Thomas Neidhart commented on MATH-485:
--------------------------------------
Thanks for the comments!
@1 & 2: I do not know about a general decision if algo classes should be
serializable, but I thought it makes sense in this case. The serialization
method was derived from SimplexTableau and the corresponding description in
MathUtils. As the different matrix object can also be set from external, they
may not all be Array2DRowRealMatrix, but I do not know if this makes a
difference for the serialization.
@3: ack, the member variables have been adjusted already, but the constructor
has to be cleaned up
@4: the constant voltage example (from the paper of Welch & Bishop) is the
basis for the test case, but I was really unsure which reasonable test criteria
to use for algorithm validation. The very naive approach I currently use is to
basically test if the estimated state has less diff to the real value than the
artificially imposed measurement/process noise and whether the error covariance
converges to some value (although this is not complete yet).
