K-plex Cover Pooling for Graph Neural Networks

no code implementations NeurIPS Workshop LMCA 2020 Davide Bacciu, Alessio Conte, Roberto Grossi, Francesco Landolfi, Andrea Marino

We introduce a novel pooling technique which borrows from classical results in graph theory that is non-parametric and generalizes well to graphs of different nature and connectivity pattern.

Possible multi-orbital ground state in CeCu$_2$Si$_2$

no code implementations5 Oct 2020 Andrea Amorese, Andrea Marino, Martin Sundermann, Kai Chen, Zhiwei Hu, Thomas Willers, Fadi Choukani, Philippe Ohresser, Javier Herrero-Martin, Stefano Agrestini, Chien-Te Chen, Hong-Ji Lin, Maurits W. Haverkort, Silvia Seiro, Christoph Geibel, Frank Steglich, Liu Hao Tjeng, Gertrud Zwicknagl, Andrea Severing

The crystal-field ground state wave function of CeCu$_2$Si$_2$ has been investigated with linear polarized $M$-edge x-ray absorption spectroscopy from 250mK to 250K, thus covering the superconducting ($T_{\text{c}}$=0. 6K), the Kondo ($T_{\text{K}}$$\approx$20K) as well as the Curie-Weiss regime.

Proximity Search For Maximal Subgraph Enumeration

1 code implementation31 Dec 2019 Alessio Conte, Andrea Marino, Roberto Grossi, Takeaki Uno, Luca Versari

Using known techniques, such as reverse search, the space of all maximal solutions induces an implicit directed graph called "solution graph" or "supergraph", and solutions are enumerated by traversing it; however, nodes in this graph can have exponential out-degree, thus requiring exponential time to be spent on each solution.

Synchronous Context-Free Grammars and Optimal Linear Parsing Strategies

no code implementations25 Nov 2013 Pierluigi Crescenzi, Daniel Gildea, Andrea Marino, Gianluca Rossi, Giorgio Satta

Synchronous Context-Free Grammars (SCFGs), also known as syntax-directed translation schemata, are unlike context-free grammars in that they do not have a binary normal form.
