Part I: ClassificationThe first two parts of the book focus on supervised Learning (supervisedieaming). In the process of supervising learning, we only need to give the input sample set , and the machine can push the possible results of the specified target variable from it. Supervised learning is relatively simple, an
and theories, especially for those who do engineering applications, the real need for mathematical knowledge mediocre, mainly include: calculus, linear algebra, probability theory, optimization methodLet's take a look at the following:CalculusFirst of all, Calculus/advanced mathematics. In machine learning, calculus is mainly used in the differential part, the f
values of each eigenvalue have the same scale range, so that the influence of each eigenvalue is the same.How do I set the value of λ? By selecting a different λ to repeat the test process, a λ that minimizes the prediction error is obtained. The best value can be obtained by cross-validation-the sum of squared errors is minimized on the test data.Ridge regression was first used to deal with more than a sample number of features, and is now used to add human bias to the estimate, thus obtaining
these friends are connected to you ). From the above example, we can see that machine learning is actually a imitation of human intelligence and the only way to achieve human and higher intelligence.

actually nearly 20000 citations, really scary. It is not surprising to think carefully, all kinds of research work, as long as the classification, most will use the SVM algorithm or with SVM algorithm comparison, and at this time LIBSVM is often the preferred tool. In fact, not only the academia, LIBSVM in the industrial sector also has a very wide range of applications. This is due to the stability and efficiency of the algorithm implementation, on the other hand because LIBSVM provides a rich

There is a need to note that we will eventually choose to perform the best model on the CV set, but the final evaluation of this model is to be in a new data d_test (similar to the Netflix Prize competition, The official eventually gives your model a rating of data) on the test. Andrew NG recommends dividing the data as follows:

implementation for multi-label learning and evaluation methods. In multi-label classification, we need to predict multiple output variables for each input instance. This is different from the "normal" case where only one single target variable is involved. In addition, MEKA's WEKA-based machine learning toolkit.

machine learning algorithms use advanced optimization algorithms. Do not try to re-implement these methods unless this is what you intend to do with this project. You should use a class library that provides an optimization algorithm, or an optimization algorithm (such as a gradient descent algorithm) that is easier to implement or that has simple points in the
process statistics, analyze and visualize data. Through various examples, the reader can learn the core algorithm of machine learning, and can apply it to some strategic tasks, such as classification, prediction, recommendation. In addition, they can be used to implement some of the more advanced features, such as summarization and simplification. I've seen a pa
