2024年10月15日 · Based on 7 years (2015–2021) of capture-mark-recapture of carrion crows (Corvus corone) in the city of Paris, France, we used multi-state models to examine the intra-annual (3-month time steps)...

Corvidae is a cosmopolitan family of oscine passerine birds that contains the crows, ravens, rooks, magpies, jackdaws, jays, treepies, choughs, and nutcrackers. [1][2][3] In colloquial English, they are known as the crow family or corvids. Currently, 139 species are included in this family.

This study proposes an integrated method for selecting the optimal deep learning model based on a novel crow swarm optimization algorithm for COVID-19 diagnosis. The crow swarm optimization is employed to find an optimal set of coefficients using a designed fitness function for evaluating the performance of the deep learning models.

2023年8月1日 · The suggested encouragingly high classification performance suggests that it can effectively automate COVID-19 identification from radiography images to deliver quick and accurate proof of COVID-19 disease in the lungs that can be used to supplement current COVID-19 test material.

2023年3月1日 · In this paper, we propose an improved crow search algorithm (CSA) based on variable neighborhood descent (VND) and information exchange mutation (IEM) strategies, called VMCSA. The original CSA quickly falls into the local optimum, and the possibility of finding the best solution is significantly reduced.

2022年2月1日 · Experiments on the COVID-19 disease dataset in a Brazilian hospital show that the crow learning algorithm reduces the feature selection objective function by iteration. Decreasing the feature...

2023年3月1日 · The target area is extracted from the X-ray images by image segmentation to improve classification efficiency and help doctors make a diagnosis. In this paper, we propose an improved crow search algorithm (CSA) based on variable neighborhood descent (VND) and information exchange mutation (IEM) strategies, called VMCSA.

2023年3月3日 · To date, chest X-rays images play a crucial part in the diagnosis of COVID-19; the resultant X-ray images are extracted as normal images and are segmented into small regions with different information, some of which may contain features of COVID-19, and this process is commonly referred to as the image segmentation (IS) problem (Amyar et al ...
