-This repository contains the source code for our Foundation model paper titled "Finding Foundation Models for Time Series Classification with a PreText Task". In this paper, we pre-train a deep learning model on a pretext task on multiple datasets from the same domain. This is followed by fine tuning this model on each dataset independently for their own classification task. Here is a summary figure of the approach:
