Transferable Reinforcement Learning via Generalized Occupancy Models: A Novel Approach for Adaptive Decision Making

Q: How can GOMs be further improved to handle non-linear reward functions effectively

GOMs can be further improved to handle non-linear reward functions effectively by incorporating more expressive feature learning methods for cumulants. Instead of relying on linear relationships between rewards and cumulants, GOMs can leverage advanced techniques such as deep neural networks or kernel methods to capture the non-linear mappings between rewards and features. By using these more sophisticated models, GOMs can better represent complex reward structures and improve their adaptability to a wider range of tasks with non-linear reward functions.

Q: What are the potential limitations of using linear cumulants in GOMs for modeling future outcomes

The potential limitations of using linear cumulants in GOMs for modeling future outcomes lie in the assumption that rewards are perfectly represented as linear combinations of features. In reality, many environments have non-linear relationships between state features and rewards, making it challenging for linear cumulants to accurately capture the dynamics of the environment. This limitation may lead to suboptimal policies when dealing with tasks that exhibit significant non-linearity in their reward functions.

Q: How can the dataset skewness impact the optimality of policies learned by GOMs, and how can this issue be addressed

Dataset skewness can impact the optimality of policies learned by GOMs by introducing biases towards certain trajectories or outcomes present in the dataset. If the dataset is skewed towards specific behaviors or states, GOMs may prioritize those trajectories over others during policy optimization, leading to suboptimal performance on unseen tasks. To address this issue, one approach is to employ data augmentation techniques that balance out the distribution of trajectories in the dataset. By augmenting data from underrepresented areas of the state space or less frequent behaviors, GOMs can learn more robust policies that generalize well across various scenarios without being biased towards specific trajectories from skewed datasets.
