However, a large database may contain millions of objects, and clustering on such a large data set may lead to biased results. As data volumes and availability continue to grow, so does the need for large dataset analytics. Among the most commonly used clustering algorithms, K-means proved to be one of the most popular choices to provide acceptable results in a reasonable amount of time. In this paper, we present an improved k-means algorithm with better initial centroids. Also, we implement this modified algorithm on Hadoop platform. Experiments show that the improved k-means algorithm converges faster than the classic k-means and the average execution time is reduced compared to the traditional k-means.","PeriodicalId":90079,"journal":{"name":"...

Using the deep compression technology, the trained neural network model is re-trained and optimized in a targeted manner to ensure a compression ratio of 30%-50% under the premise that the accuracy is not degraded. In this way, the hardware storage resource configuration is more reasonable when the model is deployed on the embedded platform.","PeriodicalId":90079,"journal":{"name":"...

The diagnosis of skull fracture is essentially a special image classification problem. Recently, image classification methods based on deep learning have achieved good performance for general image classification. However, the effect of applying these methods to the diagnosis of skull fracture is not satisfactory. The reason is that it is difficult to distinguish the fracture regions from the background in the scanning image, and the extracted features of skull fracture and the background are very similar and indistinguishable. In order to solve the above problems, this paper proposed a novel skull fracture image classification approach based on attention mechanism, the proposed multi-scale transfer learning and residual network (ResNet), called attention-based multi-scale transfer ResNet (AMT-ResNet). In AMT-ResNet, attention mechanism is employed to give different focus to the feature information extracted by ResNet. In addition, the proposed multi-scale transfer learning is used to extract the common features from the multi-scale skull fracture images. Our proposed approach is evaluated on the datasets provided by Fujian medical university union hospital. Experimental results show that AMT-ResNet obtains better classification accuracy than other methods on skull fracture image classification.","PeriodicalId":90079,"journal":{"name":"...

Aiming at detecting image region of 1D barcodes, existing geometric approaches barely balance speed and precision. Deeplearning- based methods can locate 1D barcode fast but lack effective and accurate segmentation process, while pure geometric-based methods take unnecessary computational cost when processing high resolution image. We propose to integrate the deep-learning and geometric approaches, to tackle robust barcode localization in the presence of complicated background and accurate barcode detection within the localized region, respectively. Our integrated solution benefits the complementary advantages of the two methods. Through extensive experiments on standard benchmarks, we show our integrated approach outperforms the state-of-the-arts by at least 5 percentages.","PeriodicalId":90079,"journal":{"name":"...

Owners of distributed datasets can get an integrated model securely just by sharing and combining their sub models which are built on their respective sample sets, and generally the integrated model is more powerful than any sub model. However, sharing the sub models may cause serious privacy problems in some cases. So in this paper, we present a new method, based on which the data holders can integrate their sub polynomial regression models securely and efficiently without sharing them, and get the optimal combination regression model. In addition to theoretical analysis, we also verify the availability of the new method through experiments.","PeriodicalId":90079,"journal":{"name":"...

Experiments based on the ASVspoof 2017 Challenge data set show that the proposed method has a significant improvement in detection performance compared to the baseline system using Constant Q Cepstral Coefficients (CQCC), and the equal error rate (EER) is reduced by 18.20% under the same conditions, indicating that the performance of the CDECC feature is more effective than that of CQCC and MFCC features in detecting replay attack speech.","PeriodicalId":90079,"journal":{"name":"...

Stroke errors are the origins of most handwriting mistakes. Previous works have made some efforts on the types of errors extracted, while most of them are either preset by rules or deficient to include all types of stroke errors. For foreign students learning Chinese as a foreign language, especially beginners whose writing habits and characteristics are affected by ones of their native languages, methods by presetting are difficult to adopt. Therefore, this paper initiated from the data itself, proposes an adaptive approach to extract handwriting errors based on the result of the stroke matching which is accurate to sampling points in strokes. After the tagging list given as a matching index, the writing errors are adaptively extracted in different stroke errors of Chinese characters, including missing strokes, extra strokes, concatenated strokes, broken strokes, redundant strokes, incomplete strokes, the error of orientation and order. After serial experiments, the result indicates that the proposed approach is effective in extracting handwriting stroke errors.","PeriodicalId":90079,"journal":{"name":"...
