Batch Processing

AdaBoost classifier follows the general workflow described in Usage Model: Training and Prediction.

Training

For a description of the input and output, refer to Usage Model: Training and Prediction.
At the training stage, an AdaBoost classifier has the following parameters:
Parameter
Default Value
Description
algorithmFPType
float
The floating-point type that the algorithm uses for intermediate computations. Can be
float
or
double
.
method
defaultDense
The computation method used by the AdaBoost classifier. The only training method supported so far is the Y. Freund's method.
weakLearnerTraining
Pointer to an object of the stump training class
Pointer to the training algorithm of the weak learner. By default, a stump weak learner is used.
weakLearnerPrediction
Pointer to an object of the stump prediction class
Pointer to the prediction algorithm of the weak learner. By default, a stump weak learner is used.
accuracyThreshold
0.01
AdaBoost training accuracy.
maxIterations
100
The maximal number of iterations for the algorithm.

Prediction

For a description of the input and output, refer to Usage Model: Training and Prediction.
At the prediction stage, an AdaBoost classifier has the following parameters:
Parameter
Default Value
Description
algorithmFPType
float
The floating-point type that the algorithm uses for intermediate computations. Can be
float
or
double
.
method
defaultDense
Performance-oriented computation method, the only method supported by the AdaBoost classifier at the prediction stage.
weakLearnerPrediction
Pointer to an object of the stump prediction class
Pointer to the prediction algorithm of the weak learner. By default, a stump weak learner is used.

Product and Performance Information

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.
