New Features and Changes
This release includes numerous performance improvements in DIM execution across optimization and simulation scenarios.
- For Simulation Scenarios, the logic has been streamlined to calculate over one treatment only (aka the valid/assigned treatment), and not over all treatments. This will improve run times, especially for scenarios with many treatments.
- Implemented smarter batch sizing during DIM execution, to better control the amount of memory used. Now the expected (peak) memory usage is estimated, and DIM batches are sized to keep the (peak) memory within the configured limit (default 12GB).
- Enabled parallel execution (for 2 threads), during DIM batch execution. In large sample projects, the run times were ~30% faster.
Note: this release of Decision Optimizer requires a minimum version of Xpress 9.4 and Xpress Insight 5.10.
Additionally, the Action Effect Modeling 2.2 releaseincludes the following.
New Features and Changes
- Categorical variables are supported. User can define the mapping from category names to their numerical orders, and customize the bin label names.
- Summary statistics for the unprocessed dataset report standard deviation, weighted sum, count of empty/non-empty records, and count of zero records.
- Additional Weight of Evidence formula based on counts of good and bad records is now supported in case the target is binary.
Defect Remediation
- Fixed record count when numerical records were provided with a string (e.g., “1 ”).
- Custom bin breakpoints are now added with “<” by default.
Note: This release of Action Effect Modeling requires a minimum version of Xpress 9.4 and Xpress Insight 5.10.
