In some embodiments, techniques are provided for analyzing time series data to detect anomalies. In some embodiments, a machine learning model is used to process time series data. In some embodiments, a machine learning model is trained on a large amount of previous time series data in an unsupervised manner, allowing for the creation of a high precision model from new data. In some embodiments, the training of the machine learning model alternates between fitting optimization and pruning optimization to allow processing of a large amount of training data including unmarked anomaly records. Because machine learning models are used, anomalies within complex systems, including but not limited to autonomous vehicles such as unmanned aerial vehicles, can be detected. When an anomaly is detected, a command can be sent to a monitored system, such as an autonomous vehicle, to deal with the anomaly.

    在一些实施例中,提供了用于分析时间序列数据以检测异常的技术。在一些实施例中,使用机器学习模型来处理时间序列数据。在一些实施例中,机器学习模型以无监督方式在大量先前时间序列数据上训练,从而允许从新数据中创建高精确模型。在一些实施例中,机器学习模型的训练在拟合优化和修剪优化之间交替,以允许处理包括未标记的异常记录的大量训练数据。因为使用了机器学习模型,能够检测到复杂系统内的异常,包括但不限于,诸如无人飞行器的自主载具。当检测到异常时,能够向被监视系统(如自主载具)发送命令以应对异常。
