Particle swarm optimization algorithm (PSO) is a random search with the global qualitative group evolution algo?rithm,, robust, through the particle swarm optimization algorithm with the combination of BP algorithm, BP algorithm to solve slow convergence speed, easy to fall into local minimum problem, and experiment PSOBP algorithm its convergence perfor?mance, learning speed and stability is superior to BP algorithm. Combined with the actual demand to Indian liver disease as an ex?ample to PSOBP algorithm in the application of medicine were discussed.
