Co-Processor for evolutionary full decision tree induction

In this paper a co-processor for the hardware aided decision tree induction using evolutionary approach (EFTIP) is proposed. EFTIP is used for hardware acceleration of the fitness evaluation task since this task is proven in the paper to be the execution time bottleneck. The EFTIP co-processor can significantly improve the execution time of a novel algorithm for the full decision tree induction using evolutionary approach (EFTI) when used to accelerate the fitness evaluation task. The comparison of the HW/SW EFTI implementation with the pure software implementation suggests that the proposed HW/SW architecture offers substantial DT induction time speedups for the selected benchmark datasets from the standard UCI machine learning repository database.
