The dataset contains images of the 2D topograms of EEG power distributed over the head. It includes anonymized data of 20 subjects, each subject's data are collected in a separate folder. The filename of each image is structured as "ambiguity_cluster_trial.png". "Ambiguity" takes the value of "HA" if the topogram characterizes processing of the stimuli with high ambiguity, or "LA" if the stimulus ambiguity is low. "Cluster" takes the values "1,2,3" depending on the cluster number. Each cluster reflects the time-frequency range where we average EEG power to plot the topogram. "Trial" takes the values "1...100". Each trial corresponds to a single stimulus processing.
