Parallel and Limited Data Voice Conversion Using Stochastic Variational Deep Kernel Learning

no code implementations8 Sep 2023 Mohamadreza Jafaryani, Hamid Sheikhzadeh, Vahid Pourahmadi

On the other hand, statistical methods are effective with limited data but have difficulties in modelling complex mapping functions.

Fast Classification with Sequential Feature Selection in Test Phase

no code implementations25 Jun 2023 Ali Mirzaei, Vahid Pourahmadi, Hamid Sheikhzadeh, Alireza Abdollahpourrostam

During the test phase, the proposed approach utilizes Fisher scores for feature ranking to identify the most important feature at each step.

Progressive Transmission using Recurrent Neural Networks

1 code implementation3 Aug 2021 Mohammad Sadegh Safari, Vahid Pourahmadi, Patrick Mitran, Hamid Sheikhzadeh

The transmitter aims to send the data to the receiver as fast as possible and with as few channel uses as possible (as channel conditions permit) while the receiver refines its estimate after each channel use.

Propagation Channel Modeling by Deep learning Techniques

no code implementations19 Aug 2019 Shirin Seyedsalehi, Vahid Pourahmadi, Hamid Sheikhzadeh, Ali Hossein Gharari Foumani

This paper presents a novel propagation channel model which considers the time-frequency response of the channel as an image.

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.
