type TrainingVector = Vector DoubleSource
A vector used for deriving the parameters of a Dirichlet density or mixture.
type TrainingVectors = Vector TrainingVectorSource
A vector of training vectors. This is the only vector that is not unboxed (for obvious reasons).
Usually denoted by lowercase greek letter eta (η), size of each step in the gradient. Should be greater than zero and much less than one.
Predicate specifying when the training should be over.
Pred | |
|
Reason why the derivation was over.
Delta | The difference between applications of the cost function dropped below the minimum delta. In other words, it coverged. |
MaxIter | The maximum number of iterations was reached while the delta was still greater than the minimum delta. |
CG Result | CG_DESCENT returned this result, which brought the derivation process to a halt. |
Result of a deriviation.
