Unit 12: Learning




              In discovery learning, the learner utilizes his own experience and  prior knowledge  to  Notes
               learn the truths that are to be studied.

          12.14 Keywords


          Classification: It is the procedure of allocating, to a specific input, the name of a class to which
          it associates.
          Explanation-based Learning (EBL): An Explanation-based Learning (EBL) system accepts an
          example (i.e. a training example) and illustrates what it learns from the example.
          Induction: The thought of generating a classification program that can develop its own class
          definitions is known as concept learning or induction.

          Learning: Learning is defined as modifications in the system that are adaptive in the sense that
          they facilitate the system to do the similar task or tasks taken from the similar population more
          competently and more successfully the next time.
          Rote Learning: Rote learning is the  fundamental learning  activity  which is  also known  as
          memorization since the knowledge, without any alteration is, just copied into the knowledge
          base.
          Winston’s Learning Program: It is an early structural concept learning program which functions
          in a simple blocks world domain.
