当核大小为7×7时，与卷积核大小为3×3的情况相同，MB的两个输出并不完全管道化。这两个输出需要分别累积6和2个时钟周期，但它们输出的时钟比仍为3:1，这意味着DSP利用率仍可保持在很高的水平。为了获得正确且错误率低的累积结果，仍需对卷积核进行适当的零设置。

A. Encoding Network of PFSPNet The encoding network is divided into three parts. In the part I, RNN is adopted to model the processing time pij of job i on all machines, which can be converted into a fixed dimensional vector pi. In the part II, the number of machines m is integrated into the vector pi through the fully connected layer, and the fixed dimensional vector p˜i is output. In the part III, p˜i is fed into the convolution layer to improve the expression ability of the network, and the final output η p= [ η p1, η p2,..., η pn] is obtained. Fig. 2 illustrates the encoding network. In the part I, the modelling process for pij is described as follows, where WB, hij , h0 are k-dimensional vectors, h0, U, W, b and WB are the network parameters, and f() is the mapping from RNN input to hidden layer output. The main steps of the part I are shown as follows. Step 1: Input pij to the embedding layer and then obtain the output yij = WB pij ; Step 2: Input yi1 and h0 to the RNN and then obtain the hidden layer output hi1 = f(yi1,h0; U,W, b). Let p1 = h1m ; Step 3: Input yij and hi,j−1, j = 2, 3 ··· , m into RNN in turn, and then obtain the hidden layer output hij = f(yij ,hi,j−1; U,W, b), j = 2, 3 ··· , m. Let pi = him . In the part II, the number of machines m and the vector pi are integrated by the fully connected layer. The details are described as follows. WB and h˜i are d-dimensional vectors, WB W and ˜b are network parameters, and g() denotes the mapping from the input to the output of full connection layer. Step 1: Input the number of machines m to the embedding layer, and the output m = WB m is obtained。Step 2: Input m and pi to the fully connected layer and then obtain the output hi = g([m, pi];W, b); Step 3: Let pi = Relu(hi). In the part III, pi, i = 1, 2,...,n are input into onedimensional convolution layer. The final output vector η pi, i = 1, 2, ··· , n are obtained after the output of convolutional layer goes through the Relu layer.首先逐行仔细的分析此过程，其次怎么使用pytorch用EncoderNetwork类完全实现这个过程的所有功能和步骤

Write a function with the declaration: smoothed=rectFilt(x,width). The filter should take a vector of noisy data (x) and smooth it by doing a symmetric moving average with a window of the specified width. For example if width=5, then smoothed(n) should equal mean(x(n-2:n+2)). Note that you may have problems around the edges: when n<3 and n>length(x)-2. a. The lengths of x and smoothed should be equal. b. For symmetry to work, make sure that width is odd. If it isn’t, increase it by 1 to make it odd and display a warning, but still do the smoothing. c. Make sure you correct edge effects so that the smoothed function doesn’t deviate from the original at the start or the end. Also make sure you don’t have any horizontal offset between the smoothed function and the original (since we’re using a symmetric moving average, the smoothed values should lie on top of the original data). d. You can do this using a loop and mean (which should be easy but may be slow), or more efficiently by using conv (if you are familiar with convolution). e. Load the mat file called noisyData.mat. It contains a variable x which is a noisy line. Plot the noisy data as well as your smoothed version, like below (a width of 11 was used):

% smoothed = rectFilt(x, width) returns a vector that is the same size as x, where each element in the vector is the % mean of a symmetric window of width 'width' centered around that element in x. %...

翻译这段英文，并解释： Deploying convolutional neural networks (CNNs) on em-bedded devices is difficult due to the limited memory and computation resources. The redundancy in feature maps is an important characteristic of those successful CNNs, but has rarely been investigated in neural architecture de-sign. This paper proposes a novel Ghost module to generate more feature maps from cheap operations. Based on a set of intrinsic feature maps, we apply a series of linear transformations with cheap cost to generate many ghost Feature maps that could fully reveal information underlying intrinsic features. The proposed Ghost module can be taken as a plug-and-play component to upgrade existing convo-lutional neural networks. Ghost bottlenecks are designed to stack Ghost modules, and then the lightweight Ghost-Net can be easily established. Experiments conducted on benchmarks demonstrate that the proposed Ghost module is an impressive alternative of convolution layers in baseline models, and our GhostNet can achieve higher recognition performance (e.g. 75.7% top-I accuracy) than MobileNetV3 with similar computational cost on the ImaseNet ILSVRC2012 classification dataset.

As a result, the number of total parameters was reduced by almost 100%35 and classification accuracy was improved. The total number of parameters used was 39,553. In this architecture, we took image information more directly after applying max-pooling and merged it with information generated after convolutions. Features in the convolution layer are more generic (e.g., blobs, textures, edges, etc.). So, adding image information directly will create more specific information for each case. After merging, another convolution and max pooling layer before the final classification layer maintains the generic information about the image and can provide more features of about the image for getting a better classification result.

The conventional convolution neural network (CNN) adopts softmax function as classifier, which has problems of overflow and underflow. This paper proposes a rolling bearing intelligent fault diagnosis method based on multi-scale convolution neural network, bi-directional long short term memory and support vector machine (MCNN-BiLSTM-SVM). The wavelet threshold denoising algorithm is adopted for signal preprocessing. The multi-scale convolution neural network (MCNN) and the bidirectional long short-term memory network (BiLSTM) are combined as the feature extractor to improve feature extraction capability. The support vector machine (SVM) is adopted as the classifier to improve classification performance. Transfer learning is used in MCNN-BiLSTM-SVM for different conditions. According to the experiments, the proposed MCNN-BiLSTM-SVM fault diagnosis method has higher diagnostic accuracy, stronger anti-noise performance and better stability under different conditions than other diagnostic methods.给出以上内容审稿意见

Traditional network security situation prediction methods depend on the accuracy of historical situation value. Moreover, there are differences in correlation and importance among various network security factors. In order to solve these problems, a combined prediction model based on the temporal convolution attention network (TCAN) and bi-directional gate recurrent unit (BiGRU) network optimized by singular spectrum analysis (SSA) and improved quantum particle swarm optimization algorithm (IQPSO) was proposed. This model was first decomposed and reconstructed into a series of subsequences through the SSA of network security situation data. Next, a prediction model of TCAN-BiGRU was established for each subsequence, respectively. The TCN with relatively simple structure was used in the TCAN to extract features from the data. Besides, the improved channel attention mechanism (CAM) was used to extract important feature information from TCN. Afterwards, the before-after status of the learning situation value of the BiGRU neural network was used to extract more feature information from sequences for prediction. Meanwhile, an improved IQPSO was proposed to optimize the hyper-parameter of the BiGRU neural network. Finally, the prediction results of subsequence were superimposed to obtain the final predicted value. In the experiment, on the one hand, the IQPSO was compared with other optimization algorithms; and the results showed that the IQPSO has better optimization performance; on the other hand, the comparison with traditional prediction methods was performed through the simulation experiment and the established prediction model; and the results showed that the combined prediction model established has higher prediction accuracy.
