True positive (true, TP) is predicted as positive samples by the model; True negative (true negative, TN) is a negative sample predicted as negative by the model; False Positive (false positive, FP) is predicted as positive negative samples by the model; False Negative (false negative, FN) positive samples predicted as negative by the model; True positive rate (true rate, TPR) or sensitivity)TPR = TP/(TP + FN)Number of positive sample prediction results/actual number of positive samples True neg

1. If the file is being sent, we can click "Cancel" to be able to undo the file sent, but very small files almost 0 seconds on the hair, then how to withdraw it? 2. If a small file like the above has been sent, how do we recall the offline files that have been sent? 3. As shown in the following image if the other party does not accept the file we want to offline file next to have a small icon, we click on it will see a "

The accuracy rate, recall rate, and F value are important evaluation indicators of the target in a mixed environment. In this paper, these three indicators are favored. Let's take a look at the definition of these indicators first: Accuracy Rate = Total number of correctly recognized individuals/total number of identified individuals Recall rate = Total number of correctly recognized individuals/total nu

I. Overview: Nowadays, food safety problems are getting more and more serious, and consumers are increasingly uneasy about the products they have purchased. In this situation, the food safety traceability system is becoming more and more important, the State has also introduced mandatory policies to strengthen food safety supervision, implement national policies, implement electronic records of key links in product production, and trace the entire process of product production, quickly locate q

If we can develop some handy development tools at ordinary times, it will be like a huge addition. It will greatly improve our development efficiency. Visual Studio does not have to say that, through this article, you can recall other classic development tools and hope to introduce them to new users, I believe it will be of great help to the development on weekdays.

I have been working on. net programs since I started my work. I have not touched C ++ and mfc I learned myself for a long time. Today is a weekend break. I have read an MFC book and studied Serialize. On this trip, I once again admired the ingenuity of Microsoft Application Framework Team experts and created such an excellent Framwork for developers. People say, "posting is the best memories." I may also recall it here to record this "MFC serializati

Quick recall Regular Expression This is not an entry-level article, but if you have an understanding of regular expressions or have used them, it can help you quickly recall them. Reading this article requires you to have used regular expressions or some knowledge before, because I have not written many examples. To sum up regular expressions, I just want to give a brief overview of the symbols and usage in

Recall and precision I. query accuracy and precision are currently relatively reasonable indicators for measuring the search results.Query completion rate = (retrieved information volume/total amount of information in the system) * 100%Precision = (the amount of retrieved information/total amount of retrieved information) * 100%The former is to measure the ability of the retrieval system and the searcher to detect relevant information, and the latter

This log is indeed a trigger. I am not familiar with R, but it is required by the experiment, so I just learned it. We found that, whether it's countless tutorials on the Internet or examples in books, when talking about logistic regression, we will give a simple function and a description of the output results. I have never been clear about several things: 1. How to Use training data to train the model and then verify the test data (the test data and training data may overlap )? 2. How to calcu

From the test results of the target detection, always with false positve, precision rate, the recall rate of the several nouns. Always in the use of the time to clear the meaning of these words, but a long time, and to forget. A few days ago to discuss this issue with my brother, still vaguely, ambiguous. Decide to summarize it and write it down for a rainy future. The Chinese meanings of these three words are: false detection rate (also known as fal

The age threshold of an object's promotion to the old age can be set by parameter-xx:maxtenuringtbreshold.Dynamic O

there's going to be a company that wants me and keeps me? My answer is I'm afraid not!So I changed the old way of learning, and I had to change new ways of learning. That is the first to do their job, and then in the premise of doing a good job, to spend energy to learn other knowledge.I would also like to make 3 suggestions for my work:1, must find a better way to solve their own problems2, do not only understand the installation system, installed databases, do storage, do clusters, storage, t
