VOC detector on the market 10000ppm 15000ppm 20000ppm TVOC Detector has so few, and we Hunan rike instrument unique, the accuracy of the first place.The biggest problem with such a large range VOC organic exhaust gas detector is how to ensure accuracy, because the sensor is not a linear one, and many instrument manufacturers in the market have made him linear, calibrating him with only one or two bottles of

First, prefaceThere are many indexes for characterizing classification accuracy, the most common one is the use of confusion matrix, the overall classification accuracy and kappa coefficients.The confusion matrix can clearly see the number of correct classification of each figure and the category and number of the wrong points. However, the confusion matrix can not see the quality of classification

Dataset The data set Pga.csv of this article contains the service statistics for professional golfers, including two attributes: accuracy and distance. Accuracy accuracy describes the ratio of hit lanes (fairways hits), distances describes the average distance of the tee. Our goal is to use distance to predict the hit rate. In golf, the farther a person

This article is mainly on the JavaScript to avoid the accuracy of digital calculation method is introduced, the need for friends can come to the reference, I hope to help you.What if I ask you 0.1 + 0.2 equals a few? You may give me a supercilious eye, 0.1 + 0.2 = 0.3 Ah, do you still ask? Even the children in kindergarten will answer such a question of pediatrics. But you know, the same problem is in the programming language, perhaps not as simple as

First, the plot to measure the data to change the accuracy For example, we draw a right triangle as shown in the following figure, by measuring the height of the triangle, now the accuracy is 1%, then how to operate, the realization of accuracy is 1 per thousand? The following steps are: Geometry artboard Step one Select the "Move Arrow tool" On th

For more information about the speed and accuracy of the mouse-Linux general technology-Linux technology and application, see the following. Let's talk about my previous usage habits (I believe many people are the same as me). In XP, the mouse speed is the fastest, "Improving pointer accuracy" is not open (this is actually the mouse speed, I thought it was just to move the mouse at the same distance at diff
