Try a sample question

In the original LLaVA architecture, how are visual features from a CLIP encoder connected to the language model?

A.A single linear projection layer maps CLIP's visual feature vectors into the LLM's token embedding dimension, converting each image patch feature into a 'visual token'
B.Visual features are concatenated directly with word token embeddings in the embedding lookup layer, with positional IDs assigned as continuations from the last text token
C.A dedicated cross-attention layer in every LLM transformer block attends from text tokens to the visual features stored in a separate parallel image memory bank
D.Visual features are first converted to natural language descriptions using a separate image captioning model before those text descriptions are passed as input to the LLM
