1.2.1 Release

Description

This is an update to an existing sampler providing different but more robust results.

Changed

The QuasiRandomNumberSampler has been updated to use scipy's implementation for Sobol and Halton sequences.

Benefits include:

• Continue the sequence from a certain point with the sequence_offset option.
• A scramble option for better randomization
• The directional numbers for generating a Sobol sequence are updated to allow for higher dimensions. Joe and Kuo 2008 This gives different but still valid results compared to the previous version.

1.2.0 Release

Description

Added

• BestCandidateSampler: A new option in trata.adaptive_sampler that chooses new samples that add most to diversity of existing samples.
• All adaptive samples can be passed a random seed for reproducability.
• The sampling documentation notebook has been updated to include adaptive_sampler examples.
• The ProbabilityDensityFunctionSampler will automatically scale values based on ranges passed with the "box" parameter.

Changed

• Adaptive samplers use the same variable names as the rest of the modules. Only "values" for the inputs/X, and "output" for response/Y.

Bug fixes

• Updated some indexing and variable assignment methods to be compatible with numpy > 2.0
• One-at-a-time sampler has input validation and avoids duplicating default values.
• Other fixes and updates to the testing suite

Release 1.1.1

1.1.1 Release

Description

This release includes a minor bug fix.

Bug fixes

• In the sampler module, checking for empty lists was fixed.

Release 1.1.0

1.1.0 Release

Description

This release introduces a new kosh_sampler module

New in this release

• The kosh_sampler module wraps the adaptive sampling functions in a Kosh operator. Users with existing Kosh datasets can easily find the next best set of samples based on their model's error or sensitivity.
• A Sobol index sampler has been added to the sampler module. It creates samples to be used in
  IBIS's Sobol indices function in the sensitivity module.
