Inference for Convolutionally Observed Diffusion Processes [PDF]

open access: yesEntropy, 2020
We propose a new statistical observation scheme of diffusion processes named convolutional observation, where it is possible to deal with smoother observation than ordinary diffusion processes by considering convolution of diffusion processes and some ...

Cox process representation and inference for stochastic reaction-diffusion processes. [PDF]

open access: yesNat Commun, 2016
Complex behaviour in many systems arises from the stochastic interactions of spatially distributed particles or agents. Stochastic reaction–diffusion processes are widely used to model such behaviour in disciplines ranging from biology to the social ...

Neural Diffusion Processes [PDF]

open access: yesInternational Conference on Machine Learning, 2022
Neural network approaches for meta-learning distributions over functions have desirable properties such as increased flexibility and a reduced complexity of inference.

Time reversal of diffusion processes under a finite entropy condition [PDF]

open access: yesAnnales De L Institut Henri Poincare-probabilites Et Statistiques, 2021
Motivated by entropic optimal transport, time reversal of diffusion processes is revisited. An integration by parts formula is derived for the carr\'e du champ of a Markov process in an abstract space. It leads to a time reversal formula for a wide class

Elucidating the Design Space of Diffusion-Based Generative Models [PDF]

open access: yesNeural Information Processing Systems, 2022
We argue that the theory and practice of diffusion-based generative models are currently unnecessarily convoluted and seek to remedy the situation by presenting a design space that clearly separates the concrete design choices.

Janus Type Monolayers of S-MoSiN2 Family and Van Der Waals Heterostructures with Graphene: DFT-Based Study

open access: yesNanomaterials, 2022
Novel representative 2D materials of the Janus type family X-M-ZN2 are studied. These materials are hybrids of a transition metal dichalcogenide and a material from the MoSi2N4 family, and they were constructed and optimized from the MoSi2N4 monolayer by

MultiDiffusion: Fusing Diffusion Paths for Controlled Image Generation [PDF]

open access: yesInternational Conference on Machine Learning, 2023
Recent advances in text-to-image generation with diffusion models present transformative capabilities in image quality. However, user controllability of the generated image, and fast adaptation to new tasks still remains an open challenge, currently ...

Innovation Diffusion Processes: Concepts, Models, and Predictions

open access: yesAnnual Review of Statistics and Its Application, 2022
Innovation diffusion processes have attracted considerable research attention for their interdisciplinary character, which combines theories and concepts from disciplines such as mathematics, physics, statistics, social sciences, marketing, economics ...

Modelling of Electron and Thermal Transport in Quasi-Fractal Carbon Nitride Nanoribbons

open access: yesFractal and Fractional, 2022
In this work, using calculations based on the density functional theory, molecular dynamics, non-equilibrium Green functions method, and Monte Carlo simulation, we study electronic and phonon transport in a device based on quasi-fractal carbon nitride ...
