In this paper, we propose a single-shot instance segmentation method, which is simple, fast and accurate. There are two main challenges for one-stage segmentation: object instances differentiation pixel-wise feature alignment. Accordingly, decompose the into parallel subtasks: Local Shape prediction that separates even in overlapping conditions, Global Saliency generation segments whole image pixel-to-pixel manner. The outputs of branches assembled to form final masks. To realize that, local...

The task of Vision-Language Navigation (VLN) is for an embodied agent to reach the global goal according instruction. Essentially, during navigation, a series sub-goals need be adaptively set and achieved, which naturally hierarchical navigation process. However, previous methods leverage single-step planning scheme, i.e., directly performing action at each step, unsuitable such In this paper, we propose Adaptive Zone-aware Hierarchical Planner (AZHP) explicitly divides process into two...

Time-domain topology optimization is used here to design optical pulse-shaping filters in Si/SiO2 thin-film systems. A novel envelope objective function as well explicit penalization are adapt the method this unique class of problems.

The slow light coupling efficiency in photonic crystal waveguides is enhanced by using the topology optimisation method. As much as 5 dB improvement transmission can be achieved proximity of spectrum cutoff. Moreover, resemblance resulting two optimised spectra from different initial configurations indicates possible convergence optimisations.

Shell vibration signals generated during grinding have useful information related to ball mill load, while usually contaminated by noises. It is a challenge recognize load parameters with these signals. In this paper, novel approach proposed based on the improved empirical wavelet transform (EWT), refined composite multi-scale dispersion entropy (RCMDE) and fireworks algorithm (FWA) optimized SVM. Firstly, are denoised EWT, which uses cubic spline interpolation calculate envelope spectrum...
