Bounding the variance
WebMar 18, 2024 · Assuming they are all equal, and noting that the variance of a sum is the sum of the variances for independent variables (i.e. the independent increments), then we have that $$\sigma^2 = \sum_i \sigma_i^2 = \frac{1}{\Delta t} \sigma_i^2$$ which yields $$ \sigma_i^2 = \sigma^2 \Delta t ,$$ or equivalently $$ \sigma_i = \sigma \sqrt{\Delta t ... WebInstead of predicting directly the coordinates of the object center on the image plane, we use cues from the 2D bounding box prediction and we predict the offset position in pixels of the object center from the 2D bounding box center c ˜ = c x ˜ c y ˜. We are therefore reducing the variance of the prediction, making it easier for the ...

WebNov 22, 2024 · A lack of variance bounding can be seen in terms of the chain struggling to leave a certain region, which typically has a low probability under \(\pi\). In practice, this lack of variance bounding (or a lack of geometric ergodicity) can manifest in two ways. 1. Web2 days ago · Synthetic Aperture Radar (SAR) is an all-weather sensing technology that has proven its effectiveness for ship detection. However, detecting ships accurately with oriented bounding boxes (OBB) on SAR images is challenging due to arbitrary ship orientations and misleading scattering. In this article, we propose a novel anchor-free key-point-based …

Although our bounds are similar to bounds of supervised learning, there are some notable dif-ferences. In regression estimation, the approximation power of the function set is usually measured
