, people may have skin color, height, physique and ... Hey, I'm evil. And so on, are these features independent of each other? Of course not, such as the black average height is not white high, there are black people running ability and so on, characteristics and characteristics are related. But naive Bayesian sees them as independent. In principle, naive Bayes has an objective minimum error rate because it requires the least number of parameters. But

AI Bacteria Perceptron is one of the oldest classification methods, and today it seems that its classification model is not strong in generalization at most, but its principle is worth studying. Because the study of the Perceptron model, can be developed into support vector machine (by simply modifying the loss function), and can develop into a neural network (by simply stacking), so it also has a certain position. So here's a brief introduction to

there is no prior knowledge, the Gaussian kernel is generally chosen. Why choose a Gaussian nucleus? Because you can map data to an infinite-dimensional space.Minimum optimization of the SMO sequenceThis learning method is to simply solve the parameters of the SVM algorithm, is not very important (change-^-^), so there is no very detailed look, later have time to read and then update to this article.Pending Update:Reference books:The method of statis

first, gradient descent method In the machine learning algorithm, for many supervised learning models, the loss function of the original model needs to be constructed, then the loss function is optimized by the optimization algorithm in order to find the optimal parameter. In the optimization algorithm of machine

Course Description: This is an introductory course on deep learning, and deep learning is mainly used for machine translation, image recognition, games, image generation and more. The course also has two very interesting practical

Here we are now learning to sell. A typical example of discriminant analysis is linear discriminant analysis (Linear discriminant analyses), referred to as LDA. (notice here not to be confused with the implied Dirichlet distribution (latent Dirichlet allocation), although

algorithm, neural network based algorithm and so on. Of course, the scope of machine learning is very large, and some algorithms are difficult to classify into a certain category. For some classifications, the same classification algorithm can be used for different types of problems. Here, we try to classify commonly used algorithms in the easiest way to underst

formed a more perfect experience accumulation of the application scene. There are many applications in data mining that need to be developed, even if it is possible to dig out valuable patterns. Like Recommender systems, computer vision, and NLP, these values are known to be more fortunate than others. Write the Book of course everything to write, is there something in machine

the file name of the data to iris.csv. The Code is as follows: 1 Is it easy? Just 12 lines of code is enough. Next, let's test it. According to the figure above, when we input 5 3.3 1.4 0.2, the output should be Iris-setosa. Let's take a look: Check that at least one original data is input and the correct result is obtained. But what if we enter data that is not in the original dataset? Let's test two groups: From the data of the two images we posted earlier, the data we input does not exist
