  13. I would like to try to apply an ANN to the evaluation of student language
  14. tests.  The system would have a net for each question, and the question
  15. i/o would be structured as follows:
  16.                       +----+
  17.         Correct Answer ----[string]-->|C   |
  18.     Student's Answer --[string]-->|    O  |
  19.                       |  M |
  20.                       |   P|
  21.                       +----+
  22.     ----                 |
  23.    +---- \  <--------------------------[int] Current Score
  24.    |     /                       |
  25.    |    ----                 V
  26.    V                     +------+
  27. History of Scores --[array of int]-->| ANN  |--[int]--> Confidence
  28.                      +------+
  29.  
  30. The ``Current Score'' represents the correlation between the student's
  31. answer and the correct answer, and the ``Confidence'' value represents the
  32. state of the learning curve.  I would like to use this confidence value to
  33. modulate the test dynamically, feeding back in such a way that confidence
  34. increases at the fastest rate possible.
  35.  
  36. That is, I want to use the ANN to control a learning curve, the student's
  37. learning curve.
  38.  
  39. Has anybody seen such an application before?
