Transfer learning for time series classification using synthetic data generation
This work addresses the problem of data scarcity in time series classification for researchers, though it is incremental as it builds on existing transfer learning methods.
The paper tackles time series classification by generating a large synthetic dataset and using regression tasks for transfer learning, achieving better results than using existing classification tasks from the UCR archive.
In this paper, we propose an innovative Transfer learning for Time series classification method. Instead of using an existing dataset from the UCR archive as the source dataset, we generated a 15,000,000 synthetic univariate time series dataset that was created using our unique synthetic time series generator algorithm which can generate data with diverse patterns and angles and different sequence lengths. Furthermore, instead of using classification tasks provided by the UCR archive as the source task as previous studies did,we used our own 55 regression tasks as the source tasks, which produced better results than selecting classification tasks from the UCR archive
