DBGDGM: Dynamic Brain Graph Deep Generative Model

no code implementations26 Jan 2023 Alexander Campbell, Simeon Spasov, Nicola Toschi, Pietro Lio

In this paper, we propose a dynamic brain graph deep generative model (DBGDGM) which simultaneously clusters brain regions into temporally evolving communities and learns dynamic unsupervised node embeddings.

An investigation of pre-upsampling generative modelling and Generative Adversarial Networks in audio super resolution

no code implementations30 Sep 2021 James King, Ramon Viñas Torné, Alexander Campbell, Pietro Liò

Our paper compares the pre-upsampling AudioUNet to a new generative model that upsamples the signal before using deep learning to transform it into a more believable signal.
