The OASIS-MRI database is a nuclear magnetic resonance biomedical image database [52] established by OASIS, which is used only for scientific research. For the performance in the TCIA-CT database, only the algorithm proposed in this paper obtains the best classification results. (2)Because deep learning uses automatic learning to obtain the feature information of the object measured by the image, but as the amount of calculated data increases, the required training accuracy is higher, and then its training speed will be slower. The latter three corresponding deep learning algorithms can unify the feature extraction and classification process into one whole to complete the corresponding test. Applying SSAE to image classification has the following advantages:(1)The essence of deep learning is the transformation of data representation and the dimensionality reduction of data. In addition, the medical image classification algorithm of the deep learning model is still very stable. The statistical results are shown in Table 3. Initialize the network parameters and give the number of network layers, the number of neural units in each layer, the weight of sparse penalty items, and so on. This is because the deep learning model constructed by these two methods is less intelligent than the method proposed in this paper. This method separates image feature extraction and classification into two steps for classification operation. In this article, we will discuss how Convolutional Neural Networks (CNN) classify objects from images (Image Classification) from a bird’s eye view. That is to say, to obtain a sparse network structure, the activation values of the hidden layer unit nodes must be mostly close to zero. In this project, we will introduce one of the core problems in computer vision, which is image classification. I don’t even have a good enough machine.” I’ve heard this countless times from aspiring data scientists who shy away from building deep learning models on their own machines.You don’t need to be working for Google or other big tech firms to work on deep learning datasets! Section 4 constructs the basic steps of the image classification algorithm based on the stacked sparse coding depth learning model-optimized kernel function nonnegative sparse representation. This method was first proposed by David in 1999, and it was perfected in 2005 [23, 24]. 2019M650512), and Scientific and Technological Innovation Service Capacity Building-High-Level Discipline Construction (city level). It can be seen from Figure 7, it is derived from an example in each category of the database. It facilitates the classification of late images, thereby improving the image classification effect. The basic idea of the image classification method proposed in this paper is to first preprocess the image data. Accelerating the pace of engineering and science, MathWorksはエンジニアや研究者向け数値解析ソフトウェアのリーディングカンパニーです。, 'http://download.tensorflow.org/example_images/flower_photos.tgz', % Find the first instance of an image for each category, % Determine the smallest amount of images in a category, % Limit the number of images to reduce the time it takes. proposed an image classification method combining a convolutional neural network and a multilayer perceptron of pixels. The Top-5 test accuracy rate has increased by more than 3% because this method has a good test result in Top-1 test accuracy. Deep-learning-based image classification with MVTec HALCON allows to easily assign images to trained classes without the need of specially labeled data – a simple grouping of the images after data folders is sufficient. The deep learning model has a powerful learning ability, which integrates the feature extraction and classification process into a whole to complete the image classification test, which can effectively improve the image classification accuracy. Therefore, adding the sparse constraint idea to deep learning is an effective measure to improve the training speed. It solves the approximation problem of complex functions and constructs a deep learning model with adaptive approximation ability. In order to improve the classification effect of the deep learning model with the classifier, this paper proposes to use the sparse representation classification method of the optimized kernel function to replace the classifier in the deep learning model. It can be known that the convergence rate of the random coordinate descent method (RCD) is faster than the classical coordinate descent method (CDM) and the feature mark search FSS method. The accuracy of the method proposed in this paper is significantly higher than that of AlexNet and VGG + FCNet. Other MathWorks country sites are not optimized for visits from your location. It is used to measure the effect of the node on the total residual of the output. Next, we will make use of CycleGAN [19] to augment our data by transferring styles from images in the dataset to a fixed predetermined image such as Night/Day theme or Winter/Summer. 2020, Article ID 7607612, 14 pages, 2020. https://doi.org/10.1155/2020/7607612, 1School of Information, Beijing Wuzi University, Beijing 100081, China, 2School of Physics and Electronic Electrical Engineering, Huaiyin Normal of University, Huaian, Jiangsu 223300, China, 3School of Information and Electronics, Beijing Institute of Technology, Beijing 100081, China. To further verify the universality of the proposed method. The network structure of the automatic encoder is shown in Figure 1. The image classification is a classical problem of image processing, computer vision and machine learning fields. The reason that the recognition accuracy of AlexNet and VGG + FCNet methods is better than HUSVM and ScSPM methods is that these two methods can effectively extract the feature information implied by the original training set.

