> Key: IGNITE-9124
> URL: https://issues.apache.org/jira/browse/IGNITE-9124
> Project: Ignite
> Issue Type: Task
> Components: ml
> Affects Versions: 2.6
> Reporter: Oleg Ignatenko
> Priority: Major
> Fix For: 2.7
>
>
> Doing code coverage analysis discovered a bit of unused code:
> # in package
> [math.exceptions|https://github.com/apache/ignite/tree/master/modules/ml/src/main/java/org/apache/ignite/ml/math/exceptions]
> - classes ConvergenceException / MathIllegalStateException,
> InsufficientDataException, MathArithmeticException,
> MathIllegalNumberException / NumberIsTooSmallException,
> NonPositiveDefiniteMatrixException, NonSymmetricMatrixException,
> NullArgumentException, SingularMatrixException, UnknownProviderException. In
> very early releases of ML these exceptions were used by some linear algebra
> code. This code has been very deeply reworked since but outdated exceptions
> were left hanging unattended, making rather confusing impression of the
> current API.
> # in
> [optimization|https://github.com/apache/ignite/tree/master/modules/ml/src/main/java/org/apache/ignite/ml/optimization]
> - interface Updater and two classes implementing it: BarzilaiBorweinUpdater
> and SimpleUpdater. This code has left hanging after cleanup that was made for
> release 2.5 (IGNITE-8232). Per my discussion with [~dmitrievanthony] (who
> most actively maintains this package) it would be better to remove this code.
> This task is to remove code mentioned above.
