Individuals from Pittsburgh rule-based classifiers represent a complete solution
to the classification problem and each individual is a variable-length set
of rules. Therefore, these systems usually demand a high level of computational
resources and run-time, which increases as the complexity and the size
of the data sets. It is known that this computational cost is mainly due to
the recurring evaluation process of the rules and the individuals as rule sets.
In this paper we propose a parallel evaluation model of rules and rule sets on
GPUs based on the NVIDIA CUDA programming model which significantly
allows reducing the run-time and speeding up the algorithm. The results
obtained from the experimental study support the great efficiency and high
performance of the GPU model, which is scalable to multiple GPU devices.
The GPU model achieves a rule interpreter performance of up to 64 billion
operations per second and the evaluation of the individuals is speeded up of
up to 3.461脳 when compared to the CPU model. This provides a significant
advantage of the GPU model, especially addressing large and complex
problems within reasonable time, where the CPU run-time is not acceptabl
