过度拟合

Overfitting

在统计和机器学习中,当统计模型描述随机误差或噪声而不是基础关系时,发生过拟合。 过度拟合通常发生在模型过于复杂时,例如相对于观测次数的参数太多。 已经过度使用的模型通常会具有较差的预测性能,因为它可能会夸大数据的微小波动。 存在过度拟合的可能性,因为用于训练模型的标准与用于判断模型功效的标准不同。 特别地,模型通常通过在某些训练数据集上最大化其性能来训练。 然而,其功效不是由其在训练数据上的表现来确定,而是由于其对未知数据的表现良好的能力。 当模型开始记忆训练数据而不是学习从趋势推广出现过度拟合。 In statistics and machine learning, overfitting occurs when a statistical model describes random error or noise instead of the underlying relationship. Overfitting generally occurs when a model is excessively complex, such as having too many parameters relative to the number of observations. A model which has been overfit will generally have poor predictive performance, as it can exaggerate minor fluctuations in the data. The possibility of overfitting exists because the criterion used for training the model is not the same as the criterion used to judge the efficacy of a model. In particular, a model is typically trained by maximizing its performance on some set of training data. However, its efficacy is determined not by its performance on the training data but by its ability to perform well on unseen data. Overfitting occurs when a model begins to memorize training data rather than learning to generalize from trend.
