Beyond Low Rank: A Graph-Based Propagation Approach to Tensor Completion for Multi-Acquisition Scenarios

no code implementations6 Dec 2023 Iain Rolland, Sivasakthy Selvakumaran, Andrea Marinoni

Referred to as GraphProp, the method propagates observed entries around a graph-based representation of the tensor in order to recover the missing entries.

Improving embedding of graphs with missing data by soft manifolds

no code implementations29 Nov 2023 Andrea Marinoni, Pietro Lio', Alessandro Barp, Christian Jutten, Mark Girolami

The reliability of graph embeddings directly depends on how much the geometry of the continuous space matches the graph structure.

A graph representation based on fluid diffusion model for data analysis: theoretical aspects and enhanced community detection

no code implementations7 Dec 2021 Andrea Marinoni, Christian Jutten, Mark Girolami

This system provides several constraints and assumptions on the data properties that might be not valid for multimodal data analysis, especially when large scale datasets collected from heterogeneous sources are considered, so that the accuracy and robustness of the outcomes might be severely jeopardized.

Enhancing ensemble learning and transfer learning in multimodal data analysis by adaptive dimensionality reduction

no code implementations8 May 2021 Andrea Marinoni, Saloua Chlaily, Eduard Khachatrian, Torbjørn Eltoft, Sivasakthy Selvakumaran, Mark Girolami, Christian Jutten

Nonetheless, when applied to multimodal datasets (i. e., datasets acquired by means of multiple sensing techniques or strategies), the state-of-theart methods for ensemble learning and transfer learning might show some limitations.

Super-resolution-based Change Detection Network with Stacked Attention Module for Images with Different Resolutions

1 code implementation27 Feb 2021 Mengxi Liu, Qian Shi, Andrea Marinoni, Da He, Xiaoping Liu, Liangpei Zhang

The experimental results demonstrate the superiority of the proposed method, which not only outperforms all baselines -with the highest F1 scores of 87. 40% on the building change detection dataset and 92. 94% on the change detection dataset -but also obtains the best accuracies on experiments performed with images having a 4x and 8x resolution difference.
