Abstract:

Where should a researcher conduct experiments to provide training data for a multilayer perceptron? This question is investigated, and a statistical method for selecting optimal experimental design points for multiple output multilayer perceptrons is introduced. Multiple class discrimination problems are examined using a framework in which the multilayer perceptron is viewed as a multivariate nonlinear regression model. Following a Bayesian formulation for the case where the variance-covariance matrix of the responses is unknown, a selection criterion is developed. This criterion is based on t

Perceptron Architecture Ensuring Pattern Description CompactnessThis paper examines conditions a neural network has to meet in order to ensure the formation of a space of features satisfying the compactness hypothesis. The formulation of compactness hypothesis is defined in more detail as applied to neural networks. It is shown that despite the fact that the first layer of connections is formed randomly, the presence of more than 30 elements in the middle network layer guarantees a 100% probability that the G-matrix of the perceptron will not be special.

Co-processing (CP) provides superior properties to excipients and has become a reliable option to facilitated formulation and manufacturing of variety of solid dosage forms. Development of directly compressible formulations with high doses of poorly flowing/compressible active pharmaceutical ingredients, such as paracetamol, remains a great challenge for the pharmaceutical industry due to the lack of understanding of the interplay between the formulation properties, process of compaction, and stages of tablets’ detachment and ejection.

This paper proposes a complete procedure for the extraction and recognition of human faces in complex scenes. The morphology-based face detection algorithm can locate multiple faces oriented in any direction. The recognition algorithm is based on the minimum classification error (MCE) criterion. In our work, the minimum classification error formulation is incorporated into a multilayer perceptron neural network. Experimental results show that our system is robust to noisy images and complex background.

Obviously, if the printer input equals the scanner output, then there are no color errors involved in the entire system. In other words, the plant

The structure of the model results from two components, the neural network (NN) deterministic component and a random component which is assumed to be normally distributed. It is from this second component that the model achieves the ability to incorporate effectively the uncertainty associated with hydrological processes, making it valuable as a practical tool for synthetic generation of streamflow series.

Abstract:

Development of drug delivery systems for chronic disorders needs a complex thinking in order to ensure the quality of the product. A multidisciplinary approach of pharmaceutical technology, regulatory and behavioral sciences on the basis of the Quality by Design methodology can be a proper tool for this to handle formulators’, patients’, and also doctors’ needs in therapy planning in case of chronic ophthalmologic disorders. According to the present state-of-the-art”, patient perceptions are collected in the form of the “Patient Reported Outcome Measurements” during the clinical trials, but no

Abstract:

A detailed analysis of the spectra and frequencies of tones produced on metallophones in a Balinese orchestra clarifies a number of issues that arise in studying timbre and tuning. Among these are the relative importance of accuracy and completeness of measurements, the relevance of acoustical description to musical perception and style, the appropriateness of statistical generalizations and numerical formulations to musical practice and theory, and the possibility of bi-musical responses to divergent tuning systems. Byproducts of the investigation include a proposed basis for inter-cultural e

Abstract:

The utility perceived by individuals is believed to be different from the utility experienced by that individual. System dynamicists implicitly categorize this phenomenon as a form of bounded rationality, and traditionally employ an exponential smoothing function to capture it. We challenge this generalization by testing it against an alternative formulation of utility perception that is suggested by modern theories of behavioral sciences. In particular, the traditional smoothing formulation is compared with the peak–end rule in a simple theoretical model as well as in a medium-size model of e

Abstract:

AbstractDecades of research have established the direct influence of partisanship on voter perception of a host of real-world conditions. Even so, numerous factors have been found to moderate this “partisan bias.” We examine one plausible moderator: the volume of perceptually relevant information that is available in the mass media. Both dissonance-theoretic and motivated-reasoning formulations of partisan bias in political perception suggest that the availability of perceptually relevant information may constrain perceptual bias. Yet this proposition has rarely been investigated systematicall

Abstract:

One of the new trends of personal care industry is the use of organic ingredients derived from nature, in particular, from food-processing residues with proven efficacy. Lycopene is a carotenoid responsible for the red color of several fruits, namely tomato, whose antioxidant and photoprotective effects have been studied. Methods: Lycopene-enriched extracts (LEE) were obtained from tomato waste using supercritical CO2 extraction, incorporated in microemulsions and macroemulsions for topical use, and characterized through GC-MS for the identification of volatile compounds.

The article first presents and analyses the sources of two most frequently used indicators to measure corruption perceptions – the Corruption Perception Index and the Control of Corruption, one of the Worldwide Governance Indicators.

Abstract:

Plant proteins have been proposed as an alternative to animal-origin proteins in the wine industry because they are allergen-free and vegan-friendly. The aim of this study was to evaluate the effectiveness of plant proteins as fining agents on red wines with different phenolic composition. Two formulations for commercially available vegetal proteins (potato and pea origin) were assessed at two doses to modulate the fining treatment to the wine phenolic profile. The results evidenced that fining agents derived from plants have different levels of effectiveness on the removal of phenolic compoun

A common practice to account for psychophysical biases in vision is to frame them as consequences of a dynamic process relying on optimal inference with respect to a generative model. The study presented here details the complete formulation of such a generative model intended to probe visual motion perception with a dynamic texture model. It is derived in a set of axiomatic steps constrained by biological plausibility. We extend previous contributions by detailing three equivalent formulations of this texture model. First, the composite dynamic textures are constructed by the random aggregati

It is performed an analysis of the causes and consequences of the crisis of classical cybernetics, created by N. Wiener and W. R. Anby. N. Viener has shown that the basis of the crisis is the exclusion from the consideration of the process of forming the goal of activity for physiological and cybernetic systems. However, the study of the crisis of classical cybernetics is conducted from the historical point of view. N. Wiener's opinion on the role of the goal of the cybernetic system in management processes is not taken into account. The main focus is on the study of information management and
