In science the challenge is always finding a signal in the noise. Examples include hurricane forecasting and monitoring both intelligence and seismic activity. Our proposal addresses these issues through a broad framework we call generalized feature mining. The framework has two major components: feature mining, and shape-based data mining and analysis. At its core, feature mining detects features for a specific application domain. Each instance involves a specific extended shape description tailored to it. For evolutionary simulations, feature mining also tracks features across multiple temporal scales. Shape-based data mining and analysis learn from the process. The aim is to correlate information from the extended shape descriptors with transient detection to find or refine spatio-temporal rules for the evolution of features. Environmental influences, such as walls, must be built into the rules so they are predictive.To close the loop, the detected features can be displayed as they are found or refined. The evolutionary rules predicted by our framework can lead to new science { not only understanding the underlying phenomena but also leading to computationally simpler models that encapsulate the essentials.

在科学中，挑战始终是在噪音中找到信号。例子包括飓风预报以及情报和地震活动监测。 我们的建议通过一个广泛的框架来解决这些问题，我们称之为广义特征挖掘。该框架有两个主要组成部分：特征挖掘以及基于形状的数据挖掘和分析。特征挖掘的核心是检测特定应用程序域的特征。 每个实例都涉及为其量身定制的特定扩展形状描述。对于进化模拟，特征挖掘还跟踪多个时间尺度的特征。基于形状的数据挖掘和分析从过程中学习。目的是将扩展形状描述符的信息与瞬态检测相关联，以找到或完善特征演化的时空规则。环境影响（例如墙壁）必须内置到规则中，以便它们具有预测性。为了闭合循环，可以在发现或细化检测到的特征时显示它们。我们的框架预测的进化规则可以带来新的科学{不仅可以理解潜在的现象，还可以产生封装了本质的计算更简单的模型。
