Brain wave medical record signal reduction method based on three-layer cross game energy trees

The invention discloses a brain wave medical record signal reduction method based on three-layer cross game energy trees, the brain wave medical record signal reduction method includes designing two adjacent three-layer cross game trees Ti and Tj, realizing self game in a same main layer and cross coordinated game among different main layers, and adopting a depth-first search strategy to select global optimization elites Elitisti-c and Elitistj-c; distributing elite energy gain matrix PMENnxn to optimal elite, and enhancing performance, on acquiring self-adaptive Nash energy exploration and development balance, of elite on the main layers; realizing cross game energy reduction of brain wave medical record signals, and enabling the optimal elite driven by elite energy vector Gamma to converge to optimal Nash balance points of each main layer to realize brain wave medical record signal reduction accuracy balance so as to output global optimal brain wave medical record signals. By the brain wave medical record signal reduction method, brain wave medical record signal reduction efficiency can be improved effectively, and an important method is provided for brain wave noise elimination and feature extraction and analysis; the brain wave medical record signal reduction method has high application value in brain disease diagnosis and adjuvant therapy.
