The document outlines several thesis proposal topics in the areas of explainable artificial intelligence (AI), natural language processing (NLP), image analysis, security, and data science. Some key proposals include developing techniques for semantic clustering of words to label images for explainability, using large language models to guide investigative decisions, and generating realistic simulated data to test national security analysis tools. The proposals cover a range of technologies including deep learning, computer vision, NLP, and generative models.
