This study investigated the application of neural networks for detecting rectal tumor regions in patients using computed tomography (CT) images. The study included 138 patients, while two CT scans with a healthy rectum were included to balance the dataset, resulting in a total of 3566 images. For each image, pixel values along the contour and withi...

The paper presents an insight into the mathematical basis of fuzzy linguistic modeling and discusses the sensitivity of fuzzy rule-based systems with respect to membership function parameters, rule structure, and inference mechanisms. Examples with different inference models are analyzed and compared in order to illustrate their influence on the be...

The subject of this paper is a combined integer-valued autoregressive time series model with both positive and negative values, constructed by means of a new thinning operator. The proposed model can be regarded as a precursor of random environment integer-valued INAR models with state space on the entire set , providing a flexible framework for mo...
