FLAME2 RGB-IR Smoke Dataset
This Hugging Face dataset was prepared from a Kaggle mirror of FLAME2 RGB/thermal frame pairs.
Columns:
rgb: RGB image
ir: thermal/IR image
label: int64, where 0 = without smoke and 1 = with smoke
Labels are derived from the original FLAME2 Frame Pair Labels.txt smoke ranges when available.

solar-flare-hmi-datasplitsThis dataset is intended to be used for training/testing solar flare forecasting models. It contains various data splits (in json format) of SDO/HMI magnetogram images compiled by
Boucheron, L.E., et al., 2023, Sci Data 10, 825, https://doi.org/10.1038/s41597-023-02628-8.
Splits "train", "val", "test" corresponds to the original data splits provided by Boucheron et al., while the other splits are created by downsampling the No-Flare and C flare class to obtain
more balanced splits and… See the full description on the dataset page: https://huggingface.co/datasets/inaf-oact-ai/solar-flare-hmi-datasplits.FLARE-MLLM-2D

Country Flag Variations (Flux 2-dev, image-verified)
Synthetic flag images generated with Flux 2-dev from the prompt
"The national flag of {country}", then filtered by a strict
image-to-image verification against official reference flags.
Dataset summary
71 countries, 1395 images
Each country has 15-20 verified images (originally 20 per country;
images that disagreed with the reference flag were removed)
Split: per-country 80 / 20 train/val (deterministic by sorted seed)… See the full description on the dataset page: https://huggingface.co/datasets/tokeron/country-flags-variations.country-flags-dataset
