- Apache Commons Math 3.4 RELEASE NOTES
+ Apache Commons Math 3.4.1 RELEASE NOTES
-The Apache Commons Math team is pleased to announce the release of commons-math3-3.4
+The Apache Commons Math team is pleased to announce the release of commons-math3-3.4.1
The Apache Commons Math project is a library of lightweight, self-contained mathematics
and statistics components addressing the most common practical problems not immediately
available in the Java programming language or commons-lang.
-This is a minor release: It combines bug fixes and new features.
-Changes to existing features were made in a backwards-compatible
-way such as to allow drop-in replacement of the v3.3 JAR file.
-
-Most notable among the new features are:
-new distributions (Gumbel, Laplace, Logistic, Nakagami), and
-improvements on percentiles algorithms (better handling for NaNs
-in the regular algorithm, plus a new storeless implementation).
-Bicubic and tricubic interpolators have been fixed and new
-implementations added. There have been numerous bug fixes and
-several improvements on performances or robustness. See below
-for a full list.
-
-The minimum version of the Java platform required to compile and use
-Apache Commons Math is Java 5.
-
-Users are encouraged to upgrade to this version as this release not
-only includes bug fixes but also deprecates numerous classes and
-methods that will be deleted from the next major release (4.0).
-
-
-Caveat:
- 1. The implementation of the BOBYQA optimization algorithm is in alpha
- state (cf. MATH-621): Many code paths are untested, and we are looking
- for volunteers to improve the code readability, robustness and performance
- and to extend the unit tests suite.
- 2. A few methods in the FastMath class are in fact slower that their
- counterpart in either Math or StrictMath (cf. MATH-740 and MATH-901).
+This is a maintenance release: It fixes issue MATH-1188.
Changes in this version include:
-New features:
-o MATH-1066: Added Bessel functions of the first kind, based on NetLib implementation. Thanks to Brian Wignall.
-o MATH-1180: Method to create a sequence of integers (in "o.a.c.m.util.MathArrays").
-o MATH-1172: New class "SimpleCurveFitter": Boiler-plate code to allow fitting of
- a user-defined parametric function.
-o MATH-1173: New classes "TricubicInterpolatingFunction" and "TricubicInterpolator" to
- replace "TricubicSplineInterpolatingFunction" and "TricubicSplineInterpolator".
-o MATH-1166: New classes "BicubicInterpolatingFunction" and "BicubicInterpolator" to
- replace "BicubicSplineInterpolatingFunction" and "BicubicSplineInterpolator".
-o Boundary attributes in regions now provides the BSP tree nodes that
- were used to split the sub-hyperplane forming the boundary part of the facet.
-o MATH-1144: Interface to allow parameter validation in "o.a.c.m.fitting.leastsquares":
- the point computed by by the optimizer can be modified before evaluation.
-o MATH-1154: Changed classes in the inference package that instantiate distributions to
- pass null RandomGenerators to avoid initialization overhead for the default
- generator.
-o MATH-1156: Added all Java 8 StrictMath methods to FastMath, so FastMath remains compatible
- with newer Java versions.
-o MATH-1139: Added Gumbel, Laplace, Logistic and Nakagami distributions. Thanks to Alexey Volkov.
-o MATH-1120: Added several different estimation types and NaN handling strategies for Percentile. Thanks to Venkatesha Murthy.
-o MATH-418: Added implementation of PSquare algorithm to estimate percentiles without
- storing data in memory (i.e. as StorelessUnivariateStatistic). Thanks to Venkatesha Murthy.
Fixed Bugs:
-o MATH-1142: Improve performance of kalman gain calculation in "KalmanFilter" by
- directly solving a linear system rather than computing the matrix
- inverse. Thanks to Arne Schwarz.
-o MATH-1181: Fixed integer overflow in KolmogorovSmirnovTest causing 2-sample test
- to use exact method when the product of the sample sizes exceeds
- Integer.MAX_VALUE, resulting in effectively hung execution.
