[Java nio] Channels, Buffers, and niobuffers
Channels and Buffers are two important concepts in java nio. NIO performs Data Operations Based on Channels and Buffers, and data is always read from Channels to Buffers, or written from Buffers to Channels.Channel)
You can write or read data from the channel;

I. What is IOCTL?IOCTL is a function used by the device driver to manage the device's I/O channels. The management of the I/O channel is to control some features of the device, such as the Serial Transmission baud rate and the motor speed. The number of calls is as follows:

In both CNN (1) and CNN (2) Two articles, the main explanation is CNN's basic architecture and weight sharing (Weight sharing), this article focuses on the convolution part.First, before convolution, our data is 4D tensor (width,height,channels,batch), which was mentioned in CNN (1): Architecture. The passage here, and the previously mentioned depth, is a concept, such as a grey scale image with a channel number of 1;RGB graphs of 3.In fact, Kernel al
On the interpretation of the channel:
1, the more understandable explanation is: gray-scale channel number of 1, color map of the channel is 3. Basically, the description of a pixel, if it is grayscale, then only need a number to describe it, is a single channel. If a pixel, there are RGB three colors to describe it, is three channels.

data records the amplitude, and the sampling accuracy depends on the size of the number of sampling digits:
1 byte (that is, 8 bit) can only record 256 numbers, that is, it can only divide the amplitude into 256 levels;
2 bytes (that is, 16 bit) can be subdivided into 65536 numbers, which is now the CD standard;
4 bytes (that is, 32 bit) can segment the amplitude to 4294967296 levels, which is unnecessary.
