摘要:

随着新兴技术和所有相关设备的出现,预计在未来几年内将创建大量数据,事实上,多达90%的当前数据是在过去几年中创建的,这一趋势将在可预见的未来继续下去。可持续计算(Sustainable Computing)研究计算机工程师/科学家设计计算机和相关子系统的过程,这些过程有效且对环境的影响最小。然而,目前的智能机器学习系统是性能驱动的,重点是基于从训练样本中学习到的已知属性的预测/分类准确性。例如,大多数基于机器学习的非参数模型都需要很高的计算成本才能找到全局最优值。对于大型数据集中的学习任务,网络中隐藏节点的数量将因此显著增加,这最终导致计算复杂性呈指数级上升。因此,本文回顾了大规模数据密集型领域的理论和实验数据建模文献,涉及:(1)模型效率,包括学习中的计算要求,以及数据密集型领域的结构和设计,并介绍了(2)具有最少内存需求和处理的新算法方法,以最大限度地减少计算成本,同时保持/提高其预测/分类精度和稳定性。

英文摘要:

With the emerging technologies and all associated devices, it is predicted that massive amount of data will be created in the next few years, in fact, as much as 90% of current data were created in the last couple of years,a trend that will continue for the foreseeable future. Sustainable computing studies the process by which computer engineer/scientist designs computers and associated subsystems efficiently and effectively with minimal impact on the environment. However, current intelligent machine-learning systems are performance driven, the focus is on the predictive/classification accuracy, based on known properties learned from the training samples. For instance, most machine-learning-based nonparametric models are known to require high computational cost in order to find the global optima. With the learning task in a large dataset, the number of hidden nodes within the network will therefore increase significantly, which eventually leads to an exponential rise in computational complexity. This paper thus reviews the theoretical and experimental data-modeling literature, in large-scale data-intensive fields, relating to: (1) model efficiency, including computational requirements in learning, and data-intensive areas structure and design, and introduces (2) new algorithmic approaches with the least memory requirements and processing to minimize computational cost, while maintaining/improving its predictive/classification accuracy and stability.