-o MATH-1178: Fixed example in userguide ("stat" section). Thanks to Dmitriy.
-o MATH-1175: Fixed inverse cumulative probability of 0 in "LaplaceDistribution". Thanks to Karsten Loesing.
-o MATH-1174: Fixed a problem with too thin polygons considered to have infinite size.
-o MATH-1162: Fixed a problem with vanishing cut sub-hyperplanes during BSP tree merging.
-o MATH-1167: "o.a.c.m.stat.regression.OLSMultipleLinearRegression": Use threshold
- when performing "QRDecomposition". Thanks to Neil Ireson.
-o MATH-1165: "FuzzyKMeansClusterer" has thrown an exception in case one of the data
- points was equal to a cluster center. Thanks to Pashutan Modaresi.
-o MATH-1160: Provide access to state derivatives in ContinuousOutputModel.
-o MATH-1138: Fixed bicubic spline interpolator, using Akima splines. Thanks to Hank Grabowski.
-o MATH-1147: Added statistics missing from toString method in SummaryStatistics.
-o MATH-1152: Improved performance of "EnumeratedDistribution#sample()" by caching
- the cumulative probabilities and using binary rather than a linear search. Thanks to Andras Sereny.
-o MATH-1148: "MonotoneChain" did not take the tolerance factor into account when
- sorting the input points. In case of collinear points this could result
- in a "ConvergenceException" when computing the hull. Thanks to Guillaume Marceau.
-o MATH-1151: Interface "ValueAndJacobianFunction" is a precondition for lazy
- evaluation (in "o.a.c.m.fitting.leastsquares").
-o MATH-1145: Fix potential integer overflows in "MannWhitneyUTest" when providing
- large sample arrays. Thanks to Anders Conbere.
-o MATH-1149: Fixed potential null pointer dereferencing in constructor of
- "DummyStepInterpolator(DummyStepInterpolator)". Thanks to M Kim.
-o MATH-1136: Fixed BinomialDistribution to deal with degenerate cases correctly. Thanks to Aleksei Dievskii.
-o MATH-1135: "MonotoneChain" failed to generate a convex hull if only a minimal hull
- shall be created (includeCollinearPoints=false) and collinear hull points
- were present in the input. Thanks to Guillaume Marceau.
-o MATH-1131: Improve performance of "KolmogorovSmirnovTest#kolmogorovSmirnovTest(...)" for
- large samples. Also changed implementation for large n to use Pelz-Good
- approximation. Thanks to Schalk W. Cronjé.
-o MATH-1134: "BicubicSplineInterpolatingFunction": all fields made final and initialized in
- the constructor. Added flag to request initialization, or not, of the internal
- data needed for partial derivatives.
-o MATH-984: Constrained EmpiricalDistribution sample/getNextValue methods to return
- values within the range of the data; correctly linked RandomGenerator to
- superclass so that RealDistribution reseedRandomGenerator method works.
-o MATH-1129: "Percentile": wrong sorting in the presence of NaN.
-o MATH-1127: Fixed overflow in Precision.equals with ulps (both double and float versions).
-o MATH-1125: Performance improvements for Student's t-distribution. Thanks to Ajo Fod.
-o MATH-1123: Fixed NullPointerException when chopping-off a sub-hyperplane
- that is exactly at a region boundary. Thanks to Aurélien Labrosse.
-o MATH-1121: "BrentOptimizer": increment base class iteration counter. Thanks to Ajo Fod.
+o MATH-1188: Fixed non-Java1.5 code in BesselJ.
-Changes:
-o Spurious vertices in the middle of otherwise straight edges are now
- filtered out when rebuilding polygons boundaries from BSP trees.
-o MATH-1128: Added lazy evaluation to "LeastSquaresFactory" (in "o.a.c.m.fitting.leastsquares")
- to avoid evaluating the model when the optimization algorithm does not actually
- require it.
