Meta Learning with exact information estimation

This project addresses the issue of overfitting in meta-learning by introducing an information-theoretic meta-regularizer, promoting the utilization of task-specific data for better generalization. Instead of relying on mutually-exclusive meta-training tasks, it directly maximizes mutual information using MINE, a scalable and trainable estimator, enhancing meta-learning algorithms’ robustness to new tasks. The study’s experimental evaluation showcases the effectiveness of this approach on non-mutually-exclusive tasks.
