2. Which of the following tools is commonly used to explain individual model predictions?
easy
A. Docker
B. Kubernetes
C. Terraform
D. SHAP
Solution
Step 1: Identify explainability tools
SHAP is a popular tool to explain individual model predictions by showing feature impact.
Step 2: Recognize unrelated tools
Docker, Kubernetes, and Terraform are infrastructure and deployment tools, not explainability tools.
Final Answer:
SHAP -> Option D
Quick Check:
Explainability tool = SHAP [OK]
Hint: SHAP explains model predictions; others manage infrastructure [OK]
Common Mistakes:
Choosing Docker or Kubernetes as explainability tools
Confusing infrastructure tools with model explanation tools
Not knowing SHAP purpose
3. Given a model explanation output showing feature importance scores: {'age': 0.4, 'income': 0.3, 'education': 0.2, 'gender': 0.1}, which feature has the highest impact on the prediction?
medium
A. age
B. education
C. income
D. gender
Solution
Step 1: Analyze feature importance scores
The scores indicate how much each feature affects the model's prediction.
Step 2: Identify the highest score
Age has the highest score of 0.4, meaning it impacts the prediction most.
Final Answer:
age -> Option A
Quick Check:
Highest score = age = 0.4 [OK]
Hint: Highest feature score means highest impact [OK]
Common Mistakes:
Picking the second highest score by mistake
Confusing feature names
Ignoring the numeric values
4. You run a LIME explanation but get an error: 'ValueError: input data shape mismatch'. What is the most likely cause?
medium
A. The model is not trained
B. Input data format does not match model expectations
C. LIME is not installed
D. The explanation output is too large
Solution
Step 1: Understand the error message
'ValueError: input data shape mismatch' means the input data shape does not fit what the model expects.
Step 2: Identify cause related to input data
LIME requires input data to match the model's input format exactly; mismatch causes this error.
Final Answer:
Input data format does not match model expectations -> Option B
Quick Check:
Shape mismatch = input format error [OK]
Hint: Check input data shape matches model input [OK]
Common Mistakes:
Assuming model is untrained
Thinking LIME installation causes shape errors
Confusing error with output size issues
5. You want to meet explainability requirements for a credit scoring model to comply with regulations. Which approach best ensures transparency and trust?
hard
A. Use SHAP to explain individual predictions and document feature impacts
B. Only provide overall model accuracy metrics
C. Hide model details to protect intellectual property
D. Deploy the model without any explanation to speed up delivery
Solution
Step 1: Identify explainability needs for compliance
Regulations require clear explanations of how decisions are made to ensure fairness and trust.
Step 2: Choose approach that provides detailed explanations
Using SHAP to explain individual predictions and documenting feature impacts meets transparency and trust needs.
Final Answer:
Use SHAP to explain individual predictions and document feature impacts -> Option A
Quick Check:
Explainability for compliance = SHAP explanations [OK]
Hint: Explain individual predictions clearly for compliance [OK]
Common Mistakes:
Relying only on accuracy without explanations
Hiding model details reduces trust and breaks rules
