摘要:

我们提出了一种用于自适应采样的自适应调度方法,作为在词性标注器构建中进行机器学习的一种新方式。其目标是在大型数据集上加速训练,同时相对于最优配置而言,不造成显著的性能损失。与先前使用随机、固定或规则递增的实例间间隔的方法不同,我们的方法结合函数模型,从几何角度分析学习曲线的形状,以随时增加或减少间隔。该算法在我们的工作假设下被证明是形式正确的。即,给定一个案例,下一个案例是确保从前一个案例获得净学习能力提升的最近案例,并且可以调节该条件的满足程度。我们还通过更加关注训练数据中那些性能暂时膨胀的区域来提高采样的鲁棒性,从而防止学习过早停止。该提案基于其识别模型收敛的可靠性进行了评估,证实了我们的预期。虽然测试时使用了具体的停止条件,但用户可以根据自己的特定需求选择任何条件。

英文摘要:

We introduce an adaptive scheduling for adaptive sampling as a novel way of machine learning in the construction of part-of-speech taggers. The goal is to speed up the training on large data sets, without significant loss of performance with regard to an optimal configuration. In contrast to previous methods using a random, fixed or regularly rising spacing between the instances, ours analyzes the shape of the learning curve geometrically in conjunction with a functional model to increase or decrease it at any time. The algorithm proves to be formally correct regarding our working hypotheses. Namely, given a case, the following one is the nearest ensuring a net gain of learning ability from the former, it being possible to modulate the level of requirement for this condition. We also improve the robustness of sampling by paying greater attention to those regions of the training data base subject to a temporary inflation in performance, thus preventing the learning from stopping prematurely. The proposal has been evaluated on the basis of its reliability to identify the convergence of models, corroborating our expectations. While a concrete halting condition is used for testing, users can choose any condition whatsoever to suit their own specific needs.
