Our Data Analysis Methods include:


  • Identify patterns and outliers within numerical, text, or sequence-based data sets.
  • Use AI/ML algorithms and experimental design.
  • Data processing (e.g. feature engineering, transformation, normalization and imputation)
  • Developing and evaluating supervised and unsupervised machine learning models.
  • Variable ranking and prioritization.
  • Deep Learning and AI approaches.
  • Reproducible data science workflows.
  • Statistical Testing and Power Analysis.
