机器学习算法在学习过程中对某种假设(hypothesis)的偏好,称为“归纳偏好”(inductive bias),或简称为“偏好”。

所谓的inductive bias,指的是人类对世界的先验知识,对应在网络中就是网络结构。

下面是一些inductive bias的例子:

Algorithm | Inductive Bias

Linear Regression | The relationship between the attributes x and the output y is linear. The goal is to minimize the sum of squared errors.

Single-Unit Perceptron | Each input votes independently toward the final classification (interactions between inputs are not possible).

Neural Networks with Backpropagation | Smooth interpolation between data points.

K-Nearest Neighbors | The classification of an instance x will be most similar to the classification of other instances that are nearby in Euclidean distance.

Support Vector Machines | Distinct classes tend to be separated by wide margins.

Naive Bayes | Each input depends only on the output class or label; the inputs are independent from each other.
