论文摘要
深度学习是一种潜在的破坏性工具,可以解决整个科学的长期研究问题。尽管在跨学科中取得了成功,但深度学习过度使用的最新趋势与许多机器学习从业人员有关。最近,地震学家还证明了深度学习算法在检测低幅度地震方面的功效。在这里,我们重新审视地震事件检测的问题,但使用具有特征提取的逻辑回归模型。我们从跨学科时间序列分析方法收集的巨大数据库中选择了良好的歧视功能。使用仅具有五个可训练参数的简单学习模型,我们检测到目录中不存在的Groningen气场的几种低稳定性引起的地震。我们注意到,更简单的模型的额外优点是,所选功能增加了我们对数据集中存在的噪声和事件类别的理解。由于更简单的模型易于维护,调试,理解和训练,因此我们强调说,使用深度学习而无需仔细权衡简单的替代方案,这可能是一种危险的追求。
Deep learning is fast emerging as a potential disruptive tool to tackle longstanding research problems across the sciences. Notwithstanding its success across disciplines, the recent trend of the overuse of deep learning is concerning to many machine learning practitioners. Recently, seismologists have also demonstrated the efficacy of deep learning algorithms in detecting low magnitude earthquakes. Here, we revisit the problem of seismic event detection but using a logistic regression model with feature extraction. We select well-discriminating features from a huge database of time-series operations collected from interdisciplinary time-series analysis methods. Using a simple learning model with only five trainable parameters, we detect several low-magnitude induced earthquakes from the Groningen gas field that are not present in the catalog. We note that the added advantage of simpler models is that the selected features add to our understanding of the noise and event classes present in the dataset. Since simpler models are easy to maintain, debug, understand, and train, through this study we underscore that it might be a dangerous pursuit to use deep learning without carefully weighing simpler alternatives.
