Published: June 2010

We propose a framework for expanding a given image using an interpolator that is trained in advance with training data, based on sparse bayesian estimation for determining the optimal and compact support for efficient image expansion. Experiments on test data show that learned interpolators are compact yet superior to classical ones.

Despite similar incidence rates, nationwide breast cancer mortality is 40% higher among non-Hispanic Black (NHB) than non-Hispanic White (NHW) women. The racial disparity persists even among women with early-stage disease, prognostically favorable subtypes, and indicators of high socioeconomic status and is not evenly distributed throughout the US. Understanding geographic differences may provide additional insight into the drivers of the disparity.

AI techniques are increasingly being used to identify individuals both offline and online. However, quantifying their effectiveness at scale and, by extension, the risks they pose remains a significant challenge. Here, we propose a two-parameter Bayesian model for exact matching techniques and derive an analytical expression for correctness (κ), the fraction of people accurately identified in a population.

With the decreasing and aging agricultural workforce, fruit harvesting robots equipped with higher degrees of freedom (DoF) manipulators are seen as a promising solution for performing harvesting operations in unstructured and complex orchard environments. In such a complex environment, guiding the end-effector from its starting position to the target fruit while avoiding obstacles poses a significant challenge for path planning in automatic harvesting. However, existing studies often rely on manually constructed environmental map models and face limitations in planning efficiency and computational cost.

Objective: Accurate preoperative evaluation of myometrial invasion (MI) is essential for treatment decisions in endometrial cancer (EC). However, the diagnostic accuracy of commonly utilized magnetic resonance imaging (MRI) techniques for this assessment exhibits considerable variability. This study aims to enhance preoperative discrimination of absence or presence of MI by developing and validating a multimodal deep learning radiomics (MDLR) model based on MRI.

Article Synopsis
  • This study introduces a new Bayesian method for identifying structural damage using a technique called Improved Elemental Modal Strain Energy Ratio (IEMSER) to create a more focused prior distribution.
  • The approach uses measured frequencies and mode shapes to develop the IEMSER indicator, which informs damage assessment and guides the Markov Chain Monte Carlo (MCMC) sampling to find accurate damage estimates.
  • Results from numerical tests on a steel truss bridge and modal data from an 18-story frame structure demonstrate that this method enhances the accuracy of damage identification by effectively utilizing prior information.
