About Wei Duan
I’m a Data Scientist with a Ph.D. and over 8 years of experience driving data-driven innovation in the insurance and telematics space. My work sits at the intersection of statistical modeling, deep learning, and business strategy—translating complex data into clear, actionable solutions.I specialize in interpretable machine learning, model drift diagnostics, and AI model deployment at scale. Recently, I led the development of a hybrid CNN + metadata model to detect AI-generated images in claims processing, reducing fraud risk. I also conducted cross-functional analyses to trace model performance issues back to vendor data shifts—leading to a model transition that improved loss ratios by 3–4 points and delivered $8M in premium impact.In addition to building models, I’m passionate about ensuring they’re reliable, fair, and understood. I frequently use SHAP to make model decisions transparent and build trust with stakeholders. Whether it’s evaluating new data sources for electric vehicles or launching deep learning pilots to flag aggressive driving behavior, I bring a hands-on and forward-thinking approach to solving high-impact business problems.Tools & Tech: Python, SQL, PySpark, PyTorch, TensorFlow, SHAP, SageMaker Studio, Tableau, XGBoostDomains: Insurance, Telematics, Fraud Detection, Explainable AI, Recommendation SystemsLet’s connect if you’re working on challenges in responsible AI, behavioral modeling, or large-scale predictive systems.
