In the standard quantum theory, causal order of occurrence between events is prescribed, and must be definite. This has been maintained in all conventional scenarios operation for batteries. this study we take a step further to allow charging batteries an indefinite (ICO). We propose nonunitary dynamics-based protocol experimentally investigate using photonic switch. Our results demonstrate that both amount energy charged thermal efficiency can boosted simultaneously. Moreover, reveal...

Sequential incentive marketing is an important approach for online businesses to acquire customers, increase loyalty and boost sales. How effectively allocate the incentives so as maximize return (e.g., business objectives) under budget constraint, however, less studied in literature. This problem technically challenging due facts that 1) allocation strategy has be learned using historically logged data, which counterfactual nature, 2) both optimality feasibility (i.e., cost cannot exceed...

Description methods based on interest points and Bag-of-Words (BOW) model have gained remarkable success in human action recognition. Despite their popularity, the existing point detectors always come with high computational complexity lose power when camera is moving. Additionally, vector quantization procedure BOW ignores relationship between bases large reconstruction errors. In this paper, a spatio-temporal detector flow vorticity used, which can not only suppress most effects of motion...

Modelling the user's multiple behaviors is an essential part of modern e-commerce, whose widely adopted application to jointly optimize click-through rate (CTR) and conversion (CVR) predictions. Most existing methods overlook effect two key characteristics behaviors: for each item list, (i) contextual dependence refers that on any are not purely determinated by itself but also influenced previous (e.g., clicks, purchases) other items in same sequence; (ii) time scales means users likely...

With the rise of smart devices, there is an escalating need for lightweight methods in human pose estimation (HPE). Although existing 2D HPE techniques have demonstrated impressive performance on public datasets, they still suffer from high model complexity and latency issues practical applications. To address challenge, this paper proposes a novel approach HPE. By utilizing shuffle blocks instead traditional ResNet, we significantly reduce size computational requirements. Moreover, our...

Manually annotating datasets for training deep models is very labor-intensive and time-consuming. To overcome such inferiority, directly leveraging web images to conduct data becomes a natural choice. Nevertheless, the presence of label noise in usually degrades model performance. Existing methods combating are typically designed tested on synthetic noisy datasets.

In this paper, Sparse Coding with Non-negative and Locality constraints (SCNL) is proposed to generate discriminative feature descriptions for human action recognition. The non-negative constraint ensures that every data sample in the convex hull of its neighbors. locality makes a only represented by related neighbor atoms. sparsity confines dictionary atoms involved representation as fewer possible. SCNL model can better capture global subspace structures than classical sparse coding, are...
