Asthma in children has a long duration and is prone to recurring attacks. Children will feel chest tightness, shortness of breath, cough, and difficulty breathing when they are onset, which has a serious impact on their health. Clinical nursing is of great significance in the treatment of childhood asthma. At present, the electronic health PDCA nursing model is widely used in clinical nursing as a common and effective nursing method. Therefore, it is very important to evaluate the efficacy of the PDCA nursing model in the treatment of childhood asthma. With the development of artificial intelligence, artificial intelligence can be used to evaluate the effect of the PDCA nursing model in the treatment of childhood asthma. The BP network can effectively perform data training and discrimination, but its training efficiency is low, and it is easily affected by initial weights and thresholds. Aiming at this defect, this work uses the genetic simulated annealing (GSA) algorithm to improve it. In view of the problems that the genetic algorithm falls into local minimum and simulated annealing algorithm has a slow convergence speed, the improved genetic simulated annealing algorithm is used to optimize the BP neural network, and an improved genetic simulated annealing BP network (IGSA-BP) is proposed. The algorithm not only reduces the problem that the BP network has an influence on initial weight and threshold on the algorithm but also improves the population diversity and avoids falling into local optimum by improving the crossover and mutation probability formula and improving Metropolis criterion. The proposed method has more efficient performance.
儿童哮喘病程长,容易反复发作。儿童发病时会感到胸闷、呼吸急促、咳嗽、呼吸困难,对其健康危害极大。临床护理在儿童哮喘的治疗中具有重要意义。目前,电子健康 PDCA 护理模式作为一种常见而有效的护理方法,已广泛应用于临床护理中。因此,评价 PDCA 护理模式在儿童哮喘治疗中的疗效非常重要。随着人工智能的发展,人工智能可用于评估 PDCA 护理模式在儿童哮喘治疗中的效果。BP 神经网络可以有效地进行数据训练和判别,但训练效率低,易受初始权重和阈值的影响。针对这一缺陷,本工作采用遗传模拟退火(GSA)算法对其进行改进。针对遗传算法容易陷入局部最小值和模拟退火算法收敛速度慢的问题,利用改进的遗传模拟退火算法对 BP 神经网络进行优化,提出了一种改进的遗传模拟退火 BP 网络(IGSA-BP)。该算法不仅减少了 BP 网络对算法初始权重和阈值的影响问题,而且通过改进交叉和变异概率公式,提高了Metropolis 准则,提高了种群多样性,避免了陷入局部最优。提出的方法具有更高效的性能。
