For Gionee M5, people are more concerned about its strong performance, the machine built 6020mAh capacity battery, one charge can be used for 4 days without recharging, and such products are also created a smart phone "power" record, and the machine has absolute strength in terms of endurance. In addition, the machine is also a support for all netcom 4G mobile phones, du
. Internet phones are increasingly integrated into enterprise applications to increase productivity and access information.
Small businesses have two main options for interest in VoIP: self-built or outsourced systems to hosted VoIP providers. In typical VoIP settings, enterprises purchase and manage their own VoIP devices and services. On the other hand, hosted voice providers run customers' Company voice, data, and Internet services on their own networks, place devices in their own data center

First look at the effect:
Create a new flash name casually, size 588*350:
1, the picture you want to put into the library inside.2, a new MC name for MC1, the picture just dragged in, on the alignment, left-aligned.3, a new MC name for color with a rectangular tool to drag a color bar width 20 high 350, and then back to mc1 a new layer, the color dragged in is left-aligned, on the alignmen
calculation.
The main reason is that this method does not reduce the number of multiplication of matrices. Matrix multiplication consumes much more time than matrix addition. So the breakthrough of the optimization algorithm is to reduce the multiplication operation . ~~~
According to the thought of the divide-and-conquer method, it can be seen that if we want to reduce the number of multiplication, the key is to calculate the product of 2 2-order matrices and use less than 8 times.

Evaluation Index:
1. Rank-n: The probability that the top (highest confidence) n graph in the search results has the correct result.
CMC Curve: Calculates a top-k hit probability, which is mainly used to evaluate the correct rate of rank in closed concentration.
For example: Lable is a m1 and is searched in 100 samples.
If the recognition results are M1, M2, M3, M4, M5 ..., the correct rate for rank-1 at this time is 100%;rank-2 and the correct rate
