Traditionally epileptic seizure prediction is realized with a visual examination of Electroencephalogram (EEG) signals. But this technique needs a long time EEG monitoring. So, the automatic epileptic seizures prediction schemes become a requirement at this point. This study proposes a method to classify epileptic seizures and normal EEG data by utilizing the Intrinsic Time-scale Decomposition (ITD)-based features. The dataset has been supplied from the database of the Epileptology Department of Bonn University. It contains 5 data groups A, B, C, D, E. The study aims to classify healthy and epileptic data, so data of groups A and E are used to perform evaluations of proposed methods. The EEG data are decomposed into Proper Rotation Components (PRCs) by ITD. The feature extraction methods are applied to the first five PRCs of each EEG data from healthy and epileptic individuals. These features are classified using K-Nearest Neighbors (KNN), Linear Discriminant Analysis (LDA), Naive Bayes, Support Vector Machine (SVM) and Logistic Regression classifiers. The results demonstrated that the epileptic data is differentiated from normal data by applying the nonlinear ITD with outstanding classification performance.","PeriodicalId":426945,"journal":{"name":"2020 Medical Technologies Congress (TIPTEKNO)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116178382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Examples of these areas are image recognition, face detection, natural language processing, toxicology, suggestion systems, anomaly detection and disease diagnosis in the health sector. This study focuses on studies on disease prediction and diagnosis through histopathological images. The main purpose of the study is to apply deep learning models that can classify cancerous tissues with high accuracy. Besides that, implementation of deep models are done with a low computational cost so that models can be trained in a fast manner. Within the scope of this subject, the convolutional neural network models, which are very popular in image classification in the deep learning world, have been realized by applying transfer learning technique. In addition to these models, a deep learning model called CAT-Net is used to compare and evaluate the success of the transfer learning method.

It is mostly used in the diagnosis of sleep respiratory disorders also PSG test can be used in the diagnosis of diseases such as sleep terror, restless leg syndrome, sleep paralysis and narcolepsy. The patient, who is subjected to the PSG test, spends the night in a sleep laboratory under the supervision of a specialist physician and technician. The PSG test is very expensive and there are a limited number of PSG devices and a limited number of sleep technicians for this test in sleep centers. Even if an attempt is made to prepare an environment close to the home, the sleep test performed in a laboratory environment cast out the patient from the natural sleep environment. For these reasons and more, devices have been manufactured to reduce the cost of tests, perform the test in the sleep environment that the patient is accustomed to, and serve more patients at home. In this study, an Iot based, wearable test device was developed that allows patients with sleep disorders to perform sleep tests at home, at lower costs, without the need for a sleep technician.","PeriodicalId":426945,"journal":{"name":"2020 Medical Technologies Congress (TIPTEKNO)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133458723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The electroencephalography (EEG) recording method is the most frequently used clinical practice in the diagnosis and monitoring of epilepsy. Many computer-aided analysis methods have been developed in the literature to facilitate the analysis of long-term EEG signals. In the proposed study, the patient-based seizure detection approach is proposed using a high-resolution time-frequency (TF) representation named Synchrosqueezed Transform (SST) method. The SST of two different data sets called the IKCU data set and CHB-MIT data set are obtained, and Higher-order joint TF(HOJ-TF) based and Gray-level co-occurrence matrix (GLCM) based features are calculated using these SSTs. Using some machine learning methods such as Decision Tree (DT), k-Nearest Neighbor (kNN), and Logistic Regression (LR), classification processes are conducted.

Atrophy values obtained by magnetic resonance imaging (MRI), one of the neuroimaging techniques, are considered to be a fairly powerful diagnostic biomarker used in the detection of Alzheimer. Since the transition from early mild cognitive impairment (EMCI) to late mild cognitive impairment (LMCI) is irreversible and implies a significant change in a patient’s condition, we focus on to the classification of these two stages in this work. In this study, atrophy values of 13 brain areas of 90 early mild cognitive impairment, 38 late mild cognitive impairment, 14 mild cognitive impairment participants were used in the diagnosis of the disease. Diagnosis groups have been classified with an accuracy of 68.8% as a result of data estimations obtained using classification algorithms. When the classification has been made only by taking effective values, an accuracy rate of 75% has been achieved and this means a significative improvement. The deep analysis of the disease and the focusing on the brain regions where it has more impact in order to distinguish the stages early, show the potential of utilizing MRI features to improve cognitive assessment.","PeriodicalId":426945,"journal":{"name":"2020 Medical Technologies Congress (TIPTEKNO)","volume":"168 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122029923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
