Abstract: An approach to time-series data point anomaly detection is presented. Data point anomalies in time-series data can cause a cascade of incorrect predictions in a time-series data prediction model. Presented herein is an approach to decompose a time-series training data set into elementary components, such as seasonal, trend and residual. The approach determines one or more confidence intervals for elementary components of data points including level shift, variance, and outlier. From these confidence intervals, new data points are analyzed and identified as anomaly data points. The approach also prevents anomaly data points from being incorporated into a time series data prediction model, reducing prediction error in the prediction model.

The wireless circuitry may detect a range between the device and an external object based on the transmitted signals and the reflected signals.
