Concept Bottleneck Models: Complete Training Walkthrough¶
An Interactive Tutorial for Interpretable Medical Image Diagnosis
What You'll Learn¶
In this notebook, you will:
- 🧠 Understand CBM Architecture - Learn how concept bottlenecks enable interpretability
- 📊 Load & Explore Data - Work with skin cancer diagnosis dataset
- 🏗️ Build a CBM from Scratch - Implement the two-stage architecture
- 🎯 Train & Evaluate - Achieve high concept and task accuracy
- 🔧 Concept Intervention - Correct predictions using human expertise
- 📈 Information Theory - Quantify concept completeness and synergy
- 🎨 Visualize Concepts - See what the model learned
Why Concept Bottleneck Models?¶
Traditional Black-Box Model ❌¶
Image → [Neural Network] → Prediction
(uninterpretable)
Concept Bottleneck Model ✅¶
Image → [Concept Encoder] → Concepts → [Task Predictor] → Prediction
(↑ interpretable + intervention)
Key Advantages:
- ✅ Interpretability: See which concepts drove each prediction
- ✅ Intervention: Correct wrong concepts to fix errors
- ✅ Debugging: Identify when model relies on spurious features
- ✅ Trust: Medical professionals can validate reasoning
Trade-off: ~5% accuracy for full interpretability

================================================== Training Complete! Best Validation F1: 0.7040 Model saved to: ../outputs/notebook_cbm
5. Visualize Training Progress¶
Let's plot the training history to see how the model learned.
In [7]:
import matplotlib.pyplot as plt
# Extract metrics from trainer's history
train_history = trainer.train_history
val_history = trainer.val_history
epochs = list(range(1, len(train_history['total_loss']) + 1))
# Create subplots
fig, axes = plt.subplots(2, 2, figsize=(15, 12))
# Plot total loss (train + val)
axes[0, 0].plot(epochs, train_history['total_loss'], 'b-', label='Train', linewidth=2)
axes[0, 0].plot(epochs, val_history['total_loss'], 'r-', label='Val', linewidth=2)
axes[0, 0].set_xlabel('Epoch')
axes[0, 0].set_ylabel('Total Loss')
axes[0, 0].set_title('Total Loss')
axes[0, 0].legend()
axes[0, 0].grid(True)
# Plot concept loss (train + val)
axes[0, 1].plot(epochs, train_history['concept_loss'], 'b-', label='Train', linewidth=2)

6. Evaluate on Test Set¶
Now let's evaluate the trained model on the test set.
In [9]:
# Load best model for evaluation
print("Loading best model for test evaluation...")
best_model = ConceptBottleneckModel.load(
os.path.join(OUTPUT_DIR, 'best_model.pth'),

)
trainer.model = best_model
print("\nEvaluating on test set...")
test_metrics = trainer.evaluate(test_loader)
print("\n" + "=" * 70)
print("Test Set Performance:")
print("=" * 70)
print(f"Concept Accuracy: {test_metrics['concept_acc']:.4f}")
print(f"Task Accuracy: {test_metrics['task_acc']:.4f}")
print(f"Task F1 Score: {test_metrics['task_f1']:.4f}")
print("=" * 70)
# Save results to file
results_file = os.path.join(OUTPUT_DIR, 'test_results.txt')
with open(results_file, 'w') as f:
f.write(f"Dataset: Derm7pt\n")
f.write(f"Model: ResNet50 + linear predictor\n")
f.write(f"Epochs: {NUM_EPOCHS}\n")
f.write(f"Learning rate: {LEARNING_RATE}\n")
f.write(f"Strategy: joint\n")
f.write(f"\nTest Results:\n")
f.write(f" Concept Accuracy: {test_metrics['concept_acc']:.4f}\n")
f.write(f" Task Accuracy: {test_metrics['task_acc']:.4f}\n")
f.write(f" Task F1 Score: {test_metrics['task_f1']:.4f}\n")
print(f"\n✓ Results saved to: {results_file}")

/home/csc29/projects/SynergyCBM/SkinCBM/src/models/basic_cbm.py:324: FutureWarning: You are using `torch.load` with `weights_only=False` (the current default value), which uses the default pickle module implicitly. It is possible to construct malicious pickle data which will execute arbitrary code during unpickling (See https://github.com/pytorch/pytorch/blob/main/SECURITY.md#untrusted-models for more details). In a future release, the default value for `weights_only` will be flipped to `True`. This limits the functions that could be executed during unpickling. Arbitrary objects will no longer be allowed to be loaded via this mode unless they are explicitly allowlisted by the user via `torch.serialization.add_safe_globals`. We recommend you start setting `weights_only=True` for any use case where you don't have full control of the loaded file. Please open an issue on GitHub for any issues related to this experimental feature. checkpoint = torch.load(path, map_location=device)

