BRAILS is a new AI-enabled tool to assist regional-scale simulations. BRAILS utilizes machine learning (ML) and deep learning (DL) to create enhanced building inventory databases of cities. Examples of its capabilities include: (a) The identification of roof shapes to improve the damage and loss calculations for the hurricane workflow. This implementation used data from open street map and images from Google Maps. (b) The identification of soft-story buildings to improve models in earthquake workflows. This implementation used engineering knowledge and a subset of images from Google Street View to train a neural network to automatically classify the remaining images.

pelicunis a Python package that provides tools for assessment of damage and losses due to natural hazards. It uses a stochastic damage and loss model that is based on the methodology described in FEMA P58 (FEMA, 2012). While FEMA P58 aims to assess the seismic performance of a building, with pelicun we want to provide a more versatile, hazard-agnostic tool that will eventually provide loss estimates for other types of assets (e.g. bridges, facilities, pipelines) and lifelines. The underlying loss model was designed with these objectives in mind and it will be gradually extended to have such functionality.

Surf is used to study the spatial variability and hidden patterns in large datasets. Initial alpha versions were implemented for spatial uncertainty quantification. SURF creates surrogate models that assist users in making predictions. This library features both classical random field models and machine-learning algorithms as the backends for spatial uncertainty quantification. It has been incorporated in SimCenter efforts such as the hurricane and earthquake testbeds for uncertainty quantification and data enhancement.
