AstroClassification and Redshifts Datasets
This dataset was used for the AstroClassification and Redshifts introduced in Connect Later: Improving Fine-tuning for Robustness with Targeted Augmentations. This is a dataset of simulated astronomical time-series (e.g., supernovae, active galactic nuclei), and the task is to classify the object type (AstroClassification) or predict the object's redshift (Redshifts).

slop-classification
Slop classifier dataset
A human-annotated dataset for studying and classifying AI-generated text that people perceive as “AI slop.”
The dataset is built from samples collected from existing public datasets and annotated through the Bench Labs SlopFinder interface.
Slop score
Each sample receives a score based on human votes:
-1 = definitely slop
0 = undecided / neutral
+1 = not slop at all
The score represents human judgment, not an objective measure of quality… See the full description on the dataset page: https://huggingface.co/datasets/bench-labs/slop-classification.wos_hierarchical_multi_label_text_classificationIntroduced by du Toit and Dunaiski (2024) Introducing Three New Benchmark Datasets for Hierarchical Text Classification.
The WOS Hierarchical Text Classification are three dataset variants created from Web of Science (WOS) title and abstract data categorised into a hierarchical, multi-label class structure. The aim of the sampling and filtering methodology used was to create well-balanced class distributions (at chosen hierarchical levels).
