Dataset Summary
Documents from the Royal Danish Library published between 1750 and 1930.
The dataset has each page of each document in image and text format. The text was extracted with OCR.
The documents (books of various genres) were obtained from the library. The dataset was assembled to make these public domain Danish texts more accessible.… See the full description on the dataset page: https://huggingface.co/datasets/chcaa/kb-books.tahoe-100m-zarr
Tahoe-100M Zarr Collection
Production-ready tahoe single-cell RNA-seq data exported from Arc Virtual Cell Atlas (Tahoe-100M) into native Zarr stores for chunked, on-demand access on the Hugging Face Hub.
Why Zarr
Single-cell expression matrices get impractical fast if you treat them like ordinary dense files. Zarr is the point of this repo: it makes large atlas-scale data usable without forcing users to download or materialize the whole matrix before they can do anything… See the full description on the dataset page: https://huggingface.co/datasets/KokosDev/tahoe-100m-zarr.K2Datasets

Dataset Card for Omni-MATH
Recent advancements in AI, particularly in large language models (LLMs), have led to significant breakthroughs in mathematical reasoning capabilities. However, existing benchmarks like GSM8K or MATH are now being solved with high accuracy (e.g., OpenAI o1 achieves 94.8% on MATH dataset), indicating their inadequacy for truly challenging these models. To mitigate this limitation, we propose a comprehensive and challenging benchmark specifically designed… See the full description on the dataset page: https://huggingface.co/datasets/KbsdJames/Omni-MATH.KodCode-V1

ClimbLab-Ja
ClimbLab-Ja is a high-quality 300-billion-token Japanese corpus with 20 clusters. It is a Japanese adaptation of the nvidia/Nemotron-ClimbLab approach. Based on LLM-jp Corpus v4, we semantically reorganized and filtered the dataset into 20 distinct clusters, resulting in a high-quality 300-billion-token corpus. Specifically, we first grouped the data into 1,000 groups based on topic information. Then we assigned six scores from 0 to 5 to each group… See the full description on the dataset page: https://huggingface.co/datasets/KantaHayashiAI/ClimbLab-Ja.Raon-OpenTTS-Pool

KMMLU (Korean-MMLU)
We propose KMMLU, a new Korean benchmark with 35,030 expert-level multiple-choice questions across 45 subjects ranging from humanities to STEM.
Unlike previous Korean benchmarks that are translated from existing English benchmarks, KMMLU is collected from original Korean exams, capturing linguistic and cultural aspects of the Korean language.
We test 26 publically available and proprietary LLMs, identifying significant room for improvement.
