Record 2 1996-06-11

English

Subject field(s)
  • Artificial Intelligence
  • Applications of Automation
DEF

A system of mathematical analysis that enables the computer to use fewer numbers when storing template details, so facilitating significant memory savings.

DEF

Prediction coding in which the predicted signal samples are linear combinations of the previous samples. (ISO/CEI, 2382-29, 1996).

French

Domaine(s)
  • Intelligence artificielle
  • Automatisation et applications
