4.具体代码实例和详细解释说明
在本节中,我们将通过一个具体的代码实例来展示Dataiku Data Science Studio的应用。这个代码实例是一个简单的线性回归模型,用于预测房价。
首先,我们需要导入数据:
import pandas as pd
data = pd.read_csv('house_prices.csv')
接着,我们需要进行数据清洗和预处理:
data['bedrooms'] = data['bedrooms'].fillna(data['bedrooms'].mean())
data['bathrooms'] = data['bathrooms'].fillna(data['bathrooms'].mean())
data['sqft_living'] = data['sqft_living'].fillna(data['sqft_living'].mean())
data['sqft_lot'] = data['sqft_lot'].fillna(data['sqft_lot'].mean())
然后,我们需要进行数据探索:
data.describe()
接着,我们需要进行特征缩放:
from sklearn.preprocessing import StandardScaler
scaler = StandardScaler()
data[['bedrooms', 'bathrooms', 'sqft_living', 'sqft_lot']] = scaler.fit_transform(data[['bedrooms', 'bathrooms', 'sqft_living', 'sqft_lot']])
接着,我们需要将数据分为训练集和测试集:
from sklearn.model_selection import train_test_split
X = data[['bedrooms', 'bathrooms', 'sqft_living', 'sqft_lot']]
y = data['price']
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)
接着,我们需要构建线性回归模型:
from sklearn.linear_model import LinearRegression
model = LinearRegression()
model.fit(X_train, y_train)
接着,我们需要评估模型:
from sklearn.metrics import mean_squared_error
y_pred = model.predict(X_test)
mse = mean_squared_error(y_test, y_pred)
print('MSE:', mse)
最后,我们需要部署模型:
from flask import Flask, request
app = Flask(__name__)
@app.route('/predict', methods=['POST'])
def predict():
data = request.get_json(force=True)
prediction = model.predict([[data['bedrooms'], data['bathrooms'], data['sqft_living'], data['sqft_lot']]])
return {'price': prediction[0]}
if __name__ == '__main__':
app.run(debug=True)
