These are the complete archived MATLAB codes of my Masters of Technology Thesis titled, "Data mining-based approach to study the effect of consumption of caffeinated coffee on the generation of the steady-state visual evoked potential signals". Please refer to the following articles to audit the complete work:

A few extra words on the creation of the dataset for the work in [1].

GLOSSARY
-------

SSVEP: Steady state visual evoked potentials (observed in EEG recordings with photic stimulus)

CCA: Canonical correlation analysis (https://youtu.be/rZoKH4fT-FE)

RQA: Recurrence quantification analysis

MLP: Multilayer perceptron network (ANN)

CAFFEINE: Data mining carried out with caffeinated and non-caffeinated SSVEP signals of 7 different frequencies.

-------

DATASET: 22 x 5120 x 6 x 7 (array)

22: Number of EEG channels
  
  5120: Number of sample points in each EEG channel
  
  6: Number of volunteers
  
  7: Number of differnt photic stimulus used to capture SSVEP signals
  
------

SSVEPs are a particular type of biosignal used in Rehabilitation Engineering for remote actuation of switches. The purpose of this study is to check the effects of caffeine consumption on these signals to verify an alternate hypothesis that, "Caffeine enhances the SSVEP activations". Indeed this hypothesis is found correct according to the results obtained from this present study where the signal enhancements are found mostly towards high-frequency SSVEP (greater than 30 Hz) signals.
