Cosine Similarity

We have developed a metric to measure how similar a person's brainwaves are to those of healthy individuals. This measurement evaluates how similar two vector values are in hyper-space and plays a significant role in Machine Learning and Artificial Intelligence. According to this metric, the EEG data of individuals who have used Auto Train Brain for 3, 6, and 9 months gradually resemble the EEG data of normal individuals over time.
