Figure 3. Electrode placement diagram-Classification of Human Emotion from Deap EEG Signal Using Hybrid Improved Neural Networks with Cuckoo Search

<p>Reference electrode placed AFz placed in between AF1 and AF2 electrode and ground<br> electrode Oz is placed between O1 and O2 electrodes. The impedance of the electrode range is<br> 5K&Omega;. The sampling rate was fixed range between 256 samples per second for all the channels.<br> Figure 3 shown in below which is represent the electrode placement diagram. The recorded EEG<br> signal is used to recognize the different level of emotions.</p>
