The ability to detect and diagnose engine faults, failures, or even shutdowns in flight has clear implications for aviation safety. One objective of the work presented here is to investigate mature data-driven techniques for the detection and diagnosis of real-time engine shutdowns in flight.

If you are developing an anomaly detection system, there is no way to make use of labeled data to improve your system. When choosing features for an anomaly detection system, it is a good idea to look for features that take on unusually large or small values for (mainly the) anomalous examples.
anomaly detection is the time-based inductive learning ma-chine (TIM) of Teng et al. . Their algorithm constructs a set of rules based upon usage patterns. An anomaly is signalled when the premise of a rule occurs but the conclusion does not follow. Singliar and Hauskrecht use a support vector machine to detect anomalies in road trafﬁc .
More formally, we consider an anomaly detection strategy given by b(Xp)= S where b is a black-box detector, Xpis a dataset with p features, and S is the space of scores generated by the detector. The goal is to find an explanatione ∈ϵfor each x ∈Xp, where ϵrepre- sents the domain of interpretable explanations.
Anomaly detection in streaming datasets is the ability to handle high volumes of abnormal data patterns in the distribution of data. In this survey, we have discussed different problem compositions that are relevant in varied streaming data applications domains within and outside of anomaly detection.
Your detection result should be in the same format as described in the handout of project 2. Specifically, there should be only 2 columns separated by the comma: record ID - The unique identifier for each connection record. is_anomaly?_ This binary field indicates your detection result: 0 denotes the transmission is normal, 1 indicates anomalous.
