通过训练资料(包含输入和预期输出的数据集)去学习或者建立一个函数模型,并依此模型推测新的实例。函数的输出可以是一个连续的值(回归问题,Regression),或是预测一个分类标签(分类问题,Classification)。 机器学习中与之对应还有: 无监督学习(Unsupervised Learning) 强化学习(Reinforcement Learning) 在课程中定义了一些符...

Linear Regression Is Sensitive to Outliers Outliers are data that are surprising. Outliers can be univariate (based on one variable) or multivariate. If you are looking at age and income, univariate outliers would be things like a person who is 118 years old, or one who made $12 million la...

We briefly outline the interpretation of such coefficients and show through an example from a recently published study how arbitrary choices about the scaling or coding of variables prior to analysis can produce coefficients and hypothesis tests for so-called "main effects" that have different and ...
This method is often used to simplify data interpretation. Standardization transformations include square root, cube root and logit transformation. Probabilistic Transformation (smoothing) modify the shape of the distribution. For example, if a dataset is normally distributed before the transformation, it ...