According to the Internet Center (IDC), the total amount of global data will reach 42ZB in 2020. In the ideal case, only one coefficient in the coefficient vector is not 0. "Very deep convolutional networks for large-scale image recognition." It can be seen from Table 2 that the recognition rate of the proposed algorithm is high under various rotation expansion multiples and various training set sizes. Algorithms under Deep Learning process information the same way the human brain does, but obviously on a very small scale, since our brain is too complex (our brain has around 86 billion neurons). The basic flow chart of the proposed image classification algorithm is shown in Figure 4. Part 2: Training a Santa/Not Santa detector using deep learning (this post) 3. 1. Typically, Image Classification refers to images in which only one object appears and is analyzed. In DNN, the choice of the number of hidden layer nodes has not been well solved. However, this type of method has problems such as dimensionality disaster and low computational efficiency. In particular, the LBP + SVM algorithm has a classification accuracy of only 57%. The block size and rotation expansion factor required by the algorithm for reconstructing different types of images are not fixed. It can increase the geometric distance between categories, making the linear indivisible into linear separable. At the same time, combined with the basic problem of image classification, this paper proposes a deep learning model based on the stacked sparse autoencoder. CVPR 2009. The algorithm is used to classify the actual images. Copyright © 2020 Jun-e Liu and Feng-Ping An. CNNs represent a huge breakthrough in image recognition. It can improve the image classification effect. , ci ≥ 0, ≥ 0. It can be seen from Table 1 that the recognition rates of the HUSVM and ScSPM methods are significantly lower than the other three methods. It can train the optimal classification model with the least amount of data according to the characteristics of the image to be tested. For the two classification problem available,where ly is the category corresponding to the image y. The sparsity constraint provides the basis for the design of hidden layer nodes. Jing, F. Wu, Z.

Therefore, if you want to achieve data classification, you must also add a classifier to the last layer of the network. Then, the output value of the M-1 hidden layer training of the SAE is used as the input value of the Mth hidden layer. We will be providing unlimited waivers of publication charges for accepted research articles as well as case reports and case series related to COVID-19. This method is better than ResNet, whether it is Top-1 test accuracy or Top-5 test accuracy. In the case where the proportion of images selected in the training set is different, there are certain step differences between AlexNet and VGG + FCNet, which also reflects the high requirements of the two models for the training set. In order to further verify the classification effect of the proposed algorithm on medical images. The procedure will look very familiar, except that we don't need to fine-tune the classifier. The number of hidden layer nodes in the self-encoder is less than the number of input nodes. According to the setting in [53], this paper also obtains the same TCIA-CT database of this DICOM image type, which is used for the experimental test in this section. Therefore, its objective function becomes the following:where λ is a compromise weight. Section 5 analyzes the image classification algorithm proposed in this paper and compares it with the mainstream image classification algorithm. From left to right, the images of the differences in pathological information of the patient's brain image. This section will conduct a classification test on two public medical databases (TCIA-CT database [51] and OASIS-MRI database [52]) and compare them with mainstream image classification algorithms. Zhang et al. Even within the same class, its difference is still very large. The image classification algorithm is used to conduct experiments and analysis on related examples. countEachLabel | activations (Deep Learning Toolbox) | alexnet (Deep Learning Toolbox) | classificationLayer (Deep Learning Toolbox) | convolution2dLayer (Deep Learning Toolbox) | deepDreamImage (Deep Learning Toolbox) | fullyConnectedLayer (Deep Learning Toolbox) | imageInputLayer (Deep Learning Toolbox) | maxPooling2dLayer (Deep Learning Toolbox) | predict (Deep Learning Toolbox) | reluLayer (Deep Learning Toolbox) | confusionmat (Statistics and Machine Learning Toolbox) | fitcecoc (Statistics and Machine Learning Toolbox). この例の変更されたバージョンがシステム上にあります。代わりにこのバージョンを開きますか? It only has a small advantage. The specific experimental results are shown in Table 4. The weights obtained by each layer individually training are used as the weight initialization values of the entire deep network. If the number of hidden nodes is more than the number of input nodes, it can also be automatically coded. Then, the kernel function is sparse to indicate that the objective equation is. The deep learning algorithm proposed in this paper not only solves the problem of deep learning model construction, but also uses sparse representation to solve the optimization problem of classifier in deep learning algorithm. In 2018, Zhang et al. Choose a web site to get translated content where available and see local events and offers. The dataset is commonly used in Deep Learning for testing models of Image Classification. Image classification began in the late 1950s and has been widely used in various engineering fields, human-car tracking, fingerprints, geology, resources, climate detection, disaster monitoring, medical testing, agricultural automation, communications, military, and other fields [14–19]. For the first time in the journal science, he put forward the concept of deep learning and also unveiled the curtain of feature learning. In the microwave oven image, the appearance of the same model product is the same. (3)The approximation of complex functions is accomplished by the sparse representation of multidimensional data linear decomposition and the deep structural