Classification

Classification refers to the systematic arrangement of entities into categories or groups based on Shared characteristics or criteria. This process is fundamental in various fields such as biology, information science, and social sciences, allowing for organization, analysis, and understanding of complex data.

Examples:

• Biological Classification: Living organisms are classified into kingdoms, phyla, classes, orders, families, genera, and species. For example, the domestic cat is classified as follows:
  • Kingdom: Animalia
  • Phylum: Chordata
  • Class: Mammalia
  • Order: Carnivora
  • Family: Felidae
  • Genus: Felis
  • Species: Felis catus
• Library Classification: Books in a library are classified using systems like the Dewey Decimal System, which organizes books by subject. For instance, a book on computer programming may fall under the number 005.13.
• Machine Learning: In supervised learning, classification algorithms are used to categorize data into predefined classes. For example, an email can be classified as ‘spam’ or ‘not spam’ based on its content.

Cases:

• Medical Diagnosis: Patients may be classified into categories based on symptoms and test results to assist in diagnosis and treatment.
• Consumer Behavior: Businesses classify consumers into segments based on Demographics, purchasing behavior, and preferences to tailor Marketing strategies.
