Key Concepts in Supervised Fine-Tuning for AI Explainability

Supervised fine-tuning is a machine learning technique that involves refining pre-trained models using labeled datasets to improve their performance on specific tasks. When applied to AI explainability, this process focuses on enhancing the model’s ability to provide interpretable outputs. Key concepts include:

• Pre-trained Models: These are AI models trained on large datasets to capture general patterns. Fine-tuning adapts these models to specific tasks or domains.
• Labeled Data: Supervised learning relies on datasets where inputs are paired with corresponding outputs, enabling the model to learn relationships between them.
• Explainability Metrics: These metrics evaluate how well a model’s outputs can be understood by humans, such as feature importance scores or decision pathways.
• Domain-Specific Adjustments: Fine-tuning often involves tailoring models to specific industries or applications, ensuring relevance and accuracy.
