好的,有了.csv数据我们可以使用Pandas库来读取数据,然后将数据分为训练集和测试集,最后使用灰狼优化算法来训练模型并进行预测。具体实现步骤如下:
1. 导入必要的库,并读取.csv数据
```python
import pandas as pd
import numpy as np
import pygwo
df = pd.read_csv('data.csv')
```
2. 对数据进行预处理,将输入特征和输出结果分开
```python
X = df.drop(['舒适度'], axis=1).to_numpy()
y = df['舒适度'].to_numpy()
# 划分训练集和测试集
train_size = int(0.8 * len(X))
X_train, X_test = X[:train_size], X[train_size:]
y_train, y_test = y[:train_size], y[train_size:]
```
3. 定义舒适度预测函数,该函数以输入参数为参数,返回舒适度预测值。
```python
def predict_comfort(area, orientation, sunshine, outdoor_max_temp, outdoor_min_temp, indoor_temp, indoor_people):
# 此处为模型的具体实现,省略
return comfort
```
4. 定义适应度函数,该函数以灰狼个体为参数,返回该个体的适应度值,即舒适度预测值。
```python
def fitness_function(wolf):
area = wolf[0]
orientation = wolf[1]
sunshine = wolf[2]
outdoor_max_temp = wolf[3]
outdoor_min_temp = wolf[4]
indoor_temp = wolf[5]
indoor_people = wolf[6]
comfort = predict_comfort(area, orientation, sunshine, outdoor_max_temp, outdoor_min_temp, indoor_temp, indoor_people)
return comfort
```
5. 定义灰狼优化算法的参数和初始种群。
```python
lower_bounds = [0, 0, 0, -10, -10, 0, 0]
upper_bounds = [1000, 360, 24, 50, -30, 30, 100]
problem_size = len(lower_bounds)
population_size = 30
max_iterations = 100
initial_population = pygwo.GWO.get_initial_population(problem_size, population_size, lower_bounds, upper_bounds)
```
6. 创建灰狼优化算法对象并运行算法。
```python
gwo = pygwo.GWO(fitness_function, lower_bounds, upper_bounds, problem_size, population_size, initial_population)
best_wolf, best_fitness = gwo.run(max_iterations)
```
在运行完毕后,`best_wolf`即为最佳的灰狼个体,`best_fitness`即为对应的舒适度预测值。您可以根据需要修改参数和函数实现细节。
