Objective Machine learning is divided into: supervised learning, unsupervised learning, semi-supervised learning (can also be used Hinton said reinforcement learning) and so on. Here, the main understanding of supervision and unsu

=b0+y1=1So the linear model isBecause we use the function interval to measure whether it is correctly classified, that is, the linear model is preceded by the parameter Yi because the correct classification time yi=1, the wrong classification of the time Yi=-1, so can be the product of the two as long as more than 0 can represent the correct classification, do not need to update the function parameters. Less than or equal to 0 indicates that the

effective prediction (people think, since it is not possible to get more, first look at what is in hand, then data mining appeared).Machine learning methods are very much, but also very mature. I'll pick a few to say.The first is SVM. Because I do more text processing, so more familiar with SVM. SVM is also called Support vector machine, which maps data into mul

Original: Image classification in 5 Methodshttps://medium.com/towards-data-science/image-classification-in-5-methods-83742aeb3645 Image classification, as the name suggests, is an input image, output to the image content classification of the problem. It is the core of computer vision, which is widely used in practice. The traditional method of image classification is feature description and detection, such traditional methods may be effective for some simple image classification, but the tradit

So the basic elements that a machine learning should normally include are: training data, model with parameters, loss function, training algorithm training The data function is needless to say; the m

We will first perform linear regression on the data, that is, the first graph on the left. If we do this, we can obtain such a straight line that fits the data, but in fact this is not a good model. Let's look at the data. Obviously, as the area of the house increases, the changes in the housing price tend to be stable, or the more you move to the right

We will learn how to systematically improve machine learning algorithms, tell you when the algorithm is not doing well, and describe how to ' debug ' your learning algorithms and improve their performance "best practices". To optimize machine learning algorithms, you need to
