ML is known because of its execution through its diverse learning approaches. These approaches are known as supervised, unsupervised, and reinforcement. These are performed only on data, as its quintessential element. In Supervised, attempts are done to find the relationship between the independent ...
2. Supervised Learning Supervised learningis a technique consisting of providing labeled data to a machine learning model. The labeled dataset is usually data gathered from experience, also called empirical data. In addition, the data often requires preparation to increase its quality, fill its gaps...
A Brief Introduction to Weakly Supervised Learning 在监督学习中,一个训练样本包含两个部分:特征向量(feature vector或instance)、标签(label); 本文重点关注三种弱监督方式:不完全监督(incomplete supervision)、不确切监督(inexact supervision)、不准确监督(inaccurate supervision); 还存在其他类型的无监督学习,比如延时...
Graph-Based Semi-Supervised Learning Assumption:如果两个instances被strong edge相连,那么他们的标签趋于一致。 未归一化的laplacian矩阵L有下列性质: 1、 L 有l+u 个特征值(一些可能相同)和相对应的特征向量 (){(λi,ϕi)}i=1l+u ,这些对叫作图谱(graph spectrum)。特征向量是正交的: ,ϕiTϕj=0...
active learning: 有人为干预,假设可以query to get ground-truth of selected unlabeled instances semi-supervised learning: 无人为干预,企图从unlabeled data中自动提取一些信息 active learning: semi-supervised learning: 知乎上有一篇写得很好的总结:https://zhuanlan.zhihu.com/p/32922326 ...
有两种主要的技术能够实现此目的,即主动学*(active learning)【2】和半监督学*(semi-supervised learning)【3-5】。 主动学*假设有一个「神谕」(oracle),比如人类专家,可以向它查询所选未标注数据的真值标签。相比之下,半监督学*试图在没有人为干预的前提下,自动利用已标注数据、以及未标注数据来提升学*性能。

All learning algorithms are explained so that the student can easily move from the equations in the book to a computer program.The text covers such topics as supervised learning, Bayesian decision theory, parametric methods, multivariate methods, multilayer perceptrons, local models, hidden Markov ...
1.1. Types of Supervised Machine Learning Supervised learning has been divided into two categories, Regression:Regressionis used to forecast a continuous value. For example, estimating the cost of a house depending on its size, location, and number of rooms. ...
