Duematernity.com is an online mother and child retail project, with a 27% increase in the 360° mapping conversion rate. In the past, their websites used traditional two-dimensional images, such as a woman in a maternity outfit, to stand in front of one another.
Add 360° rotation to the picture, when the shopper browses the Product Details page, the picture is rotated automatically, on these pages the selling product conversion rate is higher than the standard two-dimensional picture 27%.

The following is a brief list of common recommended system metrics:
1. Accuracy rate and Recall rate (Precision Recall)
Accuracy and recall rates are two measures widely used in the field of information retrieval and statistical classification to evaluate the quality of the results. The accuracy is to retrieve the number of related documents and the total number of documents retrieved, to measure the precision of the retrieval system; Recall is t
faster data rate (10MHZ) and a wider bus (bits). Called Fast/wide, SCSI-2 allowed data transfer rates up to MB/s with backward compatibility and SCSI-1, albeit at the SCSI-1 data rate.
The development of SCSI-3 began in 1993 and is actually a collection of standards defining, protocols, command sets, and Si Gnaling methods. Under the moniker SCSI-3, you'll find a collection of parallel SCSI standards with the name Ultra and modern serial ased protoc

CPU usage is usually split into four categories:
System: Processor Time spent executing system or OS kernel-level activity
User: Processor time spent performing user activity
I/O wait: The processor time spent waiting to complete an I/O request in idle state
Idle: Alluding to no processor activity
The other two related indicators are the running queue Length (that is, pending matters for requests waiting for CPU time) and context transformations (the conv
ArbitragePOJ-2240
Arbitrage is the use of discrepancies in currency exchange rates to transform one unit of a currency into more than one UN It's the same currency. For example, suppose that 1 US Dollar buys 0.5 British pound, 1 British pound buys 10.0 French francs, and 1 French franc Buys 0.21 US dollar. Then, by converting currencies, a clever trader can start with 1 US dollar and buy 0.5 * 10.0 * 0.21 = 1.05 US dollars, MA King a profit of 5 perce
require and the final slope of the final fitting line.Thus, the problem of gradient descent concentrates on the rotation of the tangent. When the tangent rotates to horizontal, the tangent slope = 0, the error drops to the minimum value.
The magnitude of each rotation of the tangent is called the learning rate (learning rates), and increasing the learning rate will speed up the fitting speed, but if the adjustment is too large it causes the tangent
Data analysis is inseparable from the tracking of key indicators, indicators are a measure of the quality of an index. There are many data indicators, however, not all the indicators are good, the vanity indicator (Vanity Metrics) looks beautiful, makes you feel good, but such indicators are superficial, and even fraudulent, for example, you will focus on the site's traffic, but ignore the jump rate, the user's browsing time, etc. It's easy for you to fall into the trap of vanity indicators.

In a Cisco switch, how does one configure QOS speed limit? How to restrict BT download? This blog will use detailed examples for your explanation.
Instance 1: QOS speed limit problem on CISCO switches
It is used to control the bandwidth of a leased line user on a vswitch. The vswitch is usually at 10/100/1000 or three rates. QOS is required for other rates. You can also limit some ports, policy to restrict

Latency indicators have a great impact on real-time sensitive applications, such as network phones, video conferencing, and database replication. Therefore, good latency indicators are very important for evaluating firewall performance.
Latency tests for all frame lengths are performed at 50% and 100% throughput rates. The latency results of storage forward
specifies the number of BITs compressed by the audio file. When you use a low bit rate, you will lose the sound quality.
You should select different bit rates based on the specific audio files, and try to use different bit rates to compare which one is the most suitable, weigh the sound file size and sound quality. If most of your files are speech data, you can use a relatively low bit rate.

Avi itself only provides such a framework. The internal image data and audio shun data formats can be any encoding format. Because the index is placed at the end of the file, it cannot be used to play Internet streaming media. In a simple example, it is difficult to play a video downloaded from the Internet if it is not completed. Another problem is that Avi does not support high-bit-rate VBR audio files.
The full name of VBR is variable bitrate, which is the dynamic bit rate.

In addition, some IGMP functions can be used to support multicast, but only serve as multicast users and cannot serve as multicast servers.3.
