MAQA: A Quantum Framework for Supervised Learning

no code implementations20 Mar 2023 Antonio Macaluso, Matthias Klusch, Stefano Lodi, Claudio Sartori

In its general formulation, MAQA can be potentially adopted as the quantum counterpart of all those models falling into the scheme of aggregation of multiple functions, such as ensemble algorithms and neural networks.

Quantum Splines for Non-Linear Approximations

1 code implementation9 Mar 2023 Antonio Macaluso, Luca Clissa, Stefano Lodi, Claudio Sartori

Quantum Computing offers a new paradigm for efficient computing and many AI applications could benefit from its potential boost in performance.

Enabling Non-Linear Quantum Operations through Variational Quantum Splines

no code implementations8 Mar 2023 Matteo Antonio Inajetovic, Filippo Orazi, Antonio Macaluso, Stefano Lodi, Claudio Sartori

The postulates of quantum mechanics impose only unitary transformations on quantum states, which is a severe limitation for quantum machine learning algorithms.

OptAGAN: Entropy-based finetuning on text VAE-GAN

1 code implementation1 Sep 2021 Paolo Tirotta, Stefano Lodi

We benchmark the results of the VAE-GAN model, and show the improvements brought by our RL finetuning on three widely used datasets for text generation, with results that greatly surpass the current state-of-the-art for the quality of the generated texts.
