Here we study the comparative power of classical and quantum learners for generative modelling within the Probably Approximately Correct (PAC) framework. More specifically we consider the following ta
The task of learning a probability distribution from samples is ubiquitous
across the natural sciences. The output distributions of local quantum circuits
form a particularly interesting class of dist
We propose a new model that generates images through iteratively inverting the heat equation, a pde that locally erases fine-scale information when run over the 2d plane of the image.
Inspired by diffusionmodels and the desirability of coarse-to-fine modelling, we propose a new model that generates images through iteratively inverting the heat equation, a pde that locally erases fine-scale information when run over the 2d plane of the image.
There has been a recent surge in learning generative models for graphs. While
impressive progress has been made on static graphs, work on generative modeling
of temporal graphs is at a nascent stage w
Variational autoencdoers (VAE) are a popular approach to generative
modelling. However, exploiting the capabilities of VAEs in practice can be
difficult. Recent work on regularised and entropic autoen
Variational Autoencoders (VAEs) suffer from degenerated performance, when
learning several successive tasks. This is caused by catastrophic forgetting.
In order to address the knowledge loss, VAEs are
Finding a concrete use case for quantum computers in the near term is still an open question, with machine learning typically touted as one of the first fields which will be impacted by quantum techno
Neural network based data-driven market simulation unveils a new and flexible
way of modelling financial time series without imposing assumptions on the
underlying stochastic dynamics. Though in this
We propose methods for density estimation and data synthesis using a novelform of unsupervised random forests.
Inspired by generative adversarialnetworks, we implement a recursive procedure in which trees gradually learn structural properties of the data through alternating rounds of generation and discrimination.
Natural data observed in $\mathbb{R}^n$ is often constrained to an
$m$-dimensional manifold $\mathcal{M}$, where $m < n$. Current generative
models represent this manifold by mapping an $m$-dimensiona

Among likelihood-based approaches for deep generative modelling, variational
autoencoders (VAEs) offer scalable amortized posterior inference and fast
sampling. However, VAEs are also more and more ou
We propose an automated deepgenerative model using graph neural networks (gnns) to generate synthetic data with highly variable and plausible document layouts that can be used to train document interpretation systems, in this case, specially in digital mailroomapplications.
It is also the first graph-based approach for document layout generation task experimented on administrative document images, in this case, in this case,invoices.
Deep generative models, in the form of neural networks, have been recently used to create synthetic 2d images of natural scenes.
However, the ability to produce high-resolution 3d volumetric imaging data with correct anatomical morphology has been hampered by datascarcity and algorithmic and computational limitations.
Generative adversarial networks have seen rapid development in recent years
and have led to remarkable improvements in generative modelling of images.
However, their application in the audio domain ha

The Hamiltonian of an isolated quantum mechanical system determines its
