NEW QUESTION # 22
Which statement best describes the role of encoder and decoder models in natural language processing?
- A. Encoder models are used only for numerical calculations, whereas decoder models are used to interpret the calculated numerical values back into text.
- B. Encoder models take a sequence of words and predict the next word in the sequence, whereas decoder models convert a sequence of words into a numerical representation.
- C. Encoder models convert a sequence of words into a vector representation, and decoder models take this vector representation to sequence of words.
- D. Encoder models and decoder models both convert sequence* of words into vector representations without generating new text.
Answer: C
NEW QUESTION # 23
ow do Dot Product and Cosine Distance differ in their application to comparing text embeddings in natural language?
- A. Dot Product assesses the overall similarity in content, whereas Cosine Distance measures topical relevance.
- B. Dot Product measures the magnitude and direction vectors, whereas Cosine Distance focuses on the orientation regardless of magnitude.
- C. Dot Product calculates the literal overlap of words, whereas Cosine Distance evaluates the stylistic similarity.
- D. Dot Product is used for semantic analysis, whereas Cosine Distance is used for syntactic comparisons.
