    • Embodiments of the present invention provide an approach for adapting an information extraction middleware for a clustered computing environment (e.g., a cloud environment) by creating and managing a set of statistical models generated from performance statistics of operating devices within the clustered computing environment. This approach takes into account the required accuracy in modeling, including computation cost of modeling, to pick the best modeling solution at a given point in time. When higher accuracy is desired (e.g., nearing workload saturation), the approach adapts to use an appropriate modeling algorithm. Adapting statistical models to the data characteristics ensures optimal accuracy with minimal computation time and resources for modeling. This approach provides intelligent selective refinement of models using accuracy-based and operating probability-based triggers to optimize the clustered computing environment, i.e., maximize accuracy and minimize computation time.
    • 本发明的实施例提供了一种用于通过创建和管理从群集计算环境内的操作设备的性能统计生成的一组统计模型来适配用于群集计算环境(例如,云环境)的信息提取中间件的方法。 这种方法考虑了所需的建模精度,包括建模的计算成本,以便在给定时间点选择最佳建模解决方案。 当需要更高的精度(例如,接近工作负载饱和)时,该方法适应于使用适当的建模算法。 将统计模型适应数据特征确保最佳精度,最小的计算时间和建模资源。 该方法提供使用基于精度和基于概率的触发器来优化群集计算环境(即,最大化精度和最小化计算时间)的模型的智能选择性细化。
