MACROS 4.2 Release

DATADVANCE development team is pleased to announce the release of MACROS 4.2, the next stable version of the MACROS library and featured plug-ins.

This release adds several improvements to tensor approximation techniques in GTApprox:

  • The incomplete Tensor Approximation (iTA) technique now supports exact fit, so iTA models can be trained to fit the training data points exactly. Earlier versions of iTA could not be configured to require fitting and thus usually introduced certain smoothing of the model.
  • Better handling of noisy data: in certain cases of noisy training data, the Tensor Approximation (TA) and iTA techniques had an issue with under-smoothing the model. Updated techniques are more stable in these cases; note it requires a specific tuning of the training technique, in particular, no exact fit condition.
