Autodecompose: A generative self-supervised model for semantic decomposition

1 code implementation6 Feb 2023 Mohammad Reza Bonyadi

We introduce Autodecompose, a novel self-supervised generative model that decomposes data into two semantically independent properties: the desired property, which captures a specific aspect of the data (e. g. the voice in an audio signal), and the context property, which aggregates all other information (e. g. the content of the audio signal), without any labels given.

Self Punishment and Reward Backfill for Deep Q-Learning

1 code implementation10 Apr 2020 Mohammad Reza Bonyadi, Rui Wang, Maryam Ziaei

We prove that, under certain assumptions and regardless of the reinforcement learning algorithm used, these two strategies maintain the order of policies in the space of all possible policies in terms of their total reward, and, by extension, maintain the optimal policy.

Semi-supervised Seizure Prediction with Generative Adversarial Networks

no code implementations20 Jun 2018 Nhan Duy Truong, Levin Kuhlmann, Mohammad Reza Bonyadi, Omid Kavehei

In this article, we propose an approach that can make use of not only labeled EEG signals but also the unlabeled ones which is more accessible.

A theoretical guideline for designing an effective adaptive particle swarm

no code implementations13 Feb 2018 Mohammad Reza Bonyadi

We relate these assumptions to the movement patterns of particles controlled by coefficient values (inertia weight and acceleration coefficient) and introduce three factors, namely the autocorrelation of the particle positions, the average movement distance of the particle in each iteration, and the focus of the search, that describe these movement patterns.

Linear centralization classifier

A Generalised Seizure Prediction with Convolutional Neural Networks for Intracranial and Scalp Electroencephalogram Data Analysis

no code implementations6 Jul 2017 Nhan Duy Truong, Anh Duy Nguyen, Levin Kuhlmann, Mohammad Reza Bonyadi, Jiawei Yang, Omid Kavehei

The proposed approach achieves sensitivity of 81. 4%, 81. 2%, 82. 3% and false prediction rate (FPR) of 0. 06/h, 0. 16/h, 0. 22/h on Freiburg Hospital intracranial EEG (iEEG) dataset, Children's Hospital of Boston-MIT scalp EEG (sEEG) dataset, and Kaggle American Epilepsy Society Seizure Prediction Challenge's dataset, respectively.

Optimization of distributions differences for classification

no code implementations2 Mar 2017 Mohammad Reza Bonyadi, Quang M. Tieng, David C. Reutens

Our results show that the method is less sensitive to the imbalanced number of instances comparing to these methods.

Supervised Learning in Automatic Channel Selection for Epileptic Seizure Detection

no code implementations31 Jan 2017 Nhan Truong, Levin Kuhlmann, Mohammad Reza Bonyadi, Jiawei Yang, Andrew Faulks, Omid Kavehei

We present a novel method for automatic seizure detection based on iEEG data that outperforms current state-of-the-art seizure detection methods in terms of computational efficiency while maintaining the accuracy.
