Frequency warping based on two factor weighted fusion

2017

Traditional frequency warping algorithms in speech recognition mainly consider the spectrum offset caused by different vocal tract length. But in addition to the vocal tract length, the pronunciation diversity is also affected by the glottis …

MetaLDA: A Topic Model that Efficiently Incorporates Meta Information

2017

Besides the text content, documents and their associated words usually come with rich sets of meta information, such as categories of documents and semantic/syntactic features of words, like those encoded in word embeddings. Incorporating such …

Cooperative Space Object Tracking Based on Distributed Adaptive Variational Bayesian Cubature Kalman Filter

2018 · 2018 IEEE CSAA Guidance, Navigation and Control Conference (CGNCC)

In this paper, we investigate noise covariance adaptive distributed Bayesian filter based on variational Bayesian method. In Bayesian filter framework, the joint distribution of state and noise covariance is approximated by variational Bayesian (VB) method, …

P4NIS: Improving network immunity against eavesdropping with programmable data planes

2020

Due to improving computational capacity of supercomputers, transmitting encrypted packets via one single network path is vulnerable to brute-force attacks. The versatile attackers secretly eavesdrop all the packets, classify packets into different streams, performs an …

Restoration method of DC ground potential distribution law based on neural network

2020

DC Surface Potential (DCESP) distribution is the key to DC bias in power system transformers. Unbalanced or unipolar operation of the HVDC transmission system, and the stray current of the rail transit traction power supply …

A pseudo Karnaugh mapping approach for datasets imbalance

2021 · E3S Web of Conferences

The problem of dataset imbalance has raised a wide concern in many machine learning areas, but not in non-intrusive load monitoring, or load disaggregation. In this study, a pictorial evaluation method is proposed to representation …

Power Data Blockchain Sharing Scheme based on Homomorphic Encryption

2022 · 2022 IEEE 5th Advanced Information Management, Communicates, Electronic and Automation Control Conference (IMCEC)

In the process of cross-agency flow of power data, only sharing the results of the operational analysis of power data rather than the source data is an effective sharing method that can not only meet …

A survey of security threats in federated learning

2025 · Complex & Intelligent Systems

Federated learning is a distributed machine learning paradigm that emerged as a solution to the need for privacy protection in artificial intelligence. Like traditional machine learning, federated learning is threatened by multiple attacks, such as …
