What is sound? Energy Wave, with frequency and amplitude, the frequency level is the tone, the amplitude size is the volume, the sampling rate is the frequency sampling, and the sampling accuracy is the amplitude sampling The frequency range that people can hear is 200-20 kHz, What is codec? Audio Compression Co + extract Dec, codec is a multimedia digital signal decoder, mainly responsible for DAC and ADC. Whether the audio accelerator is

1 need to obtain the system precise clock function:1) for the general real-time control, the use of GetTickCount () function can meet the accuracy requirements, but to further improve the timing accuracy, it is necessary to use the QueryPerformanceFrequency () function and QueryPerformanceCounter ( function2) These two functions are high-precision time functions provided by the VC for Windows 9X only, and r

In order to better evaluate the performance of IR system, IR has a complete evaluation system, through which the evaluation system can understand the merits and demerits of different information systems, the characteristics of different retrieval models, the influence of different factors on information retrieval, and further optimize the information retrieval.Since the objective of IR is to return more comprehensive and accurate information in a relatively short period of time, the evaluation i

Accuracy test (result accuracy testing)For example, Assert.assertequals (expected, actual).If the result does not meet the expectations, it produces failure. Indicates a problem with the program logic.Failure test (throwing exception tests)The expected property is used to indicate the type of exception expected to be thrown. For example, @Test (expected = illegalargumentexception.class).If the result does n

following statement: ./examples/cifar10/train_quick.shAfter that, the CIFAR10 dataset will begin training, after the training is complete, look under the Caffe/examples/cifar10/log folder, Will find that there is more than one caffe.cat.dog.log.info.20170508-141812.7610 file, where cat and dog are training system name and user name, of course, the time is dynamically generated. This is our training system log, in order for it to generate the error curve we need, we need to make some changes to

I just almost let this idea suffer.The rest is not much to say,Code that pos

IEEE 754 specification, using double-precision storage (double precision), occupying a single bit.Significance 1 bits used to denote symbol bits 11 bits to represent the exponent 52-bit indicates mantissa Floating-point numbers, such as0.1 >> 0.0001 1001 1001 1001 ...

When it comes to maintaining an older financial project, we find that the calculation of precision is simple and rough, first look at the code snippet:if ($accountInfo [' Account_money '] As shown in the code fragment variable above, the above code mainly compares account balances and repayments, both double-precision floating-point numbers, slightly modified code, so that we can see some of the output is more intuitiveif ($accountInfo [' Account_money '] Run as above code get as resultTwo numbe

Programmers have problems often need to search, sometimes, because the description of the problem is unclear, it often takes a long time to find the answer. There are all kinds of naming when programming, if not accurate, will let a person be confused, cannot understand.Therefore, we need to strengthen the accuracy of the use of words and the mastery of professional terminology.Talk about professional nouns It's normal for you to feel strange
