For BreaKHis dataset, the results reported in related works are the average of five trials, and the folds are provided along with the dataset to allow for a full comparison of classification results [9]. Breast cancer remains the most common type of cancer and the leading cause of cancer-induced mortality among women with 2.4 million new cases diagnosed and 523,000 deaths per year. The basic structure of the SE block is illustrated in Fig. Epub 2019 Nov 5. If targeting higher model compression, the other model compression algorithms should be used together. Our dataset is not only the largest publicly released dataset for breast cancer histopathological image classification, but it covers as many different subclasses spanning different age groups as possible, thus providing enough data diversity to alleviate the problem of relatively low classification … Breast cancer histopathology image classification through assembling multiple compact CNNs. The initial starting learning rate is 0.0004 and then it decreases exponentially every 10000 iterations. 2015. Sci Rep. 2016; 6:26286. Epub 2020 Nov 5. Corresponding to the C channels, the channel importance is denoted as $W_{L_{D}} = \left [w_{D1}, w_{D2},..., w_{DC}\right ]$. In: Computer Vision (ICCV), 2017 IEEE International Conference On. The deep learning models are employed to solve the classification problems in breast cancer detection[34]. Some attempts have already been made for automated grading of histopathological breast cancer images, but these studies have covered only limited amount of data or produce just a partial grading [6,7]. Deep learning for magnification independent breast cancer histopathology image classification. Berlin: Springer: 2013. p. 411–8. 7, in this paper we propose a special bagging scheme with 5 models. ResHist model learns rich and discriminative features from the histopathological images and classifies histopathological images into benign and malignant classes. Breiman L. Bagging predictors. To make the model more compact, the other traditional compression scheme Dynamic Network Surgery (DNS) [25] method, which can properly incorporate connection splicing into the training process to avoid incorrect pruning, is merged with our method. Second, by embedding the proposed Squeeze-Excitation-Pruning (SEP) block into our hybrid model, the channel importance can be learned and the redundant channels are thus removed. We have used networks pre-trained by the transfer learning on the ImageNet database and with fine-tuned output layers trained on histopathological images … The actual images are shown on the left, and four augmented samples (of the 20 created for each image) are shown on the right, Center patch and resized images from an original sample (left) and from an augmented sample (right), Training and validation accuracy for BC classification with 8 classes for the IRRCNN model at different magnification factors, Training and validation accuracy for the multi-class case using the 2015 BC Classification Challenge dataset. | The authors of work [11] train different patch-level CNNs and merge these models to predict the final image label based an improved existing CNN, and achieves state-of-the-art results on the large public breast cancer dataset [9]. Cancun: IEEE: 2016. p. 2440–5. This method uses a simple statistical analysis to impose the color characteristics of one image on another, and thus can achieve color correction by choosing an appropriate source image.

For example, the accuracy will drop sharply to 0.816 with 95% pruning ratio. Then the unimportant channels with lower weights are discarded to make the network compact. 8(b) some example images are shown. Computer-aided diagnosis provides a second option for image diagnosis, which can improve the reliability of experts’ decision-making. 2015. After global pooling, a statistic vector z∈RC is generated [27]. Breast cancer histopathology image analysis: A review. arXiv preprint arXiv:1502.03167. We propose a novel compact breast cancer histopathology image classification scheme by assembling multiple compact hybrid CNNs. In the training stage, the SEP performs like the original SE block: the C channels are connected to the scale module and then reweighted. IFMBE Proceedings, vol 69. Breast cancer causes hundreds of thousands of deaths each year worldwide. Recently, multi-classification of breast cancer from histopathological images was presented using a structured deep learning model called CSDCNN. Each hybrid model is obtained by using a subset of the training data. Deep learning and medical image processing for coronavirus (COVID-19) pandemic: A survey. In this paper, we set the specific target pruning ratio O=50%, and let the training loops R=1. From Table 4, one can notice that the similar phenomenon happens to F1 score, sensitivity and precision for our methods: local branch voting strategy achieves higher performance than global branch; hybrid model produces the optimal results.

