Deep Unfolding for Iterative Stripe Noise Removal

1 code implementation27 Sep 2022 Zeshan Fayyaz, Daniel Platnick, Hannan Fayyaz, Nariman Farsad

As the applications of degraded infrared images are limited, it is crucial to effectively preserve original details.

MICAL: Mutual Information-Based CNN-Aided Learned Factor

1 code implementation6 Jun 2022 Bahareh Salafian, Eyal Fishel Ben-Knaan, Nir Shlezinger, Sandrine de Ribaupierre, Nariman Farsad

Since the soft estimates obtained as the combined features from the neural MI estimator and the CNN do not capture the temporal correlation between different EEG blocks, we use them not as estimates of the seizure state, but to compute the function nodes of a factor graph.

A Perspective on Neural Capacity Estimation: Viability and Reliability

no code implementations22 Mar 2022 Farhad Mirkarimi, Stefano Rini, Nariman Farsad

These estimators ar referred to as neural mutual information estimation (NMIE)s. NMIEs differ from other approaches as they are data-driven estimators.

CNN-Aided Factor Graphs with Estimated Mutual Information Features for Seizure Detection

no code implementations11 Mar 2022 Bahareh Salafian, Eyal Fishel Ben-Knaan, Nir Shlezinger, Sandrine de Ribaupierre, Nariman Farsad

We then use a 1D-CNN to extract extra features from the EEG signals and use both features to estimate the probability of a seizure event.~Finally, learned factor graphs are employed to capture the temporal correlation in the signal.

Neural Capacity Estimators: How Reliable Are They?

1 code implementation14 Nov 2021 Farhad Mirkarimi, Stefano Rini, Nariman Farsad

Recently, several methods have been proposed for estimating the mutual information from sample data using deep neural networks and without the knowing closed form distribution of the data.

Learned Factor Graphs for Inference from Stationary Time Sequences

no code implementations5 Jun 2020 Nir Shlezinger, Nariman Farsad, Yonina C. Eldar, Andrea J. Goldsmith

Learned factor graph can be realized using compact neural networks that are trainable using small training sets, or alternatively, be used to improve upon existing deep inference systems.

Data-Driven Symbol Detection via Model-Based Machine Learning

no code implementations14 Feb 2020 Nariman Farsad, Nir Shlezinger, Andrea J. Goldsmith, Yonina C. Eldar

The design of symbol detectors in digital communication systems has traditionally relied on statistical channel models that describe the relation between the transmitted symbols and the observed signal at the receiver.

Data-Driven Factor Graphs for Deep Symbol Detection

no code implementations31 Jan 2020 Nir Shlezinger, Nariman Farsad, Yonina C. Eldar, Andrea J. Goldsmith

In particular, we propose to use machine learning (ML) tools to learn the factor graph, instead of the overall system task, which in turn is used for inference by message passing over the learned graph.

Deep Neural Network Symbol Detection for Millimeter Wave Communications

no code implementations25 Jul 2019 Yun Liao, Nariman Farsad, Nir Shlezinger, Yonina C. Eldar, Andrea J. Goldsmith

This paper proposes to use a deep neural network (DNN)-based symbol detector for mmWave systems such that CSI acquisition can be bypassed.

ViterbiNet: A Deep Learning Based Viterbi Algorithm for Symbol Detection

1 code implementation26 May 2019 Nir Shlezinger, Nariman Farsad, Yonina C. Eldar, Andrea J. Goldsmith

Our numerical evaluations demonstrate that the performance of ViterbiNet, which is ignorant of the CSI, approaches that of the CSI-based Viterbi algorithm, and is capable of tracking time-varying channels without needing instantaneous CSI or additional training data.

Sliding Bidirectional Recurrent Neural Networks for Sequence Detection in Communication Systems

no code implementations19 Feb 2018 Nariman Farsad, Andrea Goldsmith

The design and analysis of communication systems typically rely on the development of mathematical models that describe the underlying communication channel.

Deep Learning for Joint Source-Channel Coding of Text

1 code implementation19 Feb 2018 Nariman Farsad, Milind Rao, Andrea Goldsmith

We consider the problem of joint source and channel coding of structured data such as natural language over a noisy channel.

Neural Network Detection of Data Sequences in Communication Systems

no code implementations31 Jan 2018 Nariman Farsad, Andrea Goldsmith

We consider detection based on deep learning, and show it is possible to train detectors that perform well without any knowledge of the underlying channel models.

Detection Algorithms for Communication Systems Using Deep Learning

no code implementations22 May 2017 Nariman Farsad, Andrea Goldsmith

The design and analysis of communication systems typically rely on the development of mathematical models that describe the underlying communication channel, which dictates the relationship between the transmitted and the received signals.
