EEG Based Eye State Classification using Deep Belief Network and Stacked AutoEncoder

Abstract

<p>A Brain-Computer Interface (BCI) provides an alternative communication interface between the human brain and a computer. The Electroencephalogram (EEG) signals are acquired, processed and machine learning algorithms are further applied to extract useful information. During EEG acquisition, artifacts are induced due to involuntary eye movements or eye blink, casting adverse effects on system performance. The aim of this research is to predict eye states from EEG signals using Deep learning architectures and present improved classifier models. Recent studies reflect that Deep Neural Networks are trending state of the art Machine learning approaches. Therefore, the current work presents the implementation of Deep Belief Network (DBN) and Stacked AutoEncoders (SAE) as Classifiers with encouraging performance accuracy. One of the designed SAE models outperforms the performance of DBN and the models presented in existing research by an impressive error rate of 1.1% on the test set bearing accuracy of 98.9%. The findings in this study, may provide a contribution towards the state of the art performance on the problem of EEG based eye state classification.</p>

Bio-signals compression using auto-encoder

“…Usually the condition monitoring is trained in three steps, namely feature extraction (FE) from raw data, feature selection (FS) of the most relevant features and fault classification using machine learning. FE and FS thereby represent a gradual data dimensionality reduction that is necessary to prevent the classifier to suffer from overfitting and the "curse of dimensionality" [2], which makes machine learning ineffective, if the number of features is high. Thus, high feature quality is the precondition for good prediction results.…”

“…The main aim of this paper is sensing the human's behavior [1] via IoT device that is wearable like chest straps, smart watches, wristbands, etc. that can be utilized to point-out the specific health and the required fitness of the clients [2]. Wearable devices can be combined into body sensor networks that are wirelessly connected to bring reports of the medical up-to-date though internet.…”

Improved feature exctraction process to detect seizure using CHBMIT-dataset

“…Some of the previous paper we got to know that feature extraction was not performed, they have used deep learning models with trained raw EEG signals [5][6][7]. From last few years, machine learning and data learning entered into the computer vision.…”

Improve of contrast-distorted image quality assessment based on convolutional neural networks

“…Artificial neural networks has been the most popular tools for machine learning [4], which in more general sense for deep learning. Among several deep learning architectures, stacked denoising autoencoders [5], deep belief networks [6][7], and convolutional neural networks [8][9][10][11][12][13] are three of the most popular architectures utilized for different type of applications. Convolutional neural networks (CNNs) are a special kind of deep learning method, CNNs run much faster on GPUs, such as NVidia's Tesla K80 processor, and has achieved state of the art performance on various computer vision tasks, such as object detection, recognition, retrieval, annotation, image classification, and segmentation [14][15][16].…”
