With the growth of information technology there is a greater need of high security, so biometric authentication systems are gaining importance. Face recognition is more used because it’s easy and non intrusive method during acquisition procedure. Various methods are used for facial recognition. Principal component analysis (PCA) based systems are used often. In this paper we study 4 distance me...

morphophysiological variations of field bindweed populations in tehran province was studied during 2006 and 2007 growing seasons using multivariate analysis methods. to determine the variations, 43 morphological and physiological characters were considered biometrically.  the main characters at principal component analysis (pca) consisted of leaf dry weight, shoot dry weight, and leaf area to i...

In this paper, we propose a new classification technique based on the Minimum Component Analysis (MCA) instead of the traditional Principal Components Analysis (PCA). Most existing classification techniques based on PCA represent a class by its principal component. However, the principal component is not always the best choice since there is a high possibility for classes to overlap with each o...

Meat, as an important source of protein, is one of the main parts of many people’s diet. Due toeconomic interests and thereupon adulteration, there are special concerns on its accurate labeling.In this study Fourier transform infrared (ATR-FTIR) spectroscopy combined with chemometrictechniques (principal component analysis (PCA), artificial neural networks (ANNs), and partial<...

Autoencoders and generative models produce some of the most spectacular deep learning results to date. However, understanding controlling latent space these presents a considerable challenge. Drawing inspiration from principal component analysis autoencoders, we propose autoencoder (PCA-AE). This is novel whose verifies two properties. Firstly, dimensions are organised in decreasing importance ...

Extra virgin olive oil samples were collected from different geographical areas of Central Dalmatia region in Croatia including locations both on the coast and islands. This set included 41 oils of cultivar Oblica, 1 per cultivars Coratina and Leccino, and 5 of mixed cultivars Lastovka and Oblica. Attenuated total reflectance (ATR) spectra of non-treated samples were recorded and principal comp...

Maximum management of the library, especially improving services to users is a must that needs be evaluated by library manager. Visitor satisfaction difficult measure because it relates high and low expectations visitors service they want. The purpose this study investigate most important factors or components in aspects visitor satisfaction. So can increase appropriately so carry out right str...

A new meta-heuristics is introduced here: the Multi-Particle Collision Algorithm (M-PCA). The M-PCA is based on the implementation of a function optimization algorithm driven for a collision process of multiple particles. A parallel version for the M-PCA is also described. The complexity for PCA, M-PCA, and a parallel implementation for the MPCA is developed. The efficiency for optimization for...
