Feature Generation Algorithm

A Feature Generation Algorithm is a data processing algorithm that can be implemented by a feature generation system to solve feature generation task (sot create new ML features).

• Context:
  • It can support ML Predictive Quality Improvements and Data Preprocessing Processing Improvements.
  • It can involve techniques such as Feature Extraction, Feature Selection, and Dimensionality Reduction.
  • It can be critical in domains where raw data is complex and high-dimensional.
  • It can use domain knowledge to create features that are more relevant to specific Machine Learning Tasks.
  • ...
• Example(s):
  • In text mining, a feature generation algorithm might extract n-grams or sentiment scores from raw text.
  • In finance, it might generate features like moving averages or volatility measures from stock price data.
  • In image recognition, algorithms could generate features by identifying edges, textures, or color histograms in images.
  • ...
• Counter-Example(s):
  • Feature Normalization Algorithm
  • Data Cleaning Algorithm
