### Key points - Instead of just focusing on supervised learning, a self-critique and adapt network provides a unsupervised learning approach in improving the overall generalization. It does this via transductive learning by learning a label-free loss function from the validation set to improve the base model. - The SCA framework helps a learning algorithm be more robust by learning more relevant features and improve during the training phase. ### Ideas 1. Combine deep learning models with SCA that help improve genearlization when we data is fed into these large networks. 2. Build a SCA that focuses not on learning a label-free loss function but on learning quality of a concept. ### Review Overall, the paper present a novel idea that offers a unsupervised learning method to assist a supervised learning model to improve its performance. Implementation of this SCA framework is straightforward and demonstrates promising results. This approach is finally contributing to the actual theory of meta-learning and learning to learn research field. SCA framework is a new step towards self-adaptive learning systems. Unfortunately, the experimentation is insufficient and provided little insight into how this framework can help in cases where task domains vary in distribution or in concept.
