Training deep neural networks on large datasets containing high-dimensional data requires a amount of computation. A solution to this problem is data-parallel distributed training, where model replicated into several computational nodes that have access different chunks the data. This approach, however, entails high communication rates and latency because computed gradients need be shared among at every iteration. The becomes more pronounced in case there wireless between (i.e., due limited...

Atomistic structures of materials offer valuable insights into their functionality. Determining these remains a fundamental challenge in science, especially for systems with defects. While both experimental and computational methods exist, each has limitations resolving nanoscale structures. Core-level spectroscopies, such as x-ray absorption (XAS) or electron energy-loss spectroscopies (EELS), have been used to determine the local bonding environment structure materials. Recently, machine...

Compact convolutional neural networks (CNNs) have witnessed exceptional improvements in performance recent years. However, they still fail to provide the same predictive power as CNNs with a large number of parameters. The diverse and even abundant features captured by layers is an important characteristic these successful CNNs. differences this between their compact counterparts rarely been investigated. In CNNs, due limited parameters, are unlikely be obtained, feature diversity becomes...

Hoaxes are non malicious viruses. They live on deceiving human?s perception by conveying false claims as truth. Throughout history, hoaxes have actually able to influence a lot of people the extent tarnishing victim?s image and credibility. Moreover, wrong misleading information has always been distortion growth. Some were created in way that they can even obtain personal data convincing victims those required for official purposes. different from spams masquerade themselves through address...

Poor retrieval performance significantly degenerates users' experience of visual search, especially in mobile search. Ideally, users would like to be alerted when bad queries are present, which helps eliminate latency as well waste bandwidth, 3G wireless environment. In this paper, we propose a query prediction (v-QPP) approach predict the effectiveness. We employ latent dirichlet allocation (LDA)to derive topics from image database. From collection statistics, model query's specificity...

Federated learning performs collaborative training of deep models among multiple clients, safeguarding data privacy, security, and legal adherence by preserving locally. While the remains stored in client side, instead being shared with server other recent work has shown that can still be reconstructed local updates or gradients. Different defense techniques have been proposed to address this information leakage from gradient updates, including introducing noise gradients, performing...

Federated learning (FL) performs collaborative training of deep models among multiple clients, safeguarding data privacy, security, and legal adherence by preserving locally. Despite the benefits FL, its wider implementation is hindered communication overheads potential privacy risks. Transiting locally updated model parameters between edge clients servers demands high bandwidth, leading to latency internet infrastructure constraints. Furthermore, recent works have shown that malicious...
