Ensuring Model Explainability
Model transparency is crucial for regulatory compliance and stakeholder trust. Employing optimization techniques such as SHAP values can elucidate model predictions. Implementing a Python-based data analysis framework can help. Here’s an example using Pandas and SHAP:
Enhancing Model Explainability with SHAP
import shap
import pandas as pd
from sklearn.ensemble import RandomForestClassifier
# Load your dataset
data = pd.read_csv('credit_data.csv')
X = data.drop('default', axis=1)
y = data['default']
# Train a model
model = RandomForestClassifier()
model.fit(X, y)
# Calculate SHAP values
explainer = shap.Explainer(model, X)
shap_values = explainer(X)
# Plot the SHAP summary
shap.summary_plot(shap_values, X)
What This Code Does:
This code trains a Random Forest model and uses SHAP to calculate feature importance for model interpretability.
Business Impact:
Improved model transparency fosters regulatory compliance and builds stakeholder trust in predictive models.
Implementation Steps:
Install SHAP and necessary libraries, execute the script to visualize model feature impacts.
Expected Result:
SHAP summary plot illustrating feature importance
