CoCalc as a Learning Tool for Neural Network Simulation in the Special Course "Foundations of Mathematic Informatics"

The role of neural network modeling in the learning content of the special course "Foundations of Mathematical Informatics" was discussed. The course was developed for the students of technical universities - future IT-specialists and directed to breaking the gap between theoretic computer science and it's applied applications: software, system and computing engineering. CoCalc was justified as a learning tool of mathematical informatics in general and neural network modeling in particular. The elements of technique of using CoCalc at studying topic "Neural network and pattern recognition" of the special course "Foundations of Mathematic Informatics" are shown. The program code was presented in a CoffeeScript language, which implements the basic components of artificial neural network: neurons, synaptic connections, functions of activations (tangential, sigmoid, stepped) and their derivatives, methods of calculating the network's weights, etc. The features of the Kolmogorov-Arnold representation theorem application were discussed for determination the architecture of multilayer neural networks. The implementation of the disjunctive logical element and approximation of an arbitrary function using a three-layer neural network were given as an examples. According to the simulation results, a conclusion was made as for the limits of the use of constructed networks, in which they retain their adequacy. The framework topics of individual research of the artificial neural networks is proposed.Comment: 16 pages, 3 figures, Proceedings of the 13th International Conference on ICT in Education, Research and Industrial Applications.

On the Information Engine of Circuit Design

This paper addresses a new approach to find a spectrum of information measures for the process of digital circuit synthesis. We consider the problem from the information engine point of view. The circuit synthesis as a whole and different steps of the design process (an example of decision diagram is given) are presented via such measurements as entropy, logical work and information vitality. We also introduce new information measures to provide better estimates of synthesis criteria. We show that the basic properties of information engine, such as the conservation law of information flow and the equilibrium law of information can be formulated.Comment: 4 pages, 1 figure, 2 tables, MWSCAS'0

Young adults' perceptions of the implications of their hereditary, visual impairment: A Cape Town based study

In South Africa, approximately 600 000 individuals are visually impaired. Approximately onethird of genetic disorders and syndromes involves the eye, including conditions such as congenital cataracts, glaucoma, albinism, and retinal degenerative disorders. The transition into adulthood of visually disabled individuals is a crucial time, as it lays the foundation for their future. The aim of this research was to explore the level of understanding, perceptions and lived experiences of young adults aged eighteen to twenty-three who are visually impaired due to a genetic cause. A qualitative design, utilizing a phenomenological approach was used for this study. Fifteen participants were recruited through Athlone School for the Blind, the League of Friends of the Blind and Retina SA. In-depth interviews were conducted and data obtained was analysed using thematic analysis. Five themes were identified through this approach indicating the implications of having a genetic visual condition as perceived and experienced by these young adults. Most of the young adults experienced difficulty in understanding their condition and the genetic bases thereof and they had a strong desire to obtain clarity and knowledge via genetic counselling. The community was thought not to understand their situation either. They were unsure of the inheritance risks to future offspring and some indicated that they felt that this was a gamble they were unwilling to take, whilst others would have children. In some instances, their own visual impairment might create obstacles to raising children. Social interactions were greatly impacted and they felt isolated and tried to avoid unpleasant treatment, stigmatization and pity from the community. Intimate relationships were also noted as a challenge. Mobility is a major obstacle due to the incapacity to drive, as well as the lack of disability user-friendly public transportation and a daunting environment. They want to and feel that they can be independent and achieve the same things as sighted individuals, but society and life circumstances often create barriers to this. This research could assist in providing information to create more efficient, patient-centred genetic services and might be informative to various organizations about targeted support to provide these individuals and methods to assist their transition to adulthood
