SENSE: Semantic Neural Speech Synthesis from Brain Dynamics via Spatial Graph Encoding

Reconstructing speech from non-invasive brain signals offers a promising pathway for restoring communication in individuals who are cognitively intact but unable to speak. Existing EEG-to-speech approaches formulate this task as acoustic reconstruction, optimizing waveform fidelity while ignoring whether the generated...

DiNGGA: Dirichlet and Noise-Guided Gaussian Avatar for Fine-Grained Facial Detail

This paper proposes DiNGGA (Dirichlet and Noise-Guided Gaussian Avatars), a 3D Dirichlet PDF-based height field defined over each mesh triangle of the face region, enabling explicit modeling of expression-dependent wrinkles and non-rigid surface deformations in head avatar reconstruction.
