Extended Deep Adaptive Input Normalization for Preprocessing Time Series Data for Neural Networks

1 code implementation23 Oct 2023 Marcus A. K. September, Francesco Sanna Passino, Leonie Goldmann, Anton Hinel

Data preprocessing is a crucial part of any machine learning pipeline, and it can have a significant impact on both performance and training efficiency.

Latent structure blockmodels for Bayesian spectral graph clustering

1 code implementation4 Jul 2021 Francesco Sanna Passino, Nicholas A. Heard

Furthermore, the presence of communities within the network might generate community-specific submanifold structures in the embedding, but this is not explicitly accounted for in most statistical models for networks.

Mutually exciting point process graphs for modelling dynamic networks

1 code implementation11 Feb 2021 Francesco Sanna Passino, Nicholas A. Heard

The model combines mutually exciting point processes to estimate dependencies between events and latent space models to infer relationships between the nodes.

Spectral clustering on spherical coordinates under the degree-corrected stochastic blockmodel

1 code implementation9 Nov 2020 Francesco Sanna Passino, Nicholas A. Heard, Patrick Rubin-Delanchy

The proposed method is based on a transformation of the spectral embedding to spherical coordinates, and a novel modelling assumption in the transformed space.

Bayesian estimation of the latent dimension and communities in stochastic blockmodels

1 code implementation6 Apr 2019 Francesco Sanna Passino, Nicholas A. Heard

In this article, a novel Bayesian model for simultaneous and automatic selection of the appropriate dimension of the latent space and the number of blocks is proposed.
