Depth-Adaptive BERT Models
Depth-adaptive models are a type of dynamic network that improves BERT's inference efficiency. The core principle is to dynamically determine the optimal number of layers required to process a given token. The model can then exit early from an intermediate layer, skipping the remaining layers in the stack to reduce computation.

A team of engineers is tasked with optimizing a large language model for real-time text summarization of news articles. They observe that the model's processing time is a major bottleneck. To address this, they implement a mechanism that, for each article, dynamically decides to skip processing certain less-informative sentences entirely, thereby reducing the total amount of text fed through the model's most computationally expensive components. Which principle of efficient model inference does this approach best exemplify?

A standard 12-layer language model and a depth-adaptive 12-layer language model are both used for inference on two different input sentences. Sentence 1 is 'The sky is blue.' Sentence 2 is 'The philosophical underpinnings of existentialism challenge traditional notions of predetermined essence.' How would the computational cost for processing these two sentences likely compare between the two models?
A depth-adaptive language model is processing the sentence: 'The intricate legal arguments presented by the defense were compelling.' Which of the following best explains why the token for 'the' would likely exit the model's layers earlier than the token for 'intricate'?
