Exploring Image Transformations with?Diffusion Models: A Survey of?Applications and?Implementation Cf diffusion models in computer vision, specially in the branch of image transformations. The objective of this survey is to provide an overview of state-of-the-art applications of diffusion models in image transformations, including image inpainting, super-resolution, restoration, translation, and e

This time-consuming, three-step process is a result of using subgrad

Diversity in?Deep Generative Models and?Generative AIshow impressive results when constructing objects similar to those in a training ensemble. However, the generation of new objects builds mainly on the understanding of the hidden structure of the training dataset followed by a sampling from a multi-dimensional normal variable. In particular each sam

Improving Portfolio Performance Using a?Novel Method for?Predicting Financial Regimes ante prediction of regimes, leading to substantial performance improvements over the earlier model, over all three asset classes considered (equities, commodities, and foreign exchange), over a test period of four years. The proposed new model is also benchmarked over this same period against a hid

Alternating Mixed-Integer Programming and?Neural Network Training for?Approximating Stochastic Two-Srameters with adjustable decision variables. In case the adjustable or second-stage variables contain discrete decisions, the corresponding 2SPs are known to be .-complete. The standard approach of forming a single-stage deterministic equivalent problem can be computationally challenging even for sm
