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)
