WebCommunity Detection Algorithms. One of the main areas of interest in the field of network analysis is the detection of the communities that exist within a given network. Over the years, a large number of techniques have been proposed by different authors. These different approaches have their own advantages and disadvantages: some methods … In recent years, Hyperspectral Imaging (HSI) has become a powerful source for reliable data in applications such as agriculture,remote sensing, and biomedicine. However, hyperspectral images are highly data dense and often benefit from methods to reduce thenumber of spectral bands while retaining the most … See more We used an in-greenhouse controlled HSI dataset of Kochia leaves in order to classify three different herbicide-resistance levels (herbicide … See more This repository contains the following scripts: 1. interBandRedundancy.py: Executes both the pre-selection and final selection method for a desired number of spectral bands. 2. … See more
