Summary of integration methods for machine learning models: Bagging, Boosting, Stacking, Voting, Blending
Article Introduction:Machine learning is a branch of artificial intelligence dedicated to building automatically learning and adaptive systems that use statistical models to visualize, analyze, and predict data. A general machine learning model consists of a data set (used to train the model) and an algorithm (learned from the data). But the accuracy of some models is often low and the results produced are less accurate. One of the simplest solutions to overcome this problem is to use ensemble learning on machine learning models. Ensemble learning is a meta-method that improves model performance by combining multiple machine learning models to produce an optimized model. Ensemble learning can easily reduce overfitting, preventing a model that performs better during training but fails to produce good results during testing. To sum up, ensemble learning has

学习总结(1):ssh 使用、Linux 目录结构与免密登录
Article Introduction:学习总结(1).:代表当前的目录,也可以使用./来表示;..:代表上一层目录,也可以../来代表。文章目录步骤0:ssh使用打开ssh工具putty(免费的!)后,登陆发觉报错Couldn'tagreeakeyexchangealgorithm,查了下说可能是putty版本太老了,就到官网上重新下载一个了——,神奇地好了(不过一开始以为帐号是ubuntu里面的那种帐号linux文件相关命令,始终没登上hhh,后来试了下才发觉是这坨东西的@前的东西哈哈哈哈)。另外也可以设置免密登陆,可以参考博客。

Machine learning classification problem: summary of nine commonly used evaluation indicators
Article Introduction:Evaluation metrics for machine learning are the core part of machine learning. This article summarizes commonly used evaluation indicators for classification problems. Evaluation Metrics for Classification ProblemsHere, various performance metrics that can be used to evaluate predictions for classification problems will be discussed. 1. Confusion Matrix This is the simplest way to measure the performance of classification problems where the output can be two or more types of classes. Confusion Matrix is nothing but a table with two dimensions i.e. "Actual" and "Predicted", furthermore both these dimensions have "True Positive (TP)", "True Negative (TN)", "False Positive ( FP)” and “False Negative (FN)” as follows: The terms related to the confusion matrix are explained as follows: True Positive (TP) − True when both the actual and predicted categories of the data point are 1

Learn the concurrent programming model in Go language and implement summary of distributed computing task results?
Article Introduction:Summary of task results for learning the concurrent programming model in Go language and implementing distributed computing. Go language is an efficient and concurrent programming language that is very powerful in handling concurrent tasks. By using the concurrency features provided by the Go language, we can easily build a distributed computing system, distribute computing tasks to multiple nodes, and summarize the calculation results of each node. First, we need to understand the concurrent programming model in Go language. The Go language implements concurrency through goroutines and channels. goroutine is
