You have a dataset with sarcastic and negated sentences. Which model architecture best captures both contexts for sentiment prediction?
AA recurrent neural network (RNN) with attention mechanism
BA simple bag-of-words model without context awareness
CA linear regression model on word counts
DA decision tree using only sentence length
Step-by-Step Solution
Solution:

  1. Step 1: Identify model needs

    Sarcasm and negation require understanding word order and context, which simple models lack.

  2. Step 2: Choose suitable architecture

    RNN with attention captures sequence and focuses on important words, handling sarcasm and negation well.

  3. Final Answer:

    A recurrent neural network (RNN) with attention mechanism -> Option A

  4. Quick Check:

    Context-aware RNN with attention best for sarcasm and negation [OK]
Quick Trick: Use RNN with attention to capture context and sarcasm [OK]
Common Mistakes:
MISTAKES
  • Using bag-of-words ignoring word order
  • Choosing linear models for complex context
  • Relying on sentence length only
