selected.As the evaluator you need to evaluate (evaluation) under his work First we can calculate the accuracy rate (accuracy), which is defined as: for a given test data set, the classifier correctly classifies the ratio of the number of samples to the total number of samples. That is, the loss function is a 0-1 loss when the accuracy rate on the test data set [1].This sounds a bit abstract, simply p

How to judge if optimization is good or not? How to identify if the optimization is in place? Today I come to talk about my website optimization experience, in my opinion, site optimization is not only to see a site rankings and traffic, but should focus on the core of optimization, why do we want to optimize the site? Because we need to improve the conversion rate of the website, So is your site optimized to now improve the conversion

Editor's note: This article from the United States famous red dot venture Tom tunguz Hand, by a number of well-known overseas science and technology Media and VC Media reprinted, Chinese version by Heaven Zhuhai Branch Rudder compiled. How do you calculate the user churn rate for your own startups? How many users are lost per month? That can't hold the key, because there are big customers and small customers. By the upward sales

The serial port of 51 chips can work in several different working modes. The working mode is set to use the scon register. The specific definitions of its bits are as follows:Sm0 SM1 SM2 Ren tb8 rb8 Ti riSm0 and SM1 are bits in the working mode of the serial port, so that the two can be set in four modes. Set the working mode of the serial port. When using the serial port for communication, a very important parameter is the baud rate. normal communic

Site bounce rate is when users visit your site, then only browse a page after the proportion of left, the site bounce rate is a measure of user behavior is very important an indicator, he can tell you whether the user is interested in this page or site, of course, to analyze a page jump rate can not be a stick to kill, High bounce

Qiniu Seven cow problem solutionnoun Introduction1, the code rate: "Bit rate" is the distortion, the higher the rate of the clearer, the other is the picture rough and more mosaic. "Bit rate" is the number of bits per second that are transmitted. The unit is bps (bit per Second), the higher the bitrate, the faster the

characters. Communication is done using 3 wires: (1) ground, (2) sent, (3) received. Because the serial communication is asynchronous, the port can send data on one line and receive data on the other line at the same time. Other lines are used to shake hands, but are not required. The most important parameters of serial communication are baud rate, data bit, stop bit, and parity check. For two ports to pass, these parameters must match:baud rateThis

Phrases like "unsustainable memory allocation rate" and "you need to maintain a low memory allocation rate" look like a proprietary term for Java champions (Java Champions). Complex, scary, and full of mysterious colors.These words often appear, but if you dig deeper into these concepts, the mystery of it disappears. This article will try to uncover the mysteries of these terms.What is the memory allocation

Resolve the calculation of the bandwidth and port rate of the vswitch backboard. When using the bandwidth of the vswitch backboard, problems such as the bandwidth of the vswitch backboard frequently occur, as well as the bandwidth of the vswitch with line speed and related knowledge, here we will introduce the solutions to many problems related to the vswitch backboard bandwidth. We all know that the unit of the total data exchange capability of the v

The conversion rate indicator is widely used in data analysis across all walks of life. For example, it exists in e-commerce and click a series of conversion rates generated by orders, the traditional sales industry will also consider how many orders the advertisement can convert when it advertises. In the gaming industry, the conversion rate is also an indicator that cannot be ignored. In general, the gam
