Changelog:
2025.04.17 (hash: NOT YET RELEASED):
We have changed the Yb default pseudopotential to Yb_3 from VASP, this is the same that Materials Project uses. In the previous version we had kept it as Yb, and Materials Project had to Yb-containing materials. Alexandria and OQMD uses Yb. As a result no Yb-containing materials are… See the full description on the dataset page: https://huggingface.co/datasets/LeMaterial/LeMat-Bulk.s2orc_small

Roleplaying forum scrapes (raw)
Here are mostly original/raw files for some of the roleplaying forums I scraped in the past (and some newly scraped ones), repacked as HTML strings + some metadata on a one-row-per-thread basis instead of a one-row-per-message basis, which should make them more convenient to handle.
Unlike the previously uploaded archive, they shouldn't have issues with spaces between adjacent HTML tags, as that occurred by mistake in an intermediate processing step… See the full description on the dataset page: https://huggingface.co/datasets/lemonilia/roleplaying-forums-raw.lemexp-task1-v2EasyJailbreak_Datasetslemonlemexp-task1LeMat-GenBench-embeddingslemon_into_bowlThis dataset was created using LeRobot.

LEM-benchmarks
Canonical 8-PAC benchmark results for the Lemma model family.
This dataset is an aggregated store of per-round evaluation data produced by
lthn/LEM-Eval. Every row
represents one model's answer to one question in one round of a paired A/B
run against its unmodified base, and the dataset grows monotonically as more
workers contribute — different machines, different sampling states, different
hardware paths — which is the whole point of 8-PAC: multiple independent… See the full description on the dataset page: https://huggingface.co/datasets/lthn/LEM-benchmarks.lemexp-task1-v2-eval-resultspick_lemon_and_drop_in_bowlThis dataset was created using LeRobot.

Giant in the Playground (roleplaying subforums only)
A semi-cleaned, processed version of the raw files uploaded elsewhere of the roleplaying sections (Play-by-Post Games) from Giant in the Playground, scraped on January 2025. I've made an effort to preserve as much as possible of the original HTML while simplifying and converting it to HTML5 where possible and cleaning it, with the notable exception of converting HTML linebreaks into newlines.
