个人医疗开支预测项目

注意：本文引用自专业人工智能社区Venus AI

项目背景

随着医疗成本的持续上涨，个人医疗开支成为一个重要议题。理解影响医疗费用的多种因素对于医疗保险公司、政府机构以及个人都至关重要。利用数据分析和机器学习技术，我们能够更好地预测和管理个人医疗费用。

项目目标

本项目的主要目标是开发一个能够准确预测个人医疗费用的模型。通过分析影响医疗费用的各种因素，如年龄、性别、BMI、吸烟状态、居住地区等，我们希望提供给保险公司和政策制定者更深入的见解，以便他们制定更有效的策略和计划。

项目应用

保险定价: 帮助保险公司基于客户的个人健康数据定制保险费率。
政策制定: 为政府和医疗机构提供数据支持，以便制定更有效的医疗保健政策。
个人医疗规划: 辅助个人基于他们的健康状况和生活方式来规划未来的医疗费用。

数据集（描述到特征）

数据集包含以下特征：

年龄(age): 主要受益人的年龄。
性别(sex): 保险合同者的性别，包括女性和男性。
BMI(bmi): 身体质量指数，衡量体重与身高的关系，理想范围是18.5至24.9。
子女数量(children): 受健康保险覆盖的子女数量。
吸烟状况(smoker): 是否吸烟。
居住地区(region): 受益人在美国的居住地区，包括东北部、东南部、西南部和西北部。
医疗费用(charges): 由健康保险账单的个人医疗费用。

模型和依赖库

项目中使用了多种模型和依赖库：

模型:
1. 线性回归模型(Linear Regression Model)
2. 随机森林回归模型(Random Forest Regression Model)
3. 带有GridSearchCV的支持向量回归模型(Support Vector Regression Model with GridSearchCV)
4. 梯度提升模型(GradientBoost Model)
5. 简单的密集神经网络(Simple Dense Neural Network)
依赖库:

使用 5 个不同模型进行建模实验

# 定义特征和标签
X = df2.drop('charges' ,axis=1)
y = df2['charges']

# 进行训练和测试分离
from sklearn.model_selection import train_test_split
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)

len(X_train) ,len(y_test)

(1070, 268)

# 进行一些预处理
from sklearn.preprocessing import StandardScaler
scaler = StandardScaler()scaled_X_train = scaler.fit_transform(X_train)
scaled_X_test = scaler.transform(X_test)

模型1：线性回归

from sklearn.linear_model import LinearRegression
lr = LinearRegression()
lr.fit(scaled_X_train ,y_train)

LinearRegression

LinearRegression()

# 检查性能
from sklearn.metrics import mean_squared_error ,r2_score
lr.score(scaled_X_test ,y_test)

0.7835929767120722

r2_score(y_test ,lr.predict(scaled_X_test))

0.7835929767120722

模型 2：随机森林模型

from sklearn.ensemble import RandomForestRegressor

rf = RandomForestRegressor(n_estimators = 140,criterion = 'squared_error',random_state = 42,n_jobs = -1)rf.fit(scaled_X_train,y_train)

RandomForestRegressor

RandomForestRegressor(n_estimators=140, n_jobs=-1, random_state=42)

forest_test_pred = rf.predict(scaled_X_test)

r2_score(y_pred = forest_test_pred ,y_true = y_test)

0.8650776528213561

所以分数从 0.78 提高到 0.87

模型 3：带有 GridSearchCV 的支持向量机

from sklearn.svm import SVR
from sklearn.model_selection import GridSearchCV

svr = SVR()

# 定义 gridsearchcv 的参数网格
param_grid = {'C':[0.001,0.01,0.1,0.5,1],'kernel':['linear','rbf','poly'],'gamma':['scale','auto'],'degree':[2,3,4],'epsilon':[0,0.01,0.1,0.5,1,2]}

grid = GridSearchCV(svr,param_grid=param_grid)

grid.fit(scaled_X_train,y_train)

# 检查最佳参数
grid.best_params_

{'C': 1, 'degree': 2, 'epsilon': 2, 'gamma': 'scale', 'kernel': 'linear'}

grid_preds = grid.predict(scaled_X_test)

r2_score(y_true = y_test ,y_pred=grid_preds)

0.019799220771840598

SVR 模型的性能非常差。猜测是出现了严重的过拟合

模型 4：GradientBoost 模型

from sklearn.ensemble import GradientBoostingRegressor

gb = GradientBoostingRegressor(random_state = 42)

gb.fit(scaled_X_train ,y_train)

GradientBoostingRegressor

GradientBoostingRegressor(random_state=42)

gb_preds = gb.predict(scaled_X_test)

r2_score(y_true = y_test ,y_pred = gb_preds)

0.8792571359795264

所以我们使用梯度提升模型得到了 0.88 的分数，这比之前的分数要高。

模型 5：密集神经网络

import tensorflow as tf

scaled_X_train.shape

(1070, 8)

import tensorflow as tf# Set the random seed for reproducibility
tf.random.set_seed(42)# Define the model
model = tf.keras.Sequential([tf.keras.layers.Dense(32, activation='relu'),  # First hidden layer with 32 neurons and ReLU activationtf.keras.layers.Dense(1)  # Output layer with 1 neuron (for regression)
])# Compile the model
model.compile(loss=tf.keras.losses.MeanAbsoluteError(),  # Using Mean Absolute Error for lossoptimizer=tf.keras.optimizers.Adam(learning_rate=0.1),  # Adam optimizer with a learning rate of 0.1metrics=['mae']  # Tracking Mean Absolute Error as a metric
)# Train the model
model.fit(scaled_X_train,y_train,epochs=500,validation_data=(scaled_X_test, y_test)
)
