AI0-001 AI Concepts and Foundations Practice Question
A healthcare provider wants to use AI to predict patient readmission risk. They have structured data (age, diagnosis, lab results) and unstructured clinical notes. Which approach is most appropriate?
⚠ Common exam trap
A common mix-up: candidates assume a single model type (like CNN or RNN) is sufficient for all data, overlooking the need to combine structured and unstructured data through a multimodal architecture.

Correct answer & explanation
✓
Multimodal model combining structured and text embeddings
The scenario involves both structured data (age, diagnosis, lab results) and unstructured clinical notes. A multimodal model can process both types by combining embeddings from text (e.g., via a transformer or RNN) with structured features, enabling the model to learn cross-modal patterns that improve readmission risk prediction. This approach leverages the complementary strengths of structured and unstructured data, which is essential for capturing the full clinical picture.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Convolutional neural network (CNN) on clinical notes
Why it's wrong here
CNNs are typically used for images, not text; NLP models are better.
- ✗
Recurrent neural network (RNN) on structured data
Why it's wrong here
RNNs are designed for sequential data, not tabular structured data.
- ✗
Logistic regression on structured data only
Why it's wrong here
This ignores valuable unstructured clinical notes.
- ✓
Multimodal model combining structured and text embeddings
Why this is correct
A multimodal model can process both structured data and text, leveraging all available information.
