AR (autoregressive) model (Autoregressive model): To predict the present or future performance of a variable by the performance of the same variable, which is related only to the variable itself and not to other variables, so called autoregressive.
Mathematical definition Model: Assuming that AR model is P-order, for a set of time series have observed value {x[1]
When there are frequently used modules in our program and such modules are also used in other programs, we should generate libraries based on the idea of software reuse, so that later programming can reduce the amount of development code. Here we will introduce the two commands AR and Nm for database operations.
1. Basic ar usage

Recently, it has been reported that the poor yield of TSMC 10nm chip may have a greater impact on the launch of more than 2017 high-end mobile devices, including, naturally, the next generation of IPhone and IPAD models. However, TSMC formally dismissed the claim, suggesting that the 10 nano-processor production was done exactly as planned, without any lag, and that the processor would start to profit in the first quarter of next year.TSMC also released another blockbuster message. TSMC also sai
This article mainly introduces the CI framework AR operation to insert Multiple SQL data records, and analyzes the CI framework using arrays to insert multiple data records in the form of a simple example, for more information about how to insert Multiple SQL data records, see the example in this article. We will share this with you for your reference. The detail
In this paper, the method of inserting multiple SQL data into a CI framework ar operation is described. Share to everyone for your reference, specific as follows:
If you don't use AR, you can do this:
INSERT into TABLE (FIELDS) VALUES (' 1 ', ' 2 '), (' 3 ', ' 4 ');
$this->db->query ($sql);

A piece of news I saw online in Zhongguancun, I think the one I used in NRC is similar to this one, but the name is different. Ar has been paying attention to it for a long time. It seems to be a promising technology, especially in the convenience of entertainment games. It can be used as a good way to connect virtual reality with reality.
In the end, I cannot help but feel that these new things are all on

Three elements of AR applications:
1. Video Source)
Video sources primarily provide frames collected from built-in cameras.
2. processing pipeline (MPS Queue)
The processing pipeline mainly provides a simple interface to the program, which encapsulates the underlying data structure and algorithm.
