Final Project in Catastrophe Modeling.

Catastrophe Modeling: Catastrophe modeling is a discipline within the insurance industry that involves using computer-based models to estimate the potential losses that could result from a catastrophic event, such as a hurricane, earthquake, or terrorist attack. These models help insurers and reinsurers assess their exposure to catastrophic risks and make more informed decisions about pricing, underwriting, and risk management.

AI-based Catastrophe Modeling: AI-based catastrophe modeling refers to the use of artificial intelligence (AI) techniques, such as machine learning and deep learning, to enhance traditional catastrophe modeling approaches. By leveraging AI, insurers can build more accurate and robust models that can capture complex relationships and patterns in data, leading to better risk assessment and decision-making.
