Train a logistic regression classifierPython Kopiraj from sklearn.linear_model import LogisticRegression with mlflow.start_run() as run: lr_id = run.info.run_id print(f"run_id {lr_id}, status: {run.info.status}") lr = LogisticRegression(random_state=42) lr.fit(X_train_res, y_...
Step 4: Train and evaluate the modelWith the data in place, define the model. In this section, you train a logistic regression model to classify the vectorized text.Prepare training and test datasetsPython Copy # Split the dataset into training and testing (train_df, test_df) = vec_df....
至少10行代码 model.fit(X_train, y_train) 描述: 在这一部分中,逻辑回归模型被选为分类算法。使用LogisticRegression类创建模型实例,并设置最大迭代次数为1000,以确保模型有足够的时间收敛。然后,使用训练集(X_train和y_train)对模型进行拟合,使其学习特征与标签之间的关系。 5. 预测与评估 from sklearn....

Data analysts and database developers are familiar with SQL. Unfortunately, you often have to learn a new programming language (such as Python or R) to build, train, and deploy ML models in SageMaker. When the model is deployed and you want to use...
