在这类问题中,我们可以利用目标变量调整模型,属于监督学习(Supervised Learning)范畴。由于目标变量是连续的,是一个典型的回归(Regression)问题。监督学习的框架如下图所示:设计学习算法,再用训练集进行训练,最后得到一个反映输入变量和目标变量之间映射关系的模型,利用该模型可以预测出测试数据的目标变量。 在监督学习中,我们有mm个训练样本组成的训练

Supervised Learning (Regression) In supervised learning, the task is to infer hidden structure from labeled data, comprised of training examples $(\{(x_n, y_n)\})$. Regression typically means the output $(y)$ takes continuous values. We demonstrate with an example in Edward. An interactive...
