This paper proposes a new method for explaining time series classification models. The approach, called Time-CF, is model-agnostic, meaning it can be used with any existing time series classifier. It uses two techniques: shapelets and TimeGAN, to generate counterfactual instances that provide insights into the decision-making process of the model. The authors evaluate their method on several real-world datasets from the UCR Time Series Archive and show that it outperforms state-of-the-art methods in terms of four explainability metrics.

This paper is about making machines understandable. It’s like trying to figure out why a machine made a certain decision, even if you didn’t program it yourself. The researchers developed a new way to do this for time series data, which is used for forecasting and analyzing patterns in things like stock prices or weather. They tested their method on several datasets and found that it works better than other methods at explaining what the machine did.
