AI/Warwick-STEM.STEM2Crystal-Bench
STEM2Crystal-Bench
STEM2Crystal-Bench is the benchmark for the paper "From Noisy STEM to Crystal Structure: Evidence-Structure CoDiffusion under Composition Constraints" (Chen & You, KDD 2026, Oral), which introduces STEM2Crystal CoDiffusion (SCCD). It evaluates methods that reconstruct a crystal structure from a noisy STEM image when the composition is known. The release has a large synthetic set with controlled noise and a small set of real STEM images, with ground-truth CIFs… See the full description on the dataset page: https://huggingface.co/datasets/gary23ai/STEM2Crystal-Bench.STEM2Mat
AutoMat Benchmark: STEM Image to Crystal Structure
The AutoMat Benchmark is a multimodal dataset designed to evaluate deep‑learning systems for iDPC-STEM‑based crystal‑structure reconstruction and property prediction.

STEM Diagrams
30,325 technical diagrams (block diagrams, schematics, flowcharts, architectures)
extracted from arXiv papers across six engineering fields, each with a source
attribution and a quality score. Built by an LLM-curated pipeline and used to show
that a small frozen-feature classifier can replace the paid LLM labeling gate.

Why This Dataset
Post-training with RL is now the primary driver of frontier model improvement. The bottleneck is finding data at the right difficulty for current SOTA models. MMLU is saturated (>90%). HLE, once considered unsolvable, is now… See the full description on the dataset page: https://huggingface.co/datasets/TuringEnterprises/Multimodal-STEM-HLE-plus-plus.Stembind

Dataset card for Multi-modal LUCAS
Dataset summary
Multi-modal LUCAS aims at being a curated vision-language dataset from LUCAS survey data and in-situ field photos. LUCAS (Land Use/Cover Area Frame statistical Survey) is a land-monitoring exercise conducted by EUROSTAT in close cooperation with the Directorate-General responsible for Agriculture, with technical support from the Joint Research Centre (JRC). The survey has been repeated every three years since 2006… See the full description on the dataset page: https://huggingface.co/datasets/stemauro/multimodal-lucas.STEM-en-ms
