Iris Species Dataset
The Iris dataset was used in R.A. Fisher's classic 1936 paper, The Use of Multiple Measurements in Taxonomic Problems, and can also be found on the UCI Machine Learning Repository.
It includes three iris species with 50 samples each as well as some properties about each flower. One flower species is linearly separable from the other two, but the other two are not linearly separable from each other.
The dataset is taken from UCI Machine Learning Repository's… See the full description on the dataset page: https://huggingface.co/datasets/scikit-learn/iris.irish_fineweb_eduData translation project of https://huggingface.co/datasets/HuggingFaceFW/fineweb-edu, sample-10BT subset. Data are translated from English to Irish using NLLB-3.3B.

Note
The Iris dataset is one of the most popular datasets used for demonstrating simple classification models. This dataset was copied and transformed from scikit-learn/iris to be more native to huggingface.
Some changes were made to the dataset to save the user from extra lines of data transformation code, notably:
removed id column
species column is casted to ClassLabel (supports ClassLabel.int2str() and ClassLabel.str2int())
cast feature columns from float64 down to float32… See the full description on the dataset page: https://huggingface.co/datasets/hitorilabs/iris.iris-infrared-maps
IRIS Infrared Maps
The Improved Reprocessing of the IRAS Survey (IRIS) provides co-added
infrared sky-brightness maps at 12, 25, 60 and 100 microns. These four
configurations are the authors' native-resolution NSIDE-2048 nohole
HEALPix products, frozen by NASA LAMBDA. HCON1, HCON2 and HCON3 were
co-added, and DIRBE data fill the roughly two per cent of the sky not
observed by IRAS.

Why this dataset exists
SEAI hides this data behind an ASP.NET form button on their BER Research Tool. Click "Download All Data" and you get a 250MB zipped tab-separated file. No API, no static URL you can curl. Annoying.

Dataset Summary
This dataset is a structured and cleaned collection of recipe data derived from the Food.com Recipes and Interactions dataset. It is designed for ingredient-based personalization, machine learning training, and interactive recommendation systems. The dataset integrates a hierarchical ingredient taxonomy, standardized nutrition information, and categorical metadata (e.g., diet tags, cuisine attributes, region) to support downstream… See the full description on the dataset page: https://huggingface.co/datasets/Iris314/recipe-cleaned.irish_blimpTabula_Muris_Senis_10x

Irish Traditional Music Test Data Sets for Machine Learning
The intention of these test data sets is to support development of classification models that perform well for Irish traditional dance music,
which will then support good research on the musical characteristics of this music.
The classification challenge supported here is the classic Cover Song Identification (CSI) aka Version Identification (VI) problem – "what tune is that?" – but focused
on the barely researched area of… See the full description on the dataset page: https://huggingface.co/datasets/alanngnet/irish-tunes-csi.irish_magpie_filtered_v4OpenMed-Irish-CorePII-TrainMix-v1
