Questions and Answers

What is the purpose of the self-attention layer in the encoding component?

  • To determine the length of the longest sentence in the training dataset
  • To connect the encoder and decoder components
  • To help the encoder look at other words in the input sentence as it encodes a specific word (correct)
  • To calculate the word embeddings directly
  • What is the primary function of the embedding layer in a Transformer model?

  • Capture the meaning of each word or token in a vector space (correct)
  • Model complex relationships between input tokens
  • Perform self-attention calculations
  • Apply non-linear transformations to the input sequence
  • Where does the embedding algorithm operate in the encoder-decoder model described?

  • In the decoder's attention layer
  • Only in the decoder layers
  • In the bottom-most encoder (correct)
  • It operates after the self-attention layer
  • In the Transformer architecture, what are the two sub-layers present in each encoder or decoder layer?