ABSTRACT Breast cancer is one of the most common and deadly types of cancer that develops in the breast tissue of women worldwide. FZS constructed the model compression method. Although successful detection of malignant tumors from histopathological images largely depends on the long-term experience of radiologists, experts sometimes disagree with their decisions. 13 shows the recognition accuracies by using our channel pruning and DNS together. From the figure, one can see that under a certain pruning ratio threshold (say, 90%), the pruned network produces comparable accuracy (actually most points perform better) with the original model. Each WSI can have multiple normal, benign, in situ carcinoma and invasive carcinoma regions. This method achieves remarkable results on model size compression and time saving, but many different techniques need to be applied together. The Breast Cancer Histopathological Image Classification (BreakHis) is composed of 9,109 microscopic images of breast tumor tissue collected from 82 patients … Under the premise of guaranteeing this, we have introduced a channel pruning scheme to make our model more compact, which reduces the computing burden. Han Z, Wei B, Zheng Y, Yin Y, Li K, Li S. Breast cancer multi-classification from histopathological images with structured deep learning model. The weights and FLOPs of work [11] and [17] are also included in Table 7. 2021 Feb;65:102589. doi: 10.1016/j.scs.2020.102589. The inter- and intraobserver reproducibilities of the histopathological systems of breast cancer classification suggested by the World Health Organisation (WHO), the Armed Forces Institute of … USA.gov. By using the Max merging scheme, the recognition accuracy can be improved to 85.1% and 79.3%, respectively. Zhu, C., Song, F., Wang, Y. et al. At last, with different data partition and composition, we build multiple models and assemble them together to further enhance the model generalization ability. In work [9], the authors introduce a large, publicly available and annotated dataset, which is composed of 7909 clinically representative, microscopic images of breast tumor tissue images collected from 82 patients. The contributions of this paper are summarized in the following: A hybrid CNN architecture is designed, which contains a global model branch and a local model branch. 4. (eds) 7th International Conference on the Development of Biomedical Engineering in Vietnam (BME7). Exemplar images collected from (a) BreaKHis dataset and (b) BACH dataset. A comparative analysis has been done with the existing deep learning methods. Article 12(a). IEEE Trans Biomed Eng. Dataset. Noteworthily, most classification methods are performed on low-resolution images with different magnifications. Deep learning as a tool for increased accuracy and efficiency of histopathological diagnosis. However, color variation happens due to differences in staining procedures, and these color differences of the histology images may adversely affect the training and inference process in CNNs. Chuang Zhu. In this study, a breast cancer histopathology image classification by assembling multiple compact CNNs is proposed. YW collected the data and conduct image preprocessing and augmentation it. We have proposed breast cancer histopathology image classification based on assembling multiple compact CNNs. In this paper, we implemented deep neural networks ResNet18, InceptionV3 and ShuffleNet for binary classification of breast cancer in histopathological images. The black line represents the compressed model accuracy [0.851,0.878,0.877,0.883] with R from 1 to 4; the red dotted line denotes the corresponding pruning proportion X [0.8,0.55,0.42,0.33] for each loop under 4 different situations. The normal tissue and benign lesion are labeled as the benign class, and in situ carcinoma coupled with invasive carcinoma are treated as cancer lesion. From the figure we can see that the joint approach far outperforms the results only using DNS, especially in the small model size range. Sensors (Basel). Proposed hybrid CNN architecture. Precisely, it is composed of 9,109 microscopic images of breast tumour tissue collected from 82 patients using different Automatic histopathology image recognition plays a key role in speeding up diagnosis and improving the quality of diagnosis. 5. Song F, Wang Y, Guo Y, Zhu C, Liu J, Jin M. A channel-level pruning strategy for convolutional layers in cnns. In this work, we propose a breast cancer histopathology image classification by assembling multiple compact Convolutional Neural Networks (CNNs). Breast Cancer Histopathological Image Classification: A Deep Learning Approach. Chen W, Wilson J, Tyree S, Weinberger K, Chen Y. Compressing neural networks with the hashing trick. A Dataset for Breast Cancer Histopathological Image Classification. More specifically, we systematically study two recent milestones of CNNs, i.e., VggNet and ResNet, for breast cancer histopathological image classification. The early stage diagnosis and treatment can significantly reduce the mortality rate [3]. By embedding the SEP block into our hybrid model, the channel importance can be learned and the redundant channels are then removed. 8(a). For method 1, each input image is directly processed by the global model. For the fair comparison, the same dataset partition and fold segmentation are used in our test. Thus the activation factors are chosen as channel weights for model compression. Helsinki: ACM: 2014. p. 675–8. Golatkar et al. In the following, we will detail the channel pruning flow of our scheme. Then different classification models can be constructed by using different training and validating set splittings, as shown in Fig. Deniz [9, 10,11,12,16]. The training subset is used to train multiple models and the testing subset is adopted to evaluate the performance of our model assembling strategy. Unlike the augmentation methods (rotation with fixed angles) in [12], we rotate the images randomly. In our model, totally seven Inception layers are integrated to address the problem of gradients vanishing/exploding, which guarantees the performance of deeper models. In the future, we will involve the experience of the pathologists to guide our model design. 