Enhancing crop classification accuracy by synthetic SAR-Optical data generation using deep learning

no code implementations3 Feb 2024 Ali Mirzaei, Hossein Bagheri, Iman Khosravi

In this research, We explore the effectiveness of conditional tabular generative adversarial network (CTGAN) as a synthetic data generation method based on a deep learning network, in addressing the challenge of limited training data for minority classes in crop classification using the fusion of SAR-optical data.

Deep Feature Selection using a Teacher-Student Network

1 code implementation17 Mar 2019 Ali Mirzaei, Vahid Pourahmadi, Mehran Soltani, Hamid Sheikhzadeh

In this paper, we present a novel teacher-student feature selection (TSFS) method in which a 'teacher' (a deep neural network or a complicated dimension reduction method) is first employed to learn the best representation of data in low dimension.

Deep Learning-Based Channel Estimation

4 code implementations13 Oct 2018 Mehran Soltani, Vahid Pourahmadi, Ali Mirzaei, Hamid Sheikhzadeh

This scheme considers the pilot values, altogether, as a low-resolution image and uses an SR network cascaded with a denoising IR network to estimate the channel.
