EvaluatingRAGsystems,however,presentsseveralchallenges: (1) modular complexity: The modular nature of RAG systems, comprising both a retriever and a generator, complicates the design of effective evaluation metrics. It is crucial to establish metrics that can holistically assess the entire system as well as evaluate the individual modules and their interplay [53],allowing for fully understanding the sources ofthe errors and misses and howthey aregenerated.

Foundation models are trained on increasingly immense and opaque datasets.

During optimization, contrastive learning keeps the different modalities separated by a certain distance, which is influenced by the temperature parameter in the loss function. Our experiments further demonstrate that varying the modality gap distance has a significant impact in improving the model's downstream zero-shot classification performance and fairness.

How do we program home robots to perform a wide variety of personalized everyday tasks?

To enable models to learn better representation spaces that simulate the real world, the larger the dataset and the richer the physical knowledge contained inthe videos, the better the training effect. Researchers often construct these large-scale datasets through web scraping.

Such error correlations not only affect the model's ability to make robust predictions but also
