In this paper the properties of t-Student significance test in time series modeling are discussed. In particular GARCH models are considered. Their special property is the volatility clustering effect. Apart from the classic GARCH process, tests were also carried out in the case of processes…

Digital technologies have grown in importance in education over time and have become even more relevant with the epidemiological context established by the COVID-19 pandemic, necessitating unexpected and profound changes in work organization. These changes, in educational institutions, have resulted in the widespread use of remote…

The article shows a problem of digital picture classification with the use of convolutional neural networks in a multiclass classification problem. It describes basic problems related to the classification of data sets with a very large number of classes, and basic picture preprocessing operations. It…

One of the most significant factors affecting supervised neural network training is the precision of the annotations. Moreover, the problem of inconsistent data annotations is an integral part of real-world supervised learning processes, concerning even annotations created by experts in the field. One practical example…

The Covid 19 pandemic became the catalyst for the digitization process when research laboratories equipped with state-of-the-art experimental facilities and analytical equipment became unusable for more than a year and a half. Teams of researchers, professors and students continued in the virtual environment the research…

In the presented paper, we describe the works over the speech recognition of infoline records in the Polish language. One of the difficulties with this kind of records, is the number of different speakers. In addition, utterances are often short or overlapping, which can provide…