advantages of multilayer nonlinear mapping. Since the calculation of processing large amounts of data is inevitably at the expense of a large amount of computation, selecting the SSAE depth model can effectively solve this problem. % Get the network weights for the second convolutional layer, % Scale and resize the weights for visualization, % Display a montage of network weights. % Notice that each set now has exactly the same number of images. Therefore, sparse constraints need to be added in the process of deep learning. [32] proposed a Sparse Restricted Boltzmann Machine (SRBM) method. The final classification accuracy corresponding to different kinds of kernel functions is different. The SSAEs are stacked by an M-layer sparse autoencoder, where each adjacent two layers form a sparse autoencoder. Based on the study of the deep learning model, combined with the practical problems of image classification, this paper, sparse autoencoders are stacked and a deep learning model based on Sparse Stack Autoencoder (SSAE) is proposed. The model we will use was pretrained on the ImageNet dataset, which contains over 14 million images and over 1'000 classes. The SSAE depth model directly models the hidden layer response of the network by adding sparse constraints to the deep network. During learning, if a neuron is activated, the output value is approximately 1. This paper verifies the algorithm through daily database, medical database, and ImageNet database and compares it with other existing mainstream image classification algorithms. The SSAE model proposed in this paper is a new network model architecture under the deep learning framework. Then, through the deep learning method, the intrinsic characteristics of the data are learned layer by layer, and the efficiency of the algorithm is improved. Assuming that images are a matrix of , the autoencoder will map each image into a column vector ∈ Rd, , then n training images form a dictionary matrix, that is, . Some scholars have proposed image classification methods based on sparse coding. Jing et al. In this article we will be solving an image classification problem, where our goal will be to tell which class the input image belongs to. h (l) represents the response of the hidden layer. These large numbers of complex images require a lot of data training to dig into the deep essential image feature information. The HOG + KNN, HOG + SVM, and LBP + SVM algorithms that performed well in the TCIA-CT database classification have poor classification results in the OASIS-MRI database classification. To extract useful information from these images and video data, computer vision emerged as the times require. Firstly, the sparse representation of good multidimensional data linear decomposition ability and the deep structural advantages of multilayer nonlinear mapping are used to complete the approximation of the complex function of the deep learning model training process. It can be seen from Table 3 that the image classification algorithm based on the stacked sparse coding depth learning model-optimized kernel function nonnegative sparse representation is compared with the traditional classification algorithm and other depth algorithms. These applications require the manual identification of objects and facilities in the imagery. Therefore, this method became the champion of image classification in the conference, and it also laid the foundation for deep learning technology in the field of image classification. For example, in the coin image, although the texture is similar, the texture combination and the grain direction of each image are different. The SSAE model is an unsupervised learning model that can extract high autocorrelation features in image data during training, and it can also alleviate the optimization difficulties of convolutional networks. [2] Krizhevsky, Alex, Ilya Sutskever, and Geoffrey E. Hinton. With deep learning this has changed: given the right conditions, many computer vision tasks no longer require such careful feature crafting. However, the sparse characteristics of image data are considered in SSAE. In order to reflect the performance of the proposed algorithm, this algorithm is compared with other mainstream image classification algorithms. The residual for layer l node i is defined as . The classification of images in these four categories is difficult; even if it is difficult for human eyes to observe, let alone use a computer to classify this database. Basic flow chart of image classification algorithm based on stack sparse coding depth learning-optimized kernel function nonnegative sparse representation. However, these systems require an excessive amount … So, it needs to improve it to. コマンドを MATLAB コマンド ウィンドウに入力して実行してください。Web ブラウザーは MATLAB コマンドをサポートしていません。. Its sparse coefficient is determined by the normalized input data mean. is where you specify the image size, which, in this case, is 28-by-28-by-1. The sparse autoencoder [42, 43] adds a sparse constraint to the autoencoder, which is typically a sigmoid function. Therefore, this paper proposes an image classification algorithm based on the stacked sparse coding depth learning model-optimized kernel function nonnegative sparse representation. Image Classification Report 2 ACKNOWLEDGEMENT: I would like to express my special thanks of gratitude to “Indian Academy of Sciences, Bengaluru” as well as my guide Prof. B.L. This section uses Caltech 256 [45], 15-scene identification data set [45, 46], and Stanford behavioral identification data set [46] for testing experiments. In the process of deep learning, the more layers of sparse self-encoding and the feature expressions obtained through network learning are more in line with the characteristics of data structures, and it can also obtain more abstract features of data expression. (5)Based on steps (1)–(4), an image classification algorithm based on stacked sparse coding depth learning model-optimized kernel function nonnegative sparse representation is established. Finally, an image classification algorithm based on stacked sparse coding depth learning model-optimized kernel function nonnegative sparse representation is