Inner loop optimization

Definition

Inner loop optimization refers to a technique used in meta-learning where a model is trained through rapid iterations on a specific task, refining its parameters based on immediate feedback. This process allows the model to quickly adapt and improve its performance on similar tasks by effectively minimizing the loss function in the context of few-shot learning. It emphasizes the importance of efficient learning strategies that enable models to perform better with limited data by optimizing how they learn from each iteration.
