The main goal of any classification or regression task is to obtain a model that will generalize well on new, previously unseen data. Due to the recent rise of deep learning and many state-of-the-art results obtained with deep models, deep learning architectures have become one of the most used model architectures nowadays. To generalize well, a deep model needs to learn the training data well without overfitting. The latter implies a correlation of deep model optimization and regularization with generalization performance. In this work, we explore the effect of the used optimization algorithm and regularization techniques on the final generalization performance of the model with convolutional neural network (CNN) architecture widely used in the field of computer vision. We give a detailed overview of optimization and regularization techniques with a comparative analysis of their performance with three CNNs on the CIFAR-10 and Fashion-MNIST image datasets.
Ovaj rad sadrži teorijsko istraživanje metoda i elemenata transformacije prostora, referentnih primera urbanih transformacija napuštenih pruga kao i predlog transformacije napuštene pruge Beočin – Petrovaradin. Cilj predloženog urbanističkog rešenja je davanje novog značaja i funkcije ovoj pruzi u vidu zelenog koridora, kao i nastanak raznih sadržaja koji bi privlačili stanovnike, ali i posetioce iz šireg okruženja bez obzira na pol, godine i interesovanja.
This paper points out the relationship of influences and key aspects of the implementation of ICT in the study with students, future preschool teachers, that largely affects the students' expansion of general and professional competencies at the Preschool Teachers' Training College in Kikinda. The research was conducted in the period from October to November 2014, Likert questionnaires were used, and 300 students from the first to the third year of study were interviewed. By analyzing of results, four key aspects can be observed regarding students' communication relationships with Preschool Teachers' Training College in Kikinda, their communication relationship with colleagues, their communication with colleagues outside the Republic of Serbia and their communication with many educational institutions and professional associations. It is concluded that the use of advanced information and communication technologies is, mostly, an essential need for students to upgrade professional competencies that greatly influences the effects of expanding knowledge in order to integrate theory and practice. Results indicate that the effects of the use of information and communication technologies influence the students` capacities to increase the correlations between the formal and informal aspects of education, between primary institutions for preschool teachers education - Preschool Teachers' Training College in Kikinda of and numerous professional elite groups: governmental and non-governmental organizations, institutes, colleges and kindergartens. Also, the results of the questionnaire created for research use of information and communication technologies, confirm the hypothesis that the use of new information and communication technologies certainly influence the process of building quality study, and later easily find an employment in the upbringing and education fields.
This paper points to the relations of influence and key aspects of the use of different media during studies among students, future teachers, at the College of Professional Studies in Education of Teachers in Kikinda and the State University of Novi Pazar, which largely affect the culture of speech but also the expansion of general and professional competencies of students. The paper analyzes the influence of television and new media in the development of speech culture, where we highlight the importance of complementarity between books as media and new media, as well as their potential that can take advantage of the development of speech culture of students - future teachers. The research was conducted during the period from September to November 2015. The questionnaire, with coverage of 300 students from first to third year of the University College of Professional Studies in Education of Teachers in Kikinda and 100 students from first to fourth year of the State University of Novi Pazar. The conclusion is that young people are preoccupied with the modern media (internet, social networks) that the brevity of expression in e-mails, and text messages significantly affects the research, as waste of time in so-called social media. Students - future educators, are using modern media in the process of informal learning and entertainment, which to a large extent forms the negative attitude towards printed media - the book and leads to the impoverishment of the lexis and to the low level of speech culture and speech which represents the basis of all educators. The paper confirms that the essential ways of using the media, as well as the expressive power of modern media have a strong influence on the speech culture of students - future teachers, but also to their education and general culture. The paper confirms that the ways of using the media are of essential value, as well as that the expressive power of modern media has a strong influence on the speech culture of students - future teachers, but also to their education and general culture. Using modern media confirms the hypothesis that the media negatively affects speech culture of students - future teachers, with the possibility of appearance of pseudo communication and socialization, and confirms the influence of modern media in the creation of prejudices and stereotypes, but also to creates a distorted image of reality.
