A continuously growing tabular pretraining corpus for the Tabula foundation model (tabPFN-style in-context learning). Built by an autonomous agent that alternates between harvesting permissively-licensed real datasets and generating high-quality synthetic ones.

Usage

from datasets import load_dataset

# Load a specific batch config
ds = load_dataset("avewright/tabula-pretraining-corpus", name="datagen_001")

# Load all configs
from huggingface_hub import HfApi
api = HfApi()
# List available configs by checking repo folders

Each config represents a batch with its own column schema (different domains have different feature names). Load configs individually rather than all at once.

Schema

Every row has feature columns plus _source_meta (JSON string):

batch_id, source_type, source_id, domain, task_type, license, citation_key
