fuzzy rule-based classification systems (frbcs) are highly investigated by researchers due to their noise-stability and interpretability. unfortunately, generating a rule-base which is sufficiently both accurate and interpretable, is a hard process. rule weighting is one of the approaches to improve the accuracy of a pre-generated rule-base without modifying the original rules. most of the pro...
The main objective of this paper is to use a computational intelligence algorithm for preparing a mapping map that categorizes different patterns of identification of infected areas and changes in radiation pollution. In this paper, the use of the fuzzy inference system has been proposed to determine the degree of radiation contamination in the regions. The study uses ultra-high resolution spec...
The capability of the matter identification is developed considerably in hyperspectral images. The spectral reflectance of surfaces in these imaging systems in the visible and near infrared range of the electromagnetic spectrum is recorded in extremely narrow and continuous bands. But for some reasons, such as existence the mixed pixels and low spatial resolution of these images, is difficult t...
We propose a new method for the construction of nearest prototype classifiers which is based on a Gaussian mixture ansatz and which can be interpreted as an annealed version of learning vector quantization (LVQ). The algorithm performs a gradient descent on a cost-function minimizing the classification error on the training set. We investigate the properties of the algorithm and assess its perf...
Medial collateral ligament (MCL)injury, is one of the most common ligament injuries of the knee,mostly results from a valgus force.Restoration of function and going back to the pre-injury level of function is the aim of treatment in ligament injuries of the knee. There are multiple soft tissue structures in medial side that play an important role in connection with each other to retain medial s...
Classification of drugs has no long history. Many modern countries in recent decades classified different types of drugs in their judicial and legal criminal policy. The most popular classification in this respect is soft and hard drugs. The Netherlands was the pioneer in this respect. As the experiences show the third type named hybrid drugs can be known. One of the most important results of d...
This paper outlines the changes necessary to convert the iterative guided spectral class rejection (IGSCR) classification algorithm to a soft classification algorithm. IGSCR uses a hypothesis test to select clusters to use in classification and iteratively refines clusters not yet selected for classification. Both steps assume that cluster and class memberships are crisp (either zero or one). I...
Examining most streaming clustering algorithms leads to the understanding that they are actually incremental classification models. They model existing and newly discovered structures via summary information we call footprints. Incoming data is normally assigned a crisp label (into one of structures) structure's footprint incrementally updated. There no reason these assignments need be crisp. I...
Noise present in the digital mammograms directly influences the capability and competence of a classification task which makes de-noising a challenging problem. In the literature, few wavelets like daubechies db3 and haar have been used for de-noising medical images. Nevertheless, wavelet filters such as sym8, dB3, dB4, haar and Coif1 at certain level of soft and hard threshold functions have n...
