监督式学习 Supervised learning

(重定向自Supervised classification)

监督式学习英语:Supervised learning),是一个机器学习中的方法,可以由训练数据中学到或创建一个模式(函数 / learning model),并依此模式推测新的实例。训练数据是由输入对象(通常是矢量)和预期输出所组成。函数的输出可以是一个连续的值(称为回归分析),或是预测一个分类标签(称作分类)。

一个监督式学习者的任务在观察完一些训练范例(输入和预期输出)后,去预测这个函数对任何可能出现的输入的值的输出。要达到此目的,学习者必须以"合理"(见归纳偏向)的方式从现有的数据中一般化到非观察到的情况。在人类和动物感知中,则通常被称为概念学习(concept learning)。

Supervised learning 监督式学习

(重定向自Supervised classification)

Supervised learning is the machine learning task of inferring a function from labeled training data. The training data consist of a set of training examples. In supervised learning, each example is a pair consisting of an input object (typically a vector) and a desired output value (also called the supervisory signal). A supervised learning algorithm analyzes the training data and produces an inferred function, which can be used for mapping new examples. An optimal scenario will allow for the algorithm to correctly determine the class labels for unseen instances. This requires the learning algorithm to generalize from the training data to unseen situations in a "reasonable" way (see inductive bias).
