Project assignment

All the tasks below should be applied to the following dataset.

The project should be reported in a concise but high standard research-like article.

The report should be returned by the 15th of January.

Characterisation of the frequency content

• Specify the frequency content of the data using Fourier analysis.
• Filter out the 60 Hz power line and the base-line wander.
• Extend the analysis into time-frequency representation both in Fourier and Wavelet bases. Justify your choice of Wavelet basis. Explain the reasons for the differences between the two approaches.

Segmentation

• alpha
• beta
• delta

Modelling and time-series prediction

• Find a good balance between model complexity (the number of time lags) and predictive power.
• Check for stationarity in the data by computing the innovation process (i.e. the residual between the data and the prediction of the model)
• Predict 10 next values for the data.
