In attempting to investigate the attrition of a large target complex (raid) caused by attacking manned or unmanned interceptors, the analogy to the diffusion of electrons or neutrons in suitable media, or similarly, radiation transport in a stellar atmosphere, suggests itself.

Market prices of financial assets often show jumps caused by unpredictable events or news. The market closing-opening is also a source of price jumps. The pure Brownian motion based diffusion models do not admit large asset price move in a short period of time. Adding jumps to diffusion can show skewed distributions with fat tail which are difficult to

Proceedings of the AAAI Conference on Artificial Intelligence
Diffusion Models (DMs) offer robust tools for addressing uncertainty and enhancing adaptability in robotics. This work explores their application to trajectory generation, 3D image synthesis, and interpretable scene understanding. For trajectory planning, we propose using colored Gaussian noise to improve robustness and temporal coherence.

Diffusion Models for Attribution
Proceedings of the AAAI Conference on Artificial IntelligenceIn high-stakes domains such as healthcare, finance, and law, the need for explainable AI is critical. Traditional methods for generating attribution maps, including white-box approaches relying on gradients and black-box techniques that perturb inputs, face challenges like gradient vanishing, blurred attributions, and computational inefficiencies.

Physics-Informed Diffusion Models
International Conference on Learning RepresentationsGenerative models such as denoising diffusion models are quickly advancing their ability to approximate highly complex data distributions. They are also increasingly leveraged in scientific machine learning, where samples from the implied data ...

Models of technology diffusion
Research Policy, 2000Abstract The literature on new technology diffusion is vast, and it spills over many conventional disciplinary boundaries. This paper surveys the literature by focusing on alternative explanations of the dominant stylized fact: that the usage of new technologies over time typically follows an S-curve.

This work presents a simple solution for the diffuse double layer model, applicable to calculation of surface speciation as well as to simulation of ionic adsorption within the diffuse layer of solution in arbitrary salt media. Based on Poisson-Boltzmann equation, the Gaines-Thomas selectivity coefficient for uni-bivalent exchange on clay, K(GT)(Me(2+)/
