My3DGen: A Scalable Personalized 3D Generative Model

no code implementations11 Jul 2023 Luchao Qi, Jiaye Wu, Annie N. Wang, Shengze Wang, Roni Sengupta

Another challenge of personalization is the limited number of training images available for each individual, which often leads to overfitting when using full fine-tuning methods.
