machine learning algorithm -PCA dimensionality reduction OneIntroductionThe problems we encounter in the actual data analysis problem usually have the characteristics of higher dimensionality, when we carry out the actual data analysis, we will not use all the features for the training of the algorithm, but rather pick out the features that we think may affect the target. For example, in the Titanic Crew survival prediction problem, we will use the na

Speaking of Java, people first think of Java programming language. However, Java is actually a technology, which consists of four aspects: java programming language, Java file format, Java Virtual Machine and Java application interface (Java API ). Shows the relationship between them: Figure 1 Relationship between four aspects of Java The runtime environment represents the Java platform. Developers compile

do you want to download bad apps, because you have distractions in mind. If you are a pure user, may not choose other channels to download the application, will go to the regular market download applications, so you can not be engaged, if you are a heart without distractions of users, will not arbitrarily authorized to the application, will not choose the root device. So the reason is that the illegal molecule is using a small number of people's mind, produced this sample to start extortion. An

processes, and finally the results are combined output. Note that the learning process here is independent of each other.There are two types of aggregations:1) After the fact: combine solutions that already exist.2) before the fact: build the solution that will be combined.For the first scenario, for the regression equation, suppose there is now a hypothetical set: H1,H2, ... HT, then:The selection principle of weight A is to minimize the errors in the aggregation hypothesis set.For the second

calculates the accuracy of the entire system at this time: As shown in, text recognition consists of four parts. Now we can find the system accuracy after optimization for each part. The question is, how can we improve the accuracy of the entire system? We can see from the table that, if we have optimized the text moderation part, the accuracy will be72%Add89%If we optimize the character segmentation, the accuracy is only from89%To90%If character recognition is optimized90%To100%In contr
