PhD research on "Counterfactual Video Generation and Evaluation"
Abstract: We propose CSVC, a framework for causally faithful counterfactual video generation using latent diffusion models. By embedding causal graphs into prompts and guiding generation with a vision-language model loss, CSVC can produce realistic, causally consistent counterfactuals. It improves causal effectiveness without fine-tuning, enabling broad applications in media and healthcare.
