U-Sketch: An Efficient Approach for Sketch to Image Diffusion Models

no code implementations27 Mar 2024 Ilias Mitsouras, Eleftherios Tsonis, Paraskevi Tzouveli, Athanasios Voulodimos

Diffusion models have demonstrated remarkable performance in text-to-image synthesis, producing realistic and high resolution images that faithfully adhere to the corresponding text-prompts.

Denoising Image Generation

Automatic inspection of cultural monuments using deep and tensor-based learning on hyperspectral imagery

no code implementations5 Jul 2022 Ioannis N. Tzortzis, Ioannis Rallis, Konstantinos Makantasis, Anastasios Doulamis, Nikolaos Doulamis, Athanasios Voulodimos

In Cultural Heritage, hyperspectral images are commonly used since they provide extended information regarding the optical properties of materials.

Rank-R FNN: A Tensor-Based Learning Model for High-Order Data Classification

no code implementations11 Apr 2021 Konstantinos Makantasis, Alexandros Georgogiannis, Athanasios Voulodimos, Ioannis Georgoulas, Anastasios Doulamis, Nikolaos Doulamis

We hereby propose the Rank-R Feedforward Neural Network (FNN), a tensor-based nonlinear learning model that imposes Canonical/Polyadic decomposition on its parameters, thereby offering two core advantages compared to typical machine learning methods.

BIG-bench Machine Learning General Classification
