Mechanism of Prompt Tuning at the Embedding Layer

Prefix Tuning (Deep Prompt Tuning)

A machine learning team is adapting a very large pre-trained language model for a new, specialized task. They decide to use a method where only a small set of new, continuous vectors added to the input are trained, while the millions of original model parameters remain unchanged. What is the most significant advantage of this approach?

Two research teams are adapting a large, pre-trained language model for a sentiment analysis task.

• Team Alpha freezes all the original model weights and prepends a small sequence of trainable vectors to the input text's embeddings. These new vectors are the only parameters updated during training.
• Team Beta also freezes the original model weights but inserts a small set of trainable vectors into each layer of the model architecture, which are then updated during training.

Based on these descriptions, which team is correctly implementing the technique where adaptation is achieved exclusively by manipulating the input representation fed into the first layer of the model?
