(i) Recognition of the returnRegression is one of the most powerful tools in statistics. Machine learning supervised learning algorithm is divided into classification algorithm and regression algorithm, in fact, according to the category label distribution type is discrete, continuity and defined. As the name implies, the classification algorithm is used for disc
Course Description:This is the last lesson of the course, the author first summed up the theory, methods, models, paradigms, and so on machine learning. Finally, the application of Bayesian theory and Aggregation (aggregation) method in machine
, and we get the right result. However, do we enter data that is not in the original data set? Let's test two groups:From the data of the two graphs we posted earlier, the data we entered does not exist in the dataset, but the classification is reasonable according to our initial observations.So, this machine learning library is enough for most people. And most despise this library despise that library, tal
, the use of very convenient, greatly reduced the application of machine learning threshold. Of course, the shortcomings are obvious, because of the UDF programming interface provided by the database, the implementation of the algorithm will be subject to a lot of constraints, many optimizations difficult to achieve, and large-scale data sets of

million points to find an optimal hyper-plane, where there are 100 supporting vectors, then I just need to remember the information of these 100 points, and for subsequent classifications it is only necessary to use these 100 points instead of all 1 million points for calculation. Of course, in addition to the "memory-based learning" algorithm such as K-nearest neighbor, usually the algorithm does not dire
in the first section, the meta-algorithm briefly describesIn the case of rare cases, the hospital organizes a group of experts to conduct clinical consultations to analyze the case to determine the outcome. As with the panel's clinical consultations, it is often better to summarize a large number of individual opinions than a person's decision. Machine learning also absorbed the ' Three Stooges top Zhuge Li
randomly groups the data to the extent that training intensive accounts for 70% of the original data (this ratio can vary depending on the situation), and the test error is used as the criterion when selecting the model. The question comes from the Stanford University Machine Learning course on Coursera, which is described as follows: the size and price of the
I. Introduction of supervised learningThe supervised machine learning problem is nothing more than "Minimizeyour error while regularizing your parameters", which is to minimize errors while the parameters are being parameterized. The minimization error is to let our model fit our training data, and the rule parameter is to prevent our model from overfitting our training data. What a minimalist philosophy! B

name. However, this is a standard term that people use in machine learning, so we don't have to worry about why people call it. Summary: when solving the housing price prediction problem, we actually want to "Feed" the training set to our learning algorithm, and then learn a hypothesis H, then we input the size of the house we want to predict into H as t
