Model Learning

Karten in diesem Stapel (5)

  1. 1Describe model learning in two wordsSelf-organising, unsupervised
  2. 2—E - learning rate
    i - index of particular input unit
    If E = 0 nothing would happen    E - learning rate i - index of particular input unit If E = 0 nothing would happen
  3. 3What is SPCA and its problemsSequential PCA - order units strongest to weakest
    Heterarchy world not hierarchy- bunch of smaller categories not one large one
  4. 4What is CPCAConditional PCA
    Used to specify conditions under which a given unit should perform its PCA function
  5. 5—CPCA
    E - learning rate
    xi - input unit
    wij - weights
    y = 0 nothing happens
    y = 1 (big) -
    xi<0.5 weight goes down
    xi>0.5 weight goes up    CPCA E - learning rate xi - input unit wij - weights y = 0 nothing happens y = 1 (big) - xi&lt;0.5 weight goes down xi&gt;0.5 weight goes up
