The classification of a machine learning system is usually based on the manner in which the system is trained and the manner in which the system can make predictions. Machine learning systems are classified as
Data collectionin machine learning refers to the process of collecting data from various sources for the purpose to develop machine learning models. This is the initial step in the machine learning pipeline. To train properly, machine learning algorithms require huge datasets. Data might come from a...
This is called the bias/variance dilemma and is true for any machine learning system and not only for polynomial regression。为了减少bias,模型要变得更灵活,但是会导致更加高的variance。如果方差小,可能无法好的拟合数据有更高的bias。最优的模型是trade-off的。 如果有bias,说明模型没有包含solution,这是...
In last chapter, we've talked about the generative and discrminant model, these two are for classification or regression. And the basic underlying both are densities estimation. Once we can obtain the p(\mathbf{x}) ( we use p(\mathbf{x}) here for show that we are describe a random ...
Introduction to Machine Learning 机器学习(Machine Learning)最早起源于人工智能(Artificial Intelligence,AI),其核心在于构造学习算法(Learning Algorithm),使得机器可以自动从训练数据中进行学习以完成特定任务。 机器学习的定义 1959年,Arthur Samuel将机器学习定义为:"Field of study that gives computers the ability ...
