Graded Quiz: Generative AI Architecture :Generative AI and LLMs: Architecture and Data Preparation (IBM AI Engineering Professional Certificate) Answers 2025
1. Best use of GANs for Rosy’s fashion app
❌ Utilizing natural language for chatbot conversations
❌ Translating text between languages
✅ Generating realistic images based on training data
❌ Generating text from voice conversations
Explanation:
GANs are powerful for image generation — perfect for fashion design, virtual try-ons, or creating new clothing styles.
2. Best architecture for a memory-efficient chatbot on limited hardware
✅ Recurrent neural networks (RNNs)
❌ BERT
❌ Variational autoencoders (VAEs)
❌ GANs
Explanation:
RNNs are lightweight and generate responses based on immediate previous context, making them ideal for resource-constrained devices.
3. Which model primarily functions as a decoder?
❌ BERT
❌ BART
✅ Generative Pretrained Transformer (GPT)
❌ T5
Explanation:
GPT is a decoder-only model specialized in text generation.
4. Which GenAI capability simplifies complex patient test results?
❌ Predict patient results
✅ Generate contextually relevant text from existing data
❌ Compress data
❌ Create 3D images
Explanation:
GenAI models can rewrite and simplify medical information into understandable language.
5. Why are GPT models called “large”?
❌ They have high memory requirements
❌ They are used in many industries
✅ They contain billions of parameters
❌ They are applied to many tasks
Explanation:
GPTs are called “large” because of their massive parameter count, which enables sophisticated language understanding and generation.