2016; 35(11):2369–80. Article 2. Background. As shown in Fig. volume 19, Article number: 198 (2019) This task can be improved by the use of Computer Aided Diagnosis (CAD) systems, reducing the time of diagnosis and reducing the inter and intra-observer variability. The excitation operation can explicitly model interdependencies between channels. Privacy 9. With the increase of pruning ratio, our model will have the smallest amount of weights. Biopsies are the gold standard for breast cancer diagnosis. The proposed SEP block. First, histopathological images of breast cancer are fine-grained, high-resolution images that depict rich geometric structures and complex textures. Our method can be used in breast cancer auxiliary diagnostic scenario, and it can reduce the workload of pathologists as well as improve the quality of diagnosis. the Inception module), they are first passed through a squeezing operation, which aggregates the feature maps across spatial dimensions W×H to produce a 1×1×C channel descriptor. In detail, the entire dataset is first randomly divided into two parts: a training set and a testing set. Breast cancer is a heterogeneous disease, composed of numerous entities with distinctive biological, histological and clinical characteristics [].This malignancy erupts from the growth of abnormal breast cells and might invade the adjacent healthy tissues [].Its clinical screening is initially performed by utilizing radiology images… The annotation of the whole-slide images was performed by two medical experts and images where there was disagreement were discarded. With 50% channel pruning, accuracy, F1 score, sensitivity and precision are listed in Table 5 and Table 6. The performance of our hybrid model is further analyzed by drawing the associated ROC curve, as shown in Fig. The IRRCNN shows superior performance against equivalent Inception Networks, Residual Networks, and RCNNs for object recognition tasks. This means that the local information and global information can effectively work together to make the decision. The continuum of intraductal breast lesions, which encompasses the usual ductal hyperplasia (UDH), atypical ductal hyperplasia (ADH), and ductal carcinoma in situ (DCIS), are a group of cytologically and architecturally diverse profilerations, typically originating from the terminal duct-lobular unit and confined to the mammary duct lobular system []. In this paper, we conduct some preliminary experiments using the deep learning approach to classify breast cancer histopathological images from BreaKHis, a publicly dataset available at … The Inception network consists of 1 ×1, 3 ×3, 5 ×5 filters, and 3 ×3 max pooling. 2, we connect each Inception module to a SEP block, which is used to compress our model. Typically, the algorithms of the literature can be classified into two categories. Thus, we just compare our method without the multi-model assembling technique to the other works for BreakHis dataset. The global and local model branch adopt the same CNN structure, as shown in Fig. 2020 Feb;30(2):778-788. doi: 10.1007/s00330-019-06457-5. Article Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. Then voting is performed to classify the input image based on the average of 15 predictions. DCNNs have already provided superior performance in different modalities of medical imaging including breast cancer classification, segmentation, and detection. This tells that by increasing training loops R our model performance will be further improved slightly, but more training loops (computing resources) will be needed. The larger CNNs produce stronger representation power, but consume larger on-chip/off-chip memory and utilize more computing resource, which leads to higher diagnosing latency in many real-world clinical applications.

Generally, great efforts and effective expert domain knowledge are required to design appropriate features for this type of method. The strategies we used include random rotation, flipping transformation and shearing transformation. (g) (h): Histograms of importance distributions for the pruned network, Classification accuracy, FLOPs and weights under different pruning ratios. The database is composed of 7,909 image samples generated from breast tissue biopsy slides, which are stained with HE. We have used networks pre-trained by the transfer learning on the ImageNet database and with fine-tuned output layers trained on histopathological images from the public dataset BreakHis. By using these model weights and the corresponding activation layers, the C activation factors s1, s2,..., sC corresponding to C channels of one layer can be calculated. z=[z1,...,zi,...,zC], and the i-th element of z is calculated by: Then an excitation operation is performed on the generated channel descriptor to learn the sample-specific activation factor s=[s1,s2,...,sC] for C channels by using two fully-connected (FC) layers and two corresponding activation layers (ReLu and Sigmoid). All authors have read and approved the manuscript. In this work, we propose an algorithm for training deep neural networks for classification of breast cancer in histopathological images affected by data unbalance with support of active learning.
