Graph neural networks : operators and architectures

Grattarola, Daniele ; Alippi, Cesare (Dir.) ; Livi, Lorenzo (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2021 ; 2021INFO014.

This thesis explores the field of graph neural networks, a class of deep learning models designed to learn representations of graphs. We organise the work into two parts. In the first part, we focus on the essential building blocks of graph neural networks. We present three novel operators for learning graph representations: one graph convolutional layer and two methods for pooling. We put...

Exploring, understanding, and promoting pluralistic strategies for (qualitative) research

Hoorani, Bareerah Hafeez ; Gibbert, Michael (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2021 ; 2021COM004.

There have been growing calls in the field of management for pluralistic research, primarily because it allows for scientific discovery and advancement. However, despite these calls, the field of management is still homogenous in its research approaches and practices. This motivates the aim of this thesis, which is to explore, understand and promote pluralistic (qualitative) research. The...

Phylogeny, taxonomy, and biogeography of Pterocarya (Juglandaceae)

Song, Yi-Gang ; Li, Ying ; Meng, Hong-Hu ; Fragnière, Yann ; Ge, Bin-Jie ; Sakio, Hitoshi ; Yousefzadeh, Hamed ; Bétrisey, Sébastien ; Kozlowski, Gregor

In: Plants, 2020, vol. 9, no. 11, p. 1524

Relict species play an important role in understanding the biogeography of intercontinental disjunctions. Pterocarya (a relict genus) is the valuable model taxon for studying the biogeography of East Asian versus southern European/West Asian disjunct patterns. This disjunction has not been as well studied as others (e.g., between Eastern Asia and North America). Several phylogenetic studies...
