Self-learning Decision Tree

A Self-learning Decision Tree is an advanced algorithm that automatically evolves its structure and rules based on new data via a feedback loop. Unlike static models, it adapts to changing environments. Its application in risk management must align with governance frameworks like ISO/IEC 42001 for the AI lifecycle and the NIST AI Risk Management Framework (AI RMF) for monitoring and transparency. Positioned within the 'Risk Assessment' and 'Risk Treatment' phases of ISO 31000, it serves as an automated tool for identifying and responding to emerging risks, offering superior accuracy over time compared to traditional, static models.

Implementation involves three key steps. First, establish the risk context (e.g., fraud detection) and train a baseline model with historical data, per ISO 31000 guidelines. Second, deploy the model and create an automated feedback loop to capture actual outcomes from analysts. Third, implement an automated retraining pipeline triggered by new data, and continuously monitor model performance (e.g., accuracy, drift) as recommended by the NIST AI RMF's 'Measure' function. A Taiwanese financial firm using this method increased its detection rate for new phishing scams by 25% and reduced manual review cases by 40% within three months.

Taiwanese enterprises face three main challenges: 1) Poor data quality and siloed systems, which hinder effective model training. 2) Regulatory demands for transparency and explainability, especially in finance and healthcare, which can be difficult with evolving models. 3) A shortage of talent skilled in both MLOps and specific business domains. To overcome these, companies should initiate data governance projects (following ISO/IEC 38505-1), use eXplainable AI (XAI) tools to ensure transparency, and partner with expert consultants while leveraging cloud AI platforms to manage costs and bridge the talent gap.
