The Department of Defense (DoD) is seeking proposals for the topic of "Deep Rational 3D Geospatial Analytics for Generative AI" as part of the SBIR 23.3 BAA. The specific agency involved is the National Geospatial-Intelligence Agency (NGA). The objective of this solicitation is to develop advanced AI/ML algorithms that combine generative AI with discriminative AI to enhance 3D geospatial analytics. The current AI/ML techniques for geospatial analysis lack the ability to exploit the rich contextual relational information in the scene. The proposed approaches should leverage generative AI in the form of large language models capable of generating relationships between objects while capturing the relational diversity present in the real world. The proposed approaches must combine generative AI with discriminative AI such as deep convolutional neural network models for segmentation and classification. Phase I of the project requires demonstrating a proof-of-concept approach using open source 3D datasets. Phase II involves optimizing and implementing the selected generative AI and discriminative AI into an end-to-end model. Phase III focuses on the dual-use applications of the developed software, including DoD use cases, civil engineering missions, and commercial robotics applications. The project duration, funding specifics, and performance goals are not provided in the document. For more information, refer to the solicitation agency URL: https://www.defensesbirsttr.mil/.
