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

If Keil arm is used, vpbdiv = 0x00000000 is automatically generated in startup. S, which leads to fpclk dividing by 4. The baud rate is reduced by four times. The default value of startup. s in Keil is as follows .; // ; // ; // ; // ; // ; // ; // ; // ; // ; // ; // Vpbdiv_setup equ 0vpbdiv_val equ 0x00000000 we will change it: Vpbdiv_setup equ 1 Vpbdiv_val equ 0x00000001 Solve the problem. # Include # Include "config. H" # Define uart_bau

and the intersection of the Ground Truth, which is the accuracy rate of the detection:Iou=detectionresult⋂groundtruthdetectionresult⋃groundtruth IoU = \frac{detectionresult⋂groundtruth} { Detectionresult⋃groundtruth} As shown in the following illustration:The blue box is: GroundtruthThe Yellow box is: DetectionresultThe green box is: Detectionresult⋂groundtruthThe red box is: Detectionresult⋃groundtruth to say. 1, this article refers to the followin

Methods for finding the circumference rate π and the circumference rate π Method 1: Calculate the approximate value of π by probability method. The probability method is also called the Monte Carlo method. Suppose there is a circle with a radius of 1, then the area of the 1/4 circle is equal to 1/4 π. The probability method is used to calculate the area of 1/4 circles, and 1/4 π is obtained. The specific pr

Data Sequential frame storage First, record the left and right channels of frame 1, and then start the record of Frame 2... [Non-staggered mode] The first record is the left-channel sample of all frames within a cycle, and then all right-channel samples are recorded. Bit Rate] Trans

This article describes how to use the yahoo Exchange Rate Interface to implement real-time exchange rate conversion. For more information, see the following code: Function getExchangeRate ($ from_Currency, $ to_Currency) {$ amount = urlencode ($ amount); $ from_Currency = urlencode ($ from_Currency); $ to_Currency = urlencode ($ scheme ); $ url = "download.finance.yahoo.com/d/quotes.html?

Recall (recall rate); Precision (accuracy rate); F1-meature (Comprehensive evaluation index); These parameters are often used in information retrieval (such as search engines), natural language processing, and detection classifications.Precision: The percentage of information that is detected that is correct or relevant ( that is, what you want)(Number of positive samples predicted as a proportion of the to

　　What is the use rate of PF? Pf:page file, pagefile (virtual memory) PF Usage: value of the amount of space that virtual memory has already used 　　What is the reason for the high utilization rate of PF Although PF is called virtual memory, it will still occupy a lot of space when it is too large, and it will have a great impact on the speed of the computer when the PF usage is too high. The reasons fo

Python method for calculating pi of circumference rate, python pi of circumference Rate The example in this article describes how to calculate the circumference pi of python. Share it with you for your reference. The details are as follows: from sys import stdout scale = 10000 maxarr = 2800 arrinit = 2000 carry = 0 arr = [arrinit] * (maxarr + 1) for i in xrange(maxarr, 1, -14): total = 0 for j in xrange

Configure the specified access rate and distributed access rate policy. You can use the rate-limit port to configure the command. remove the ratelimit configuration and add no to the original command. command: rate-limit {input | output} [access-group [rate-limit] acl-index]

can use to transfer data, Thus, the higher the speed can be achieved, in addition to this, we can improve the signal quality and eliminate the bottleneck effect. Higher transmission speeds. The proportional relationship between network bandwidth and data transmission capability was first made by Bell Labs engineer Claude. Shannon found, so this law is also known as Shannon law. On the popular side, the number of networks The "network bandwidth" is exactly the same as the "network bandwidth", an

In short, bounce rate can reflect the user satisfaction with your website from a perspective. The satisfaction level is inversely related to the bounce rate of the website. That is, the higher the website bounce rate, the lower the user satisfaction and the lower the website bounce rate, the higher the user satisfactio