7. Concept Intervention - The Magic of CBMs! 🪄¶
This is where CBMs shine: we can intervene on concept predictions to fix errors.
Scenario: Model predicts wrong concepts → wrong diagnosis
Solution: Correct the concepts to ground truth → prediction may improve!
Let's find a test case and demonstrate intervention.
In [10]:
# Find a test case to demonstrate intervention
best_model.eval()
# Get test samples
test_images_batch, test_concepts_batch, test_labels_batch = next(iter(test_loader))
test_images_batch = test_images_batch.to(device)
# Run predictions
with torch.no_grad():
pred_concepts, pred_logits = best_model(test_images_batch)
pred_classes = pred_logits.argmax(dim=1)
# Select first sample
sample_idx = 0
original_image = test_images_batch[sample_idx:sample_idx+1]
original_concepts_flat = pred_concepts[sample_idx] # Shape: [21]
original_logit = pred_logits[sample_idx]
true_concepts = test_concepts_batch[sample_idx] # Shape: [7] (ground truth class per concept)
true_label = test_labels_batch[sample_idx].item()
# Reshape concepts for interpretation: [21] → [7, 3]
original_concepts_reshaped = original_concepts_flat.reshape(7, 3)
pred_concept_classes = original_concepts_reshaped.argmax(dim=1).cpu().numpy()
diagnosis_labels = ['Non-Melanoma', 'Melanoma']
class_labels = ['Absent', 'Regular', 'Irregular']
print("Original Prediction (without intervention):")
print("=" * 70)
print(f"True Label: {diagnosis_labels[true_label]}")
print(f"Predicted: {diagnosis_labels[pred_classes[sample_idx].item()]}")
print(f"Confidence: {torch.softmax(original_logit, dim=0).max():.2%}\n")
print("Concept Predictions vs Ground Truth:")
print("-" * 70)
for i, concept_name in enumerate(CONCEPT_NAMES):
pred_class = int(pred_concept_classes[i])
true_class = int(true_concepts[i].item())

print(f"{match} {concept_name:25s} Pred: {class_labels[pred_class]:10s} GT: {class_labels[true_class]:10s}")
# Intervention: Set concepts to ground truth
print("\n" + "=" * 70)
print("INTERVENTION: Correcting concepts to ground truth")
print("=" * 70)
# Create one-hot encoded concepts from ground truth
intervened_concepts = torch.zeros(1, 7, 3, device=device)
for i in range(7):
gt_class = int(true_concepts[i].item())
intervened_concepts[0, i, gt_class] = 1.0
# Flatten to [1, 21] for model input
intervened_concepts_flat = intervened_concepts.reshape(1, -1)
with torch.no_grad():
intervened_logits = best_model.task_predictor(intervened_concepts_flat)
intervened_pred = intervened_logits.argmax(dim=1).item()
intervened_prob = torch.softmax(intervened_logits[0], dim=0)
print(f"\nAfter Intervention:")
print(f" Predicted: {diagnosis_labels[intervened_pred]}")
print(f" Confidence: {intervened_prob.max():.2%}")
print(f"\nResult: {'✅ Correct!' if intervened_pred == true_label else '❌ Still incorrect'}")
# Show probability change
orig_prob = torch.softmax(original_logit, dim=0)
print(f"\nProbability shift:")
print(f" Melanoma: {orig_prob[1]:.2%} → {intervened_prob[1]:.2%} ({intervened_prob[1] - orig_prob[1]:+.2%})")
print(f" Non-Melanoma: {orig_prob[0]:.2%} → {intervened_prob[0]:.2%} ({intervened_prob[0] - orig_prob[0]:+.2%})")

8. Inspect Learned Concept Weights¶
Since we used a linear task predictor, we can directly inspect which concepts contribute to melanoma diagnosis!
In [12]:
# Get learned weights from linear task predictor
# Shape: [num_classes=2, num_concept_logits=21]
weights = best_model.task_predictor.predictor.weight.detach().cpu().numpy()
print("Task Predictor Weights Shape:", weights.shape)
print(" (num_classes=2, num_concept_logits=7×3=21)")
# For each concept, sum the absolute weights across its 3 classes
concept_importances = []
for concept_idx in range(7):
# Get weights for this concept's 3 classes
start_idx = concept_idx * 3
end_idx = start_idx + 3
# Sum absolute values of melanoma class weights for these 3 classes
melanoma_weight = np.abs(weights[1, start_idx:end_idx]).sum()
concept_importances.append(melanoma_weight)
concept_importances = np.array(concept_importances)
# Visualize
fig, (ax1, ax2) = plt.subplots(1, 2, figsize=(16, 6))
# Bar plot of concept importance
concept_names_display = CONCEPT_NAMES
colors = plt.cm.viridis(np.linspace(0, 1, 7))
ax1.barh(range(len(CONCEPT_NAMES)), concept_importances, color=colors, alpha=0.7, edgecolor='black')
ax1.set_yticks(range(len(CONCEPT_NAMES)))
ax1.set_yticklabels(concept_names_display)
ax1.set_xlabel('Total Absolute Weight (3 classes)', fontsize=12, fontweight='bold')
ax1.set_title('Concept Importance for Melanoma Prediction', fontsize=14, fontweight='bold')
ax1.grid(axis='x', alpha=0.3)
# Sorted by importance
sorted_idx = np.argsort(concept_importances)[::-1]
ax2.bar(range(len(CONCEPT_NAMES)), concept_importances[sorted_idx],
color=colors[sorted_idx], alpha=0.7, edgecolor='black')
ax2.set_xticks(range(len(CONCEPT_NAMES)))
ax2.set_xticklabels([concept_names_display[i] for i in sorted_idx], rotation=45, ha='right')
ax2.set_ylabel('Total Absolute Weight', fontsize=12, fontweight='bold')
ax2.set_title('Concept Ranking (Most Important First)', fontsize=14, fontweight='bold')
ax2.grid(axis='y', alpha=0.3)
plt.tight_layout()
plt.show()
# Print interpretation
print("\n" + "=" * 70)
print("Concept Importance Analysis:")
print("=" * 70)
print("\nRanked by total influence on melanoma prediction:\n")
for rank, idx in enumerate(sorted_idx, 1):
importance = concept_importances[idx]
print(f" {rank}. {concept_names_display[idx]:25s} {importance:.3f}")
print("\n" + "=" * 70)
print("Interpretation:")
print("=" * 70)
print("Higher values = More influence on final diagnosis")
print("These weights show how much the model relies on each concept")
print("for making its melanoma vs non-melanoma decision.")

====================================================================== Concept Importance Analysis: ====================================================================== Ranked by total influence on melanoma prediction: 1.
