Try a sample question

CLIP trains an image encoder and a text encoder jointly. What is the training objective that connects them?

A.Contrastive loss (InfoNCE) that pulls matching image-text pairs together while pushing N-1 non-matching pairs apart within each batch
B.Mean squared error applied directly between image embeddings and text embeddings for all matching pairs in a batch, training the encoders to produce numerically identical vectors
C.Cross-entropy classification loss on ImageNet category labels, jointly training both encoders to predict the same fixed set of object categories
D.Triplet loss using a fixed anchor image, a positive matching text description, and a hard-negative text mined from semantically similar but non-matching web captions
