Software engineers require a large amount of data for building neural network-based software systems. The engineering of these data is often neglected, though, it is a critical and time-consuming activity. In this work, we present a novel software engineering approach for dataset augmentation using neural networks. We propose a rigorous process for generating synthetic data to improve the training of neural networks. Also, we demonstrate our approach to successfully improve the recognition of handwritten digits using conditional generative adversarial networks (cGAN). Finally, we shortly discuss selected important issues of our process, presenting related work and proposing some improvements. [less ▲]

Today, there is a high demand on intelligent systems (e.g chatbots, ob- ject decetors, translators, etc). Engineers have to develop these systems in a lots of di erent domains (e.g. medicine, nance, car industry). More- over, these intelligent systems are trained on data collected from these do- mains using an iterative training process. Et each training iteration, the parameters of such system are updated intuitivly based on the engineer's experience. However, gathering and labelling these data is very costly and time consuming. Moreover, the systems are often complex. It is recom- mended to have a strong mathematical background. Thus, engineers often design these systems based on their own experience and collected informa- tion about the system. We present the road towards a novel methodology, called SEMKIS, for the design ang generation of intelligent systems and synthetic learning data. We use the model-driven engineering approach in our methodology to specify and design our systems. We generate speci - cations, designs and implementation of our intelligent systems. We used the mathematical set theory to de ne the concepts for the speci cation of intelligent systems and data synthetis within a formal conceptual frame- work. The concepts have been used in a small executable illustration that focuses on the recognition of handwritten digits on a picture. The results show that our concepts are usable and that we reduce the complexitiy of specifying and designing intelligent systems. [less ▲]

Defining and managing teaching programs at universities or other institutions is a complex task for which there is not much support in terms of methods and tools. This task becomes even more critical when the time comes to obtain certifications w.r.t. official standards. In this paper, we present an on-going project called TESMA, whose objective is to provide an open-source tool dedicated to the specification and management (including certification) of teaching programs. An in-depth market analysis regarding related tools and conceptual frameworks of the project is presented. This tool has been engineered using a development method called Messir for its requirements elicitation and introduces a domain-specific language dedicated to the teachin [less ▲]

The definition and organisation of programs related to their courses of educational institutions is a very complex and exhaustive task. There is a demand for such a solution by the educational institutions, as they need a detailed program descriptions for students and instructors. This task gets even more complicated if these programs and courses needs to be certified according to some international learning standards. At the moment, the availability of such methods or tools is very limited, except for some ad-hoc guidelines, which are use by some few universities, e.g. the Cornell University. Most of the institutions (e.g. University of Luxembourg) allows the professor to us their own methods for specifying their courses. Hence, most of the institutions are sharing similar problems, but using their own defined methods (e.g. naming conventions for its programs). At an university, professors are working in various domains and using therefore their own methods for specifying their courses, which results often in an incomplete program and course description. Methods such as SWEBOK (Software Engineering Body of Knowledge) and CS2103 (Computer Science Curricula 2013) which are program certifications according to an international learning standard are almost not known and used. Thus, programs and courses from different institution cannot be compared, since there is no common structure and process for specifying them. In this master thesis, we present TESMA (Tool for Educational Specification Management and Assessment of teaching programs), a tool based on a domain-specific language, which is dedicated to the teaching domain, for specifying, managing, and assessing programs. The Messir (Scientific Approach to Requirements Engineering) development method has been used for defining the concept and the requirements of the tool. Our research concentrates on the domain-specific language (DSL) in order to define requirements and improving the quality of the DSL’s. We focus on the development of an intuitive and maintainable domain-specific language, usable by people coming from different domains, e.g. software engineers, natural sciences, social sciences, linguistic, and so on. This thesis describes the requirements, the concepts, the realisation, and implementation of the tool, which are based on a domainspecific language of high quality for specifying programs. The quality of our DSL is assessed by a complete used cases related to the University of Luxembourg. [less ▲]
