Multistatic-Radar RCS-Signature Recognition of Aerial Vehicles: A Bayesian Fusion Approach

no code implementations28 Feb 2024 Michael Potter, Murat Akcakaya, Marius Necsoiu, Gunar Schirner, Deniz Erdogmus, Tales Imbiriba

To address this, we propose a fully Bayesian RATR framework employing Optimal Bayesian Fusion (OBF) to aggregate classification probability vectors from multiple radars.

Corticomorphic Hybrid CNN-SNN Architecture for EEG-based Low-footprint Low-latency Auditory Attention Detection

no code implementations13 Jul 2023 Richard Gall, Deniz Kocanaogullari, Murat Akcakaya, Deniz Erdogmus, Rajkumar Kubendran

In this paper, we propose a hybrid convolutional neural network-spiking neural network (CNN-SNN) corticomorphic architecture, inspired by the auditory cortex, which uses EEG data along with multi-speaker speech envelopes to successfully decode auditory attention with low latency down to 1 second, using only 8 EEG electrodes strategically placed close to the auditory cortex, at a significantly higher accuracy of 91. 03%, compared to the state-of-the-art.

EEG-based Texture Roughness Classification in Active Tactile Exploration with Invariant Representation Learning Networks

no code implementations17 Feb 2021 Ozan Ozdenizci, Safaa Eldeeb, Andac Demir, Deniz Erdogmus, Murat Akcakaya

Multiple cortical brain regions are known to be responsible for sensory recognition, perception and motor execution during sensorimotor processing.

Stopping Criterion Design for Recursive Bayesian Classification: Analysis and Decision Geometry

no code implementations30 Jul 2020 Aziz Kocanaogullari, Murat Akcakaya, Deniz Erdogmus

In this paper, we propose a geometric interpretation over the state posterior progression and accordingly we provide a point-by-point analysis over the disadvantages of using such conventional termination criteria.

Active recursive Bayesian inference using Rényi information measures

no code implementations7 Apr 2020 Yeganeh M. Marghi, Aziz Kocanaogullari, Murat Akcakaya, Deniz Erdogmus

The proposed active RBI framework is applied to the trajectory of the posterior changes in the probability simplex that provides a coordinated active querying and decision making with specified confidence.

Decoding Emotional Experience through Physiological Signal Processing

no code implementations1 Jun 2016 Maria S. Perez-Rosero, Behnaz Rezaei, Murat Akcakaya, Sarah Ostadabbas

Furthermore, in order to avoid information redundancy and the resultant over-fitting, a feature reduction method is proposed based on a correlation analysis to optimize the number of features required for training and validating each weak learner.

Asymptotic Analysis of Objectives based on Fisher Information in Active Learning

no code implementations27 May 2016 Jamshid Sourati, Murat Akcakaya, Todd K. Leen, Deniz Erdogmus, Jennifer G. Dy

In particular, we show that FIR can be asymptotically viewed as an upper bound of the expected variance of the log-likelihood ratio.
