Overview

This PR enhances the documentation quality across all Jupyter notebooks in the repository by fixing spelling/grammar errors and improving markdown clarity and conciseness.

Changes Made

Spelling & Grammar Fixes

  • Fixed typos: auxilliaryauxiliary, obvservationobservation, suprisingsurprising
  • Corrected grammar: "competing the tournament" → "competing in the tournament"
  • Fixed technical term: PeasonPearson
  • Standardized parameter naming for consistency

Markdown Improvements

Enhanced readability and professionalism across all notebook markdown cells:

hello_numerai.ipynb

  • Streamlined dataset descriptions and feature set explanations
  • Clarified training data, eras, targets, and features documentation
  • Improved modeling and performance evaluation sections

feature_neutralization.ipynb

  • Refined feature risk and exposure explanations
  • Enhanced neutralization application and performance impact descriptions
  • Improved group neutralization comparison sections

target_ensemble.ipynb

  • Clarified auxiliary targets and ensemble creation documentation
  • Enhanced model training and performance evaluation sections
  • Improved benchmark model discussions

signals/example_model.ipynb

  • Streamlined tickers, technical indicators, and modeling documentation
  • Enhanced scores and alpha calculation explanations

Formatting Enhancements

  • Replaced verbose explanations with concise, professional language
  • Added bullet points and numbered lists for better structure
  • Used bold text for emphasis on key concepts
  • Maintained complete technical accuracy throughout

Impact

These changes improve the onboarding experience for new users and make the documentation more professional and maintainable, while preserving all technical content and accuracy.

Files Changed

  • hello_numerai.ipynb (root & numerai/)
  • feature_neutralization.ipynb (root & numerai/)
  • target_ensemble.ipynb (root & numerai/)
  • signals/example_model.ipynb
  • example_model.ipynb

- Fix "auxilliary" → "auxiliary" (12 occurrences)
- Fix "auxilary" → "auxiliary" (2 occurrences)
- Fix "obvservation" → "observation" (2 occurrences)
- Fix "suprising" → "surprising" (2 occurrences)
- Fix "competing the tournament" → "competing in the tournament" (2 occurrences)
- Fix "Peason" → "Pearson" correlation (1 occurrence)
- Standardize parameter naming: _live_benchmark_models → live_benchmark_models

Affected notebooks:
- example_model.ipynb
- feature_neutralization.ipynb
- hello_numerai.ipynb
- numerai/feature_neutralization.ipynb
- numerai/hello_numerai.ipynb
- numerai/target_ensemble.ipynb
- target_ensemble.ipynb
Improved all markdown cells to be more concise, professional, and well-formatted:

- hello_numerai.ipynb: Enhanced dataset descriptions, feature set explanations,
  training data sections, eras/targets/features documentation, modeling sections,
  and performance evaluation content

- feature_neutralization.ipynb: Refined feature risk explanations, feature groups
  descriptions, exposure calculations, neutralization application, performance
  impact analysis, and group neutralization comparisons

- target_ensemble.ipynb: Improved auxiliary targets descriptions, target names/
  values/correlations, model training sections, performance evaluations, ensemble
  creation and evaluation, and benchmark model discussions

- signals/example_model.ipynb: Enhanced tickers section, bloomberg mappings,
  technical indicators documentation, modeling descriptions, scores explanations,
  and alpha calculations

Applied same improvements to numerai/ folder duplicates for consistency.

Changes focus on:
- Making descriptions more concise and direct
- Improving formatting with bullets and numbered lists
- Adding emphasis with bold text for key concepts
- Maintaining technical accuracy while enhancing readability
- Ensuring professional tone throughout
