EmbedTalk: Talking Head Synthesis using Gaussian Embeddings
Arpita Saggar, Jonathan C. Darling, Duygu Sarikaya +1
Deformable 3D Gaussian Splatting (3DGS) has emerged as a popular method for real-time talking head synthesis, offering high-quality renderings at low latency. Tri-planes are a comm…
DisentangleFormer: Spatial-Channel Decoupling for Multi-Channel Vision
Jiashu Liao, Pietro Liò, Marc de Kamps +1
Vision Transformers face a fundamental limitation: standard self-attention jointly processes spatial and channel dimensions, leading to entangled representations that prevent indep…
Score Before You Speak: Improving Persona Consistency in Dialogue Generation using Response Quality Scores
Arpita Saggar, Jonathan C. Darling, Vania Dimitrova +2
Persona-based dialogue generation is an important milestone towards building conversational artificial intelligence. Despite the ever-improving capabilities of large language model…
Can Diffusion Models Bridge the Domain Gap in Cardiac MR Imaging?
Xin Ci Wong, Duygu Sarikaya, Kieran Zucker +2
Magnetic resonance (MR) imaging, including cardiac MR, is prone to domain shift due to variations in imaging devices and acquisition protocols. This challenge limits the deployment…
