Early Detection of Alzheimer’s Disease by Blind Source Separation and Bump Modeling of EEG Signals
نویسندگان
چکیده
The early detection Alzheimer’s disease is an important challenge. Using blind source separation, wavelet time-frequency transforms and “bump modeling” of electro-encephalographic (EEG) recordings, a set of features describing the recordings of mildly impaired patients and of controls subject is built. Feature selection by the random probe method leads to the selection of a few reliable features, which are fed to a neural network classifier. This leads to a sizeable performance improvement over detection results previously published on the same data.

The early detection Alzheimer’s disease (AD) is an important challenge. In this paper, we propose a novel method for early detection of AD using electroencephalographic (EEG) recordings: first a blind source separation algorithm is applied to extract the most significant spatio-temporal components; these components are subsequently wavelet transformed; the resulting timefrequency representation...

The early detection of Alzheimer’s disease (AD) is an important challenge. In this paper, we propose a novel method for early detection of AD using only electroencephalographic (EEG) recordings for patients with Mild Cognitive Impairment (MCI) without any clinical symptoms of the disease who later developed AD. In our method, first a blind source separation algorithm is applied to extract the m...
