ALEA Data Generator

This is a basic synthetic data generation/perturbation library designed to support the creation or augmentation designed by the ALEA Institute to support the creation and augmentation of data without relying on "tainted" LLMs.

Data generation techniques in this library:

• do not require the use of any LLM or external data source
• can be used with KL3M, our Fairly Trained LLM

Supported Patterns

The following data generation patterns are supported:

• Simple string templates with sampled values (e.g., This Agreement, by and between <|company:a|> and <|company:b|>, is made as of <|date|>.)
  • Faker integration for common data types (e.g., names, addresses, dates, etc.)
• Large templates with sampled values (e.g., jinja2 templates in files)
• Common document types (e.g., emails, contracts, memos, etc. using templates)
• Data perturbation (e.g., realistic errors introduced by humans, OCR, or other automated systems)
  • Skipping, doubling, or transposing/swapping characters
  • Skipping, doubling, or transposing/swapping tokens
  • QWERTY and mobile keyboard mistakes (off-by-one key, shift errors, etc.)
  • Homophones (e.g., their vs. there)
  • Synonyms (e.g., big vs. large)
  • Negation/antonyms (e.g., big vs. small)
  • Capitalization errors (e.g., big vs. Big)
  • Punctuation errors (e.g., big vs. big.)
  • OCR-like errors (e.g., misreading characters, smudges, etc.) -
• Representation conversion (e.g., 429 to four hundred twenty-nine or four twenty-nine)
• Format conversion (e.g., Markdown <-> HTML variants)

Future Roadmap

• Document image generation for document/OCR models
