Abstract: In some embodiments, a method receives a first instance of data for anomaly detection. The first instance of data includes values from multiple variables. The first instance of data is stored in a queue. The method weights instances of data in the queue based on data changing over time and projects the instances of the data in the queue into a space. A point in the space represents a correlation of the values for the multiple variables for a respective instance of data. A boundary is generated based on the points in the space.

Abstract: An electronic device and a memristor-based logic gate circuit thereof. In the present application, a control end of a controllable switch is connected to a negative end of an output memristor in a MAGIC-based AND logic gate, and whether a second memristor is powered on is controlled by the controllable switch. Thus, when resistance value states of two input memristors in the AND logic gate are different, the controllable switch will conduct and power on the second memristor, and the second memristor will present a low-resistance state at this time. When the resistance value states of the two input memristors are the same, the controllable switch will not conduct and the second memristor will then remain the state unchanged, i.e., presents a high-resistance state. An exclusive OR logic gate is formed by combining the two input memristors and the second memristor.
