Supervised learning is a machine learning technique in which an algorithm learns from a set of labeled data to make predictions or classify new, unseen data. The classification task in supervised learning involves assigning a category or class label to input data based on the available training exa...
So far in this course, you have developed a linear model that predictsfw,b(x(i))fw,b(x(i)): fw,b(x(i))=wx(i)+b(1)(1)fw,b(x(i))=wx(i)+b In linear regression, you utilize input training data to fit the parametersww,bbby minimizing a measure of the error between our p...

Support Vector Machine,这个我特地查了一下中文,叫做“支持向量学习机”,翻译得非常直白。这是一个supervised learning model,一般用于classification或者regression。这里我们主要讲classification的情况。SVM的中心思想就是寻找一根hyperplane来把两个不同class分开来。理论上来说,我们可以找到无数跟这样的hyperplane,所以我们...
Supervised Learning: Classification 在本章中,我们将重点关注实施有监督的学习 - 分类。 分类技术或模型试图从观察值中得出一些结论。 在分类问题中,我们有分类输出,如“黑色”或“白色”或“教学”和“非教学”。 在构建分类模型时,我们需要具有包含数据点和相应标签的训练数据集。 例如,如果我们想检查图像是否是...
Self-Supervised Learning,又称为自监督学习,我们知道一般机器学习分为有监督学习,无监督学习和强化学习。 而 Self-Supervised Learning 是无监督学习里面的一种,主要是希望能够学习到一种通用的特征表达用于下游任务 (Downstream Tasks)。 其主要的方式就是通过自己监督自己。作为代表作的 kaiming 的 MoCo 引发一波热议...

Covers four different supervised learning methods in R, with the purpose of classification, that is, assigning observations (data) to an outcome class. Examples of datasets covered in exercises are: road signs, credit applicants, potential charity donors, smartphone location data. ...
Finally, a supervised learning classifier named Attention-fused Residual Convolutional Neural Network (ANR-CNN) is proposed. Here, the combination of channel and spatial attention mechanisms captures important features in the feature map in both channel and spatial dimensions. The convolutional residual ...
