Figure 1: Training the model from sklearn.linear_model import LinearRegression regressor = LinearRegression() regressor.fit(X_train, y_train) 完成后,我们就训练好了我们的模型,现在可以进行预测了,如图 2 所示。 Figure 2: Making predictions 在Java 中使用 ML 模型 我们现在需要做的是把 ML 模型转换...
5 Scikit-learn 描述: Scikit-learn 是基于 NumPy, SciPy 和 Matplotlib 的 Python 机器学习库。它包含了许多用于数据挖掘和数据分析的工具,包括回归、分类、聚类、降维等。 示例: 使用 scikit-learn 训练一个简单的线性回归模型。 from sklearn.linear_model import LinearRegression import numpy as np x = np....
1.1文件导入:常见的文件格式包括CSV、Excel和JSON。使用Python的pandas库,可以方便地读取这些文件。例如,使用pd.read_csv()函数可以快速将CSV文件加载为DataFrame对象。 1.2数据库连接:许多数据存储在数据库中,Python支持连接多种数据库,如MySQL和SQLite。通过使用SQLAlchemy库,用户可以轻松地从数据库中提取数据。 import ...
