This paper introduces Trend Point Detection, a novel approach to simplifying complex time series data using Markov Decision Process (MDP) and Reinforcement Learning (RL). The proposed method, Dynamic Trend Filtering network (DTF-net), aims to identify essential points in the trend (Dynamic Trend Points or DTPs) that are often missed by traditional trend filtering methods. By interpolating these DTPs, the authors demonstrate improved forecasting performance and the ability to capture abrupt changes in trends. Unlike existing approaches, which uniformly filter out noise, DTF-net preserves critical original subsequences while removing noise as required for other subsequences. The authors compare their method with other trend filtering algorithms, showing that it excels at capturing abrupt changes.

This research paper is about finding patterns in complex data sets over time. Right now, there are problems with the way we filter out unwanted information (noise) from this kind of data. The noise can hide important changes or events in the pattern. To solve this problem, the authors propose a new method called Dynamic Trend Filtering network (DTF-net). It uses special techniques to identify and keep track of the most important points in the pattern. This allows for better forecasting (predicting what will happen next) and capturing sudden changes. The authors compare their method with others and show that it is more effective at finding these important changes.
