Exploring the impact of automated vehicles lane-changing behavior on urban network efficiency

no code implementations26 Sep 2023 Alberto Pelizza, Federico Orsini, Sefa Yilmaz-Niewerth, Riccardo Rossi, Bernhard Friedrich

While automated vehicle (AV) research has grown steadily in recent years, the impact of automated lane changing behavior on transportation systems remains a largely understudied topic.

Learning ground states of gapped quantum Hamiltonians with Kernel Methods

no code implementations15 Mar 2023 Clemens Giuliani, Filippo Vicentini, Riccardo Rossi, Giuseppe Carleo

Neural network approaches to approximate the ground state of quantum hamiltonians require the numerical solution of a highly nonlinear optimization problem.

Positive-definite parametrization of mixed quantum states with deep neural networks

no code implementations27 Jun 2022 Filippo Vicentini, Riccardo Rossi, Giuseppe Carleo

We introduce the Gram-Hadamard Density Operator (GHDO), a new deep neural-network architecture that can encode positive semi-definite density operators of exponential rank with polynomial resources.

From Tensor Network Quantum States to Tensorial Recurrent Neural Networks

1 code implementation24 Jun 2022 Dian Wu, Riccardo Rossi, Filippo Vicentini, Giuseppe Carleo

We show that any matrix product state (MPS) can be exactly represented by a recurrent neural network (RNN) with a linear memory update.

Mott insulating states with competing orders in the triangular lattice Hubbard model

no code implementations25 Feb 2021 Alexander Wietek, Riccardo Rossi, Fedor Šimkovic IV, Marcel Klett, Philipp Hansmann, Michel Ferrero, E. Miles Stoudenmire, Thomas Schäfer, Antoine Georges

We propose a scenario in which time-reversal symmetry-broken states compete with stripy-spin states at lowest temperatures.

Many-Configuration Markov-Chain Monte Carlo

no code implementations10 Feb 2021 Fedor Šimkovic, Riccardo Rossi

We propose a minimal generalization of the celebrated Markov-Chain Monte Carlo algorithm which allows for an arbitrary number of configurations to be visited at every Monte Carlo step.
