Performance Considerations

To get the best overall performance of the association rules algorithm, whenever possible use the following numeric tables and data types:

  • A SOA numeric table of type int to store features.

  • A homogenous numeric table of type int to store large item sets, support values, and left-hand-side and right-hand-side parts of association rules.

  • A numeric table with the confidence values of the same data type as specified in the algorithmFPType template parameter of the class.

Optimization Notice

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
