Supervised Learning In supervised learning, we are given a data set and already know what our correct output should look like, having the idea that there is a relationship between the input and the output. Supervised learning problems are categorized…

Machine Learning is a class of algorithms which is data-driven, i.e. unlike "normal" algorithms it is the data that "tells" what the "good answer" is. Example: an hypothetical non-machine learning algorithm for face recogniti…

Predictive learning vs. representation learning  预测学习 与 表示学习 When you take a machine learning class, there's a good chance it's divided into a unit on supervised learning and a unit on unsupervised learning. We certainly care about this distinction f…

监督学习即是supervised learning,原始数据中有每个数据有自己的数据结构同时有标签,用于classify,机器learn的是判定规则,通过已成熟的数据training model达到判断新点类型的目的. 非监督学习即是unsupervised learning,原始数据中没有附加标签,仅有数据结构,cluster的过程是机器发现相似数据结构先去找相似pattern,没有新加入的数据,仅是对原始数据的描述.  …
