Pattern Recognition

(Information Science Guru) Pattern Recognition

• Recognizing patterns based on input and producing output

  • Humans do it unconsciously (probably most artificial intelligence systems do too)
  • In a sense, pattern recognition can be said to encompass all aspects of human life

• Determining which class a given input belongs to from a predefined set of classes

• Is it correct to say that class classification is synonymous with pattern recognition?

  • Is pattern recognition considered an application field of machine learning?

• (From Professor Uchida’s slides)

• The difficulty (=interest) of pattern recognition

  • Involves aspects of human cognition and philosophy
  • What does “similarity” mean?
  • What should we focus on?
  • Class indeterminacy (similar to the Symbol Placement Problem)
  • Curse of Dimensionality

• In the case of images#image processing#digital image processing
  • Two approaches

    • Class classification using distance calculation of extracted image features

    • Class classification using machine learning on extracted image features
