Course objectives
The aim of the course is to familiarize students with the basic biological signals, their specifics, processing, analysis and ways to display the processed results. For the analysis of real EEG and ECG data, Mathematica environment will be used.
Syllabus
  • Resources, specifics, general principles and diagnostic use of digital signal processing. Overview of methods and algorithms of signal processing. EEG, EMG, ECG, EOG. Real time and offline processing, statistical characteristics, stochastic processes, time series analysis, nonstationarity.
    Acquisition and pre-processing of biological data. Digitization, sampling and quantization, aliasing. Filtration. Trends.
    Spectral analysis. Basic methods. Periodogram, autoregressive model. Parametric and nonparametric methods. Estimation of the spectrum, cross spectrum, coherence, phase. Fast Fourier Transform (FFT), its importance and applications. Displaying using compressed spectral arrays (CSA). EEG - local and interhemispheric coherence. Topographic mapping of electrophysiological activity. Brain mapping. Amplitude and frequency mapping. Use in clinical diagnostics. Dynamic mapping.
    Adaptive segmentation. Motivation. Nonstationary biosignals. Basic methods. Multi-channel on-line adaptive segmentation. Feature extraction.
    Methods for automatic classification. Unsupervised learning, metrics, data normalization. Clustering, K-means algorithm. Fuzzy sets. Optimizing the number of classes. Neural networks. Hebb learning. Multi-channel signals. Self-organizing method of principal components. Learning classifiers. Supervised vs. unsupervizované learning. On-line classification. k-NN classifier (classical, fuzzy). Comparison with neural networks.
    Automatic detection of epileptic graphoelements. Automatic detector of spikes, arithmetic detector, combined detector. Principal components and conventional filtering for detection. ECG signal, the digital processing, features. Criteria for ECG digitization, frequency analysis and filtering, adaptive filtering. Data reduction, Holter identification techniques.

The course can also be completed outside the examination period.
Teacher's information
Credit: elaboration of semester project on a given topic of at least 4 and a maximum of 20 pages of text. Topics will be assigned during the semester list of selected topics suggested by teachers is available on the website (see section contents). Students can design their own theme and have them approve the teacher. We welcome topics the processing of which actively contributes to the student's skills and acquired knowledge. Examination: oral only, consisting of one of the clinical questions and one question on the monitoring. In case of an extremely successful semestral project it can be (after successful discussion with the student) recognized as equivalent to passing the exam and graded A.
