Generative Learning of Continuous Data by Tensor Networks

no code implementations31 Oct 2023 Alex Meiburg, Jing Chen, Jacob Miller, Raphaëlle Tihon, Guillaume Rabusseau, Alejandro Perdomo-Ortiz

Beyond their origin in modeling many-body quantum systems, tensor networks have emerged as a promising class of models for solving machine learning problems, notably in unsupervised generative learning.

A Framework for Demonstrating Practical Quantum Advantage: Racing Quantum against Classical Generative Models

no code implementations27 Mar 2023 Mohamed Hibat-Allah, Marta Mauri, Juan Carrasquilla, Alejandro Perdomo-Ortiz

In this study, we build over a proposed framework for evaluating the generalization performance of generative models, and we establish the first quantitative comparative race towards practical quantum advantage (PQA) between classical and quantum generative models, namely Quantum Circuit Born Machines (QCBMs), Transformers (TFs), Recurrent Neural Networks (RNNs), Variational Autoencoders (VAEs), and Wasserstein Generative Adversarial Networks (WGANs).

Do Quantum Circuit Born Machines Generalize?

no code implementations27 Jul 2022 Kaitlin Gili, Mohamed Hibat-Allah, Marta Mauri, Chris Ballance, Alejandro Perdomo-Ortiz

To the best of our knowledge, this is the first work in the literature that presents the QCBM's generalization performance as an integral evaluation metric for quantum generative models, and demonstrates the QCBM's ability to generalize to high-quality, desired novel samples.

Generalization Metrics for Practical Quantum Advantage in Generative Models

no code implementations21 Jan 2022 Kaitlin Gili, Marta Mauri, Alejandro Perdomo-Ortiz

Using the sample-based approach proposed here, any generative model, from state-of-the-art classical generative models such as GANs to quantum models such as Quantum Circuit Born Machines, can be evaluated on the same ground on a concrete well-defined framework.

GEO: Enhancing Combinatorial Optimization with Classical and Quantum Generative Models

no code implementations15 Jan 2021 Javier Alcazar, Alejandro Perdomo-Ortiz

The first uses data points previously evaluated by any quantum or classical optimizer, and we show how TN-GEO improves the performance of the classical solver as a standalone strategy in hard-to-solve instances.

Robust Implementation of Generative Modeling with Parametrized Quantum Circuits

no code implementations23 Jan 2019 Vicente Leyton-Ortega, Alejandro Perdomo-Ortiz, Oscar Perdomo

Since each of the training curves requires the execution of thousands of quantum circuits in the quantum computer, such a robust study remained a steep challenge for most hybrid platforms available today.

A generative modeling approach for benchmarking and training shallow quantum circuits

1 code implementation23 Jan 2018 Marcello Benedetti, Delfina Garcia-Pintos, Oscar Perdomo, Vicente Leyton-Ortega, Yunseong Nam, Alejandro Perdomo-Ortiz

Hybrid quantum-classical algorithms provide ways to use noisy intermediate-scale quantum computers for practical applications.

Opportunities and challenges for quantum-assisted machine learning in near-term quantum computers

no code implementations31 Aug 2017 Alejandro Perdomo-Ortiz, Marcello Benedetti, John Realpe-Gómez, Rupak Biswas

We argue that to reach this target, the focus should be on areas where ML researchers are struggling, such as generative models in unsupervised and semi-supervised learning, instead of the popular and more tractable supervised learning techniques.

Quantum-Assisted Learning of Hardware-Embedded Probabilistic Graphical Models

no code implementations8 Sep 2016 Marcello Benedetti, John Realpe-Gómez, Rupak Biswas, Alejandro Perdomo-Ortiz

Mainstream machine-learning techniques such as deep learning and probabilistic programming rely heavily on sampling from generally intractable probability distributions.

Bayesian Network Structure Learning Using Quantum Annealing

no code implementations15 Jul 2014 Bryan O'Gorman, Alejandro Perdomo-Ortiz, Ryan Babbush, Alan Aspuru-Guzik, Vadim Smelyanskiy

The logical structure resulting from the mapping has the appealing property that it is instance-independent for a given number of Bayesian network variables, as well as being independent of the number of data cases.

A Quantum Annealing Approach for Fault Detection and Diagnosis of Graph-Based Systems

2 code implementations30 Jun 2014 Alejandro Perdomo-Ortiz, Joseph Fluegemann, Sriram Narasimhan, Rupak Biswas, Vadim N. Smelyanskiy

Diagnosing the minimal set of faults capable of explaining a set of given observations, e. g., from sensor readouts, is a hard combinatorial optimization problem usually tackled with artificial intelligence techniques.
