Caffe is reproduced on Cifar10 ResNet
ResNet in the 2015 imagenet competition, the recognition rate reached a very high level, here I will use Caffe on Cifar10 to reproduce the paper 4.2 section of the CIFAR experiment. the basic module of ResNet Caffe Implementation the experimental results and explanations on CIFAR10 the basic module of ResNet
In this paper, we use Caffe to reproduce the experiment of resnet on the Cifar10 of Torch7. The basic module of ResNet can be the following Python code
.
Two intuitive implementation methods are as follows:
The two solutions are presented. For arrays with N elements, this process requires N-1 summation and log (N) steps. The span of Interleaved pair is the length of half an array.
The following is the recursive interleaved pair code (host ):
int recursiveReduce(int *data, int const size) { // terminate check if (size == 1) return data[0]; // renew the stride int const
latest results. The training convolution network on the thinning image is 21 higher than the newest result on the Mpiigaze dataset.
3.1.4 Application Details
Refine the network, rθ, as a residual network. Each residual network module contains 2 convolution layers, each containing 64 feature graphs, as shown in Figure 6.The 3x3 sized filter convolution 55x35 the size of the input image, outputting 64 feature graphs. The output passes through 4 residual modules. Finally, the output of the last 1
the specified pixel of an image.2. PixelFormat property: Returns the pixel format of the image.3. Palette properties: Gets and sets the color palette used by the image.4. Height Width Property: Returns the height and width of the image.5. LockBits method and Unlockbits method: Lock and unlock the bit pixels in the system memory respectively. Using LockBits and unlockbits in pixel-based image processing methods is a good way to allow us to specify the extent of the pixel to control any part of t
The bitmap class providesLockbitsAnd correspondingUnlockbitsMethods which enable you to fix a portion of the bitmap pixel data array in memory, access it directly and finally replace the bits inBitmap with the modified data.LockbitsReturnsBitmapdataClass that describes the layout and position of the data in the locked array.
The bitmapdata class contains the following important properties;
Scan0The address in memory of the fixed data array
StrideThe width, in bytes, of a single row of pixel d
data. length is not 50*3*60, but (50*3 + 2) * 60. In fact, in the readbitmap function, the length of BMP data is defined as BMP. height * stride-1, where stride is used instead of BMP. width * 3. This is because windwos requires that the length of a row to be scanned must be a multiple of 4 (in bytes). If not, it must be completed. Calculation formula: stride =

Direct input information to the output to protect the integrity of information, the entire network only learning input, output differences, simplifying learning goals, difficulty.The two-tier new learning unit consists of two identical output channel numbers 3x3 convolution. The three-layer residual network is used with the networks in network and the
preparations are ready, we can build the network. ResNet V2 is relatively complex, in order to reduce the amount of code to build a layer of ResNet v2, This article will take the auxiliary library to implement. The following code is based on my understanding of the ResNet network and existing resources ("TensorFlow combat" and so on) sorted out, and according to their own understanding added comments. Code comments Please correct me if there are any errors.

Think about how this is done, we slide the orange matrix (also called ' Stride ') on the original image (green) 1 pixels, 1 pixels, and in each position we multiply the corresponding elements of the two matrices to get an integer, which is the element of the output matrix (pink). Note that the 3x3 matrix is only "seen" at a time as part of the image input.
The 3x3 matrix is also calle
finally replace the original data in the bitmap with the modified data. Lockbits returns the position and distribution of the descriptive data in the locked matrix for each bitmapdata class. The bitmapdata class includes the following important attributes:
Scan0: Address of the data matrix in the memory.
Stride: the row width in the data matrix, in bytes. Several bytes may be extended, which will be described later.

In the structure, only stride is confusing. It is the number of bytes occupied by each line, for example:A row contains 11 pixels (width = 11). For a
