ADRMX: Additive Disentanglement of Domain Features with Remix Loss

no code implementations12 Aug 2023 Berker Demirel, Erchan Aptoula, Huseyin Ozkan

To this end, most of existing studies focus on extracting domain invariant features across the available source domains in order to mitigate the effects of inter-domain distributional changes.

Source-Free Domain Adaptation for SSVEP-based Brain-Computer Interfaces

1 code implementation27 May 2023 Osman Berke Guney, Deniz Kucukahmetler, Huseyin Ozkan

This paper presents a source free domain adaptation method for steady-state visually evoked potentials (SSVEP) based brain-computer interface (BCI) spellers.

Transfer Learning of an Ensemble of DNNs for SSVEP BCI Spellers without User-Specific Training

1 code implementation3 Sep 2022 Osman Berke Guney, Huseyin Ozkan

We transfer this ensemble of fine-tuned DNNs to the new user instance, determine the k most representative DNNs according to the participants' statistical similarities to the new user, and predict the target character through a weighted combination of the ensemble predictions.

A Deep Neural Network for SSVEP-based Brain-Computer Interfaces

1 code implementation17 Nov 2020 Osman Berke Guney, Muhtasham Oblokulov, Huseyin Ozkan

Objective: Target identification in brain-computer interface (BCI) spellers refers to the electroencephalogram (EEG) classification for predicting the target character that the subject intends to spell.

A Neural Network Approach for Online Nonlinear Neyman-Pearson Classification

no code implementations14 Jun 2020 Basarbatu Can, Huseyin Ozkan

Our algorithm is appropriate for large scale data applications and provides a decent false positive rate controllability with real time processing since it only has O(N) computational and O(1) space complexity (N: number of data instances).

An Asymptotically Optimal Contextual Bandit Algorithm Using Hierarchical Structures

no code implementations5 Dec 2016 Mohammadreza Mohaghegh Neyshabouri, Kaan Gokcesu, Huseyin Ozkan, Suleyman S. Kozat

Therefore, we design our algorithms based on the optimal adaptive combination and asymptotically achieve the performance of the best mapping as well as the best arm selection policy.

Data Imputation through the Identification of Local Anomalies

no code implementations30 Sep 2014 Huseyin Ozkan, Ozgun S. Pelvan, Suleyman S. Kozat

We introduce a comprehensive and statistical framework in a model free setting for a complete treatment of localized data corruptions due to severe noise sources, e. g., an occluder in the case of a visual recording.
