Modern foundation models often undergo iterative ``bootstrapping'' in their post-training phase: a model generates synthetic data, an external verifier filters out low-quality samples, and the high-quality subset is used for further fine-tuning. Over multiple iterations, model's performance improves--raising crucial question: how should total budget on generation training be allocated across iterations to maximize final performance? In this work, we develop theoretical framework analyze...
With the rapid advancements in artificial intelligence (AI), 5G technology, and robotics, multi-sensor fusion technologies have emerged as a critical solution for achieving high-precision localization mobile robots operating within dynamic unstructured environments. This study proposes novel hybrid framework that combines Extended Kalman Filter (EKF) Recurrent Neural Network (RNN) to address challenges such sensor frequency asynchrony, drift accumulation, measurement noise. The EKF provides...
Abstract Accurate position information is crucial for unmanned aerial vehicles (UAV) to execute tasks. To balance the contradiction between payload and localization accuracy of rotary UAVs, a cooperative method UAV swarms based on factor graph model studied in this paper. Each equipped with local model. A distributed model-solving method, AGA-Gauss–Newton conjugate gradient (GNCG), which combines an adaptive genetic algorithm improved GNCG algorithm, proposed. The issue falling into optimal...
High resolution X-ray diffractometry (HR-XRD), Photoluminescence, Raman spectroscopy, and Transmission electron microscope measurements are reported for GaN deposited on a conventional Si(111) substrate the {111} facets etched Si(100) substrate. HR-XRD reciprocal space mappings showed that GaN(0002) plane is tilted by about 0.63° ± 0.02° away from exposed Si{111} growth surface patterned substrate, while no observable tilt existed between planes The ratio of integrated intensities yellow to...
An investigation was conducted on electron beam-welded and additively manufactured joints a thick-walled titanium alloy utilizing in situ laser beam deposition welding techniques. The surface morphology, microstructural characteristics, mechanical properties of both joint types were comprehensively analyzed using stereomicroscopy, scanning microscopy (SEM), microhardness tensile strength testing, backscatter diffraction (EBSD) electron-beam-welded exhibited distinct fusion heat-affected...
