AI总结:

本文提出 OLR-WA 在线线性回归方法,通过用户定义权重融合新旧数据,在一致数据上与批量模型性能相近,并能灵活控制对数据变化的适应速度。

摘要:

机器学习需要大量训练数据才能构建准确的模型。有时数据会随时间陆续到达,这需要大量存储空间,并且需要重新计算模型以纳入新数据。在线学习通过随着数据到来逐步修改模型并随后丢弃数据来解决这些问题。在本研究中,我们提出了一种新的在线线性回归方法。我们的方法将新到达的数据与先前已有的模型相结合,以创建一个新模型。所提出的模型名为 OLR-WA(基于加权平均的在线回归),它使用用户定义的权重,在面对变化的数据时提供灵活性,使结果偏向于旧数据或新数据。我们进行了二维和三维实验,将 OLR-WA 与使用完整数据集的静态模型进行比较。结果表明,对于一致的数据,OLR-WA 和静态批量模型表现相似;对于变化的数据,用户可以设置 OLR-WA 以更快地适应或抵抗变化。

英文摘要:

Machine Learning requires a large amount of training data in order to build accurate models. Sometimes the data arrives over time, requiring significant storage space and recalculating the model to account for the new data. On-line learning addresses these issues by incrementally modifying the model as data is encountered, and then discarding the data. In this study we introduce a new online linear regression approach. Our approach combines newly arriving data with a previously existing model to create a new model. The introduced model, named OLR-WA (OnLine Regression with Weighted Average) uses user-defined weights to provide flexibility in the face of changing data to bias the results in favor of old or new data. We have conducted 2-D and 3-D experiments comparing OLR-WA to a static model using the entire data set. The results show that for consistent data, OLR-WA and the static batch model perform similarly and for varying data, the user can set the OLR-WA to adapt more quickly or to resist change.
