Benefits of technology
The invention helps prevent problems with predicting models from becoming unstable during processing. It involves pre-processes that can help reduce this problem by reducing fluctuations caused by factors like changes or noise.
Problems solved by technology
This patent describes techniques for detecting abnormalities in time series data, specifically time series anomalies. However, existing solutions either lack speed or accuracy, making their use challenging in practicality scenarios where timely and precise detection is crucial. Existing methods also suffer from issues like false negatives due to factors like noise and instability caused by the method's response time.

Abstract
A method for operating a real-time time series prediction model includes obtaining a first sequence corresponding to a target time series; obtaining a second sequence corresponding to a peer time series of the target time series; determining whether a predetermined number of time steps have elapsed since a last retraining of the real-time time series prediction model; and if the predetermined number of time steps have elapsed since the last retraining of the time series prediction model, retraining the real-time time series prediction model using a first portion of the first and second sequences; and applying a remaining portion of the first and second sequences to the real-time time series prediction model to predict a next value of the target time series.
