A Noise Extraction Method for Cryo-EM Single-Particle Denoising
Journal on Big Data, Vol.4, No.1, pp. 61-76, 2022, DOI:10.32604/jbd.2022.028078
Abstract Cryo-Electron Microscopy (cryo-EM) has become a powerful method to study the structure and function of biological macromolecules. However, in clustering tasks based on the projection angle of particles in cryo-EM, the noise considerably affects the clustering results. Existing denoising algorithms are ineffective due to the extremely low signal-to-noise ratio (SNR) of cryo-EM images and the complexity of noise types. The noise of a single particle greatly influences the orientation estimation of the subsequent clustering task, and the result of the clustering task directly affects the accuracy of the 3D reconstruction. In this paper, we propose… More >

Research and Practice of Telecommunication User Rating Method Based on Machine Learning
Journal on Big Data, Vol.4, No.1, pp. 27-39, 2022, DOI:10.32604/jbd.2022.026850
Abstract The machine learning model has advantages in multi-category credit rating classification. It can replace discriminant analysis based on statistical methods, greatly helping credit rating reduce human interference and improve rating efficiency. Therefore, we use a variety of machine learning algorithms to study the credit rating of telecom users.

Social Opinion Network Analytics in Community Based Customer Churn Prediction
Journal on Big Data, Vol.4, No.2, pp. 87-95, 2022, DOI:10.32604/jbd.2022.024533
Abstract Community based churn prediction, or the assignment of recognising the influence of a customer’s community in churn prediction has become an important concern for firms in many different industries. While churn prediction until recent times have focused only on transactional dataset (targeted approach), the untargeted approach through product advisement, digital marketing and expressions in customer’s opinion on the social media like Twitter, have not been fully harnessed. Although this data source has become an important influencing factor with lasting impact on churn management. Since Social Network Analysis (SNA) has become a blended approach for churn… More >

A New Population Initialization of Particle Swarm Optimization Method Based on PCA for Feature Selection
Journal on Big Data, Vol.3, No.1, pp. 1-9, 2021, DOI:10.32604/jbd.2021.010364
Abstract In many fields such as signal processing, machine learning, pattern
recognition and data mining, it is common practice to process datasets containing
huge numbers of features. In such cases, Feature Selection (FS) is often involved.
Meanwhile, owing to their excellent global search ability, evolutionary
computation techniques have been widely employed to the FS. So, as a powerful
global search method and calculation fast than other EC algorithms, PSO can solve
features selection problems well. However, when facing a large number of feature
selection, the efficiency of PSO drops significantly. Therefore, plenty of works
have been… More >

OPPR: An Outsourcing Privacy-Preserving JPEG Image Retrieval Scheme with Local Histograms in Cloud Environment
Journal on Big Data, Vol.3, No.1, pp. 21-33, 2021, DOI:10.32604/jbd.2021.015892
Abstract As the wide application of imaging technology, the number of big
image data which may containing private information is growing fast. Due to
insufficient computing power and storage space for local server device, many
people hand over these images to cloud servers for management. But actually, it
is unsafe to store the images to the cloud, so encryption becomes a necessary step
before uploading to reduce the risk of privacy leakage. However, it is not
conducive to the efficient application of image, especially in the Content-Based
Image Retrieval (CBIR) scheme. This paper proposes an outsourcing… More >

Grain Yield Predict Based on GRA-AdaBoost-SVR Model
Journal on Big Data, Vol.3, No.2, pp. 65-76, 2021, DOI:10.32604/jbd.2021.016317
Abstract Grain yield security is a basic national policy of China, and changes in
grain yield are influenced by a variety of factors, which often have a complex,
non-linear relationship with each other. Therefore, this paper proposes a Grey
Relational Analysis–Adaptive Boosting–Support Vector Regression (GRAAdaBoost-SVR) model, which can ensure the prediction accuracy of the model
under small sample, improve the generalization ability, and enhance the prediction
accuracy. SVR allows mapping to high-dimensional spaces using kernel functions,
good for solving nonlinear problems. Grain yield datasets generally have small
sample sizes and many features, making SVR a promising… More >
