Researchers have introduced a new technique called Ground-Truth Neighborhood Regularization (GTN-R) to improve the performance of time series foundation models (TSFMs) when using reinforcement learning (RL) for post-training. They identified a problem called "suboptimal collapse," where RL training can shift model outputs away from the correct values, limiting accuracy. GTN-R addresses this by using the ground truth as a reference to guide the model towards accurate predictions, thereby increasing the likelihood of sampling high-quality data and enhancing overall performance. This method can be integrated with various RL approaches for TSFMs and has shown effectiveness in experiments. AI
