本博文是对How to Evaluate Machine Learning Models这一博文的一个简单翻译和总结,文章主要从Evaluation Metrics ,Testing Mechanisms,Hyperparameter Tuning和A/B testing四个角度对机器学习模型的评价做了一一分析和讨论,建议有能力的人直接看原PO文。 1.评价指标(Evaluation Metrics ) 1.1 Classification metrics 假设...
并且一般短期指标并不与长期指标保持一致。 在机器学习过程中,一般会用到四种类型的评价指标,分别是:训练评价指标(training metrics)、离线评价指标(验证评价指标,offline evaluation metrics or validation metrics)、新生数据评价指标(live metrics)、商业指标(business metrics)。训练评价指标是指模型优化的评价指...

For supervised machine learning models, this approach enables you to compare the labels predicted by the model to the actual labels in the validation dataset. By comparing the predictions to the true label values, you can calculate a range of evaluation metrics to quantify the predictive ...
Model Evaluation There are different metrics for the tasks of classification, regression, ranking, clustering, topic modeling.无法输入公式,传图片～Use the training data to train several candidate models.Use the cross-validation data to pick the best of these models, based on F1 Score, for example...
机器学习的过程(The Machine Learning Process) 第一步是训练模型(the process of passing training data to a model so that it can learn to identify patterns in data) 测试模型在验证集上的效果,This is known as modelevaluation。这一步可能会重复多次,因为模型的架构会变更,使用的特征也会变更,一旦对于模...