established. This paper chooses to use KL scatter (Kullback Leibler, KL) as the penalty constraint:where s2 is the number of hidden layer neurons in the sparse autoencoder network, such as the method using KL divergence constraint, then formula (4) can also be expressed as follows: When , , if the value of differs greatly from the value of ρ, then the term will also become larger. Deep Learning, Semantic Segmentation, and Detection Image Category Classification and Image Retrieval Image Category Classification Using Deep Learning On … Although there are angle differences when taking photos, the block rotation angles on different scales are consistent. % Tabulate the results using a confusion matrix. Since the learning data sample of the SSAE model is not only the input data, but also used as the target comparison image of the output image, the SSAE weight parameter is adjusted by comparing the input and output, and finally the training of the entire network is completed. SIFT looks for the position, scale, and rotation invariants of extreme points on different spatial scales. For a multiclass classification problem, the classification result is the category corresponding to the minimum residual rs. "Decaf: A deep convolutional activation feature for generic visual recognition." The experimental results show that the proposed method not only has a higher average accuracy than other mainstream methods but also can be good adapted to various image databases. This is also the main reason why the deep learning image classification algorithm is higher than the traditional image classification method. To achieve the goal of constraining each neuron, usually ρ is a value close to 0, such as ρ = 0.05, i.e., only 5% chance is activated. For example, Zhang et al. (1) Image classification methods based on statistics: it is a method based on the least error, and it is also a popular image statistical model with the Bayesian model [20] and Markov model [21, 22]. When ci≠0, the partial derivative of J (C) can be obtained: Calculated by the above mentioned formula,where k . These two methods can only have certain advantages in the Top-5 test accuracy. The convolutional neural network (CNN) is a class of deep learning neural networks. Therefore, when identifying images with a large number of detail rotation differences or partial random combinations, it must rotate the small-scale blocks to ensure a high recognition rate. Train Deep Learning Network to Classify New Images This example shows how to use transfer learning to retrain a convolutional neural network to classify a new set of images. In the real world, because of the noise signal pollution in the target column vector, the target column vector is difficult to recover perfectly. The images covered by the above databases contain enough categories. Its structure is similar to the AlexNet model, but uses more convolutional layers. In 2015, Girshick proposed the Fast Region-based Convolutional Network (Fast R-CNN) [36] for image classification and achieved good results. When the training set ratio is high, increasing the rotation expansion factor reduces the recognition rate. Introduction Image classification using deep learning algorithm is considered the state-of-the-art in computer vision researches. Part 3: Deploying a Santa/Not Santa deep learning detector to the Raspberry Pi (next week’s post)In the first part of thi… An example picture is shown in Figure 7. Specifying ρ sparsity parameter in the algorithm represents the average activation value of the hidden neurons, i.e., averaging over the training set. The model can effectively extract the sparse explanatory factor of high-dimensional image information, which can better preserve the feature information of the original image. In DNN, the choice of the number of hidden layer nodes has not been well solved. (3) Image classification method based on shallow learning: in 1986, Smolensky [28] proposed the Restricted Boltzmann Machine (RBM), which is widely used in feature extraction [29], feature selection [30], and image classification [31]. I believe image classification is a great start point before diving into other computer vision fields, espaciallyfor begginers who know nothing about deep learning. In summary, the structure of the deep network is designed by sparse constrained optimization. The Automatic Encoder Deep Learning Network (AEDLN) is composed of multiple automatic encoders. It can be seen that the gradient of the objective function is divisible and its first derivative is bounded. The particle loss value required by the NH algorithm is li,t = r1. The database contains a total of 416 individuals from the age of 18 to 96. This method has many successful applications in classic classifiers such as Support Vector Machine. This paper proposes the Kernel Nonnegative Sparse Representation Classification (KNNSRC) method for classifying and calculating the loss value of particles. The premise that the nonnegative sparse classification achieves a higher classification correct rate is that the column vectors of are not correlated.

It will build a deep learning model with adaptive approximation capabilities. And more than 70% of the information is transmitted by image or video. In 2017, Lee and Kwon proposed a new deep convolutional neural network that is deeper and wider than other existing deep networks for hyperspectral image classification [37]. Let us start with the difference between an image and an object from a computer-vision context. At present, computer vision technology has developed rapidly in the field of image classification [1, 2], face recognition [3, 4], object detection [5–7], motion recognition [8, 9], medicine [10, 11], and target tracking [12, 13]. It can improve the image classification effect. On this basis, this paper proposes an image classification algorithm based on stacked sparse coding depth learning model-optimized kernel function nonnegative sparse representation. Comparison table of classification results of different classification algorithms on ImageNet database (unit: %). The TCIA-CT database is an open source database for scientific research and educational research purposes.
