In LeastSquaresProblem.Evaluation removed the getValue() method.
...
- The residuals are the really the values of the objective function
that is being minimized.
- Forcing the value to be a real vector and the residual computed
through subtraction is an unnecessary constraint. For example
Rotation.distance() will compute a better residual than
subtracting the quaternion elements of two rotations.
- Method was not used by any optimizer.

Make QR in GaussNewton faster and more accurate
...
Re-factored the code in GaussNewtonOptimizer so that the decomposition
algorithm sees the Jacobian and residuals instead of the normal
equation. This lets the QR algorithm operate directly on the Jacobian
matrix, which is faster and less sensitive to numerical errors. As a
result, one test case that threw a singular matrix exception now passes
with the QR decomposition.
The refactoring also include a speed improvement when computing the
normal matrix for the LU decomposition. Since the normal matrix is
symmetric only half of is computed, which results in a factor of 2 speed
up in computing the normal matrix for problems with many more
measurements than states.

Use Real{Vector,Matrix} in LeastSquares interfaces
...
Covered all of the interfaces in the leastsquares package to use RealVector and
RealMatrix instead of double[] and double[][]. This reduced some duplicated code.
For example Evaluation.computeResiduals() was a complete duplication of
RealVector.subtract(). It also presents a consistent interface and allows data
encapsulation.
Lastly, this change enables [math] to "eat our own dog food." It enables the
linear package to be used in the implementation of the optimization algorithms.

Use Evaluation instead of PointVectorValuePair

Use Evaluation instead of PointVectorValuePair in the ConvergenceChecker. This
gives the checkers access to more information, such as the rms and covariances.
The change also simplified the optimizer implementations since they no longer
have to keep track of the current function value.
A method was added to LeastSquaresFactory to convert between the two types of
checkers and a method added to LeastSquaresBuilder so that it can accept either
type. I would have prefered to do this through method overloading, but
overloading doesn't play well with generics.

Implicit Weights
...
The weights are no longer implicit in LeastSquaresProblem.Evaluation. They are
already included in the computed residuals and Jacobian.
GN and LM multiplied the residuals by the weights immediately, so that was easy
to remove.
Created an AbstractEvaluation class which handles the derived quantitied (cost,
rms, covariance,...) and two implementations. UnweightedEvaluation uses the
straight forward formulas. DenseWeightedEvaluation delegates to an Evaluation
and multiples the residuals and Jacobian by the square root of the weight matrix
before returning them. Allowed me to remove the reference to the full weight
matrix.

Separate least squares algorithm from problem.

The least squares package now has two main interfaces LeastSquaresOptimizer and
LeastSquaresProblem, where the optimizer can be applied to the problem.
In this commit all of the test cases pass with one change (annotated) to
LevenbergMarquardt.testControlParameters(). The tests for Gauss Newton were
expanded to cover using the QR decomposition, which revealed a QR default
tolerance discrepancy.
A factory and a mutable builder were create for LeastSquaresProblem.

Added a getEnclosingCap method for spherical polygons.
...
In simple cases (small polygon, one piece only, no holes), the enclosing
cap will be the smallest one, but this is not guaranteed in the general
case.
The enclosing cap can be used to speed up inside/outside points when the
region is small with respect to the sphere as with only one check of an
angular separation, most points of the sphere can be safely identified
as outside. The more time-consuming checks involving the full boundary
are therefore done only for a small portion of the sphere.

Fixed sphere generation in degenerated cases.
...
In almost coplanar / almost colinear cases, sphere generation could
diverge in such a way the support points did not belong to the sphere
anymore! This new implementation uses exact arithmetic for the
computation. It is much slower, but since very few balls should be
generated during the Welzl algorithm execution, this is probably
acceptable.

BSP tree now provide an API to compute a global signed distance.
...
The distance is defined from a test point to the region. It is positive
if the point is outside of the region, negative if the point is inside,
and zero when the point is at the boundary. The distance is continuous
everywhere, so it can be used with a root solver to identify accurately
boundary crossings. This API is available for all BSP trees, in
Euclidean and spherical geometries, and in all dimensions.

Don't advertise an assumption we may remove soon.
...
We will probably extend the circle class to also represent small circles
on the 2-sphere, not only great circles. This would introduce an
aperture angle that could be different from \pi/2. In this case, the
part of a circle inside another circle may exist or not (small circles
can be disjoint), and may have a length either shorter or longer than
\pi.
This change is not done yet, but could happen any time soon, even before
3.3 is out.

Implementation of Kohonen's Self-Organizing Feature Map (SOFM).
New package "o.a.c.m.ml.neuralnet" contains base functionality for implementing
different map types, i.e. methods that project a high-dimensional space onto one
with a low dimension (typically 1D or 2D).
The SOFM-specific code is in "o.a.c.m.ml.neuralnet.sofm".
