oLMpics - On what Language Model Pre-training Captures

Recent success of pre-trained language models (LMs) has spurred widespread interest in the language capabilities that they possess. However, efforts to understand whether LM representations are useful for symbolic reasoning tasks have been limited and scattered. In this work, we propose eight reasoning tasks, which conceptually require operations such as comparison, conjunction, and composition. A fundamental challenge is to understand whether the performance of a LM on a task should be attributed to the pre-trained representations or to the process of fine-tuning on the task data. To address this, we propose an evaluation protocol that includes both zero-shot evaluation (no fine-tuning), as well as comparing the learning curve of a fine-tuned LM to the learning curve of multiple controls, which paints a rich picture of the LM capabilities. Our main findings are that: (a) different LMs exhibit qualitatively different reasoning abilities, e.g., RoBERTa succeeds in reasoning tasks where BERT fails completely; (b) LMs do not reason in an abstract manner and are context-dependent, e.g., while RoBERTa can compare ages, it can do so only when the ages are in the typical range of human ages; (c) On half of our reasoning tasks all models fail completely. Our findings and infrastructure can help future work on designing new datasets, models and objective functions for pre-training.
DIDACTIC CONDITIONS OF INTERNET TECHNOLOGIES APPLICATION IN THE EDUCATIONAL ENVIRONMENT OF GENERAL SECONDARY EDUCATION INSTITUTIONS

It is analyzed the concept of "didactic conditions", it is also offered its own definition of the concept in the article. It was found that in most pedagogical sources this issue is studied within higher education establishments, so our paper is devoted to general secondary education. Four main pedagogical conditions for the use of Internet sources in the educational environment are identified. They are technical equipment for computerized education, combination of information and communication technologies with traditional forms of education, teacher training to use innovations in the educational process through appropriate applied training, as well as the formation of a high level of digital skills of secondary school students. Attention is also paid to fleeting, auxiliary didactic conditions. This is a combination of activity and competence approaches to learning, activation of educational and cognitive activities of students through game learning, visualization of educational material, increasing the motivational aspect of learning through the novelty of teaching methods; providing a positive emotional background of learning, online support of students outside the school in order to motivate, adjust, direct work. It was found that for the formation of any didactic condition (basic or auxiliary), there must be a number of factors - the reasons for its appearance. The formation of didactic conditions is a long-term process that is the result of solving a didactic problem. The essence of the didactic condition itself is inconsistent, which is associated with the development of society, its constant changes. Similarly, the set of didactic conditions also constantly varies: one condition becomes irrefutable, does not require proof, but a new, more urgent or relevant one appears.Big part of the article is devoted to the analysis of modern Internet resources for teachers to master computer technology, mastering the skills of using gadgets in the educational space.

Security Assessment Using Nessus Tool to Determine Security Gaps on the Repository Web Application in Educational Institutions

This research aims to determine security holes and risks that may arise in the educational institution’s repository web application. The repository web application contains research data, journals, articles, and papers from lecturers and students at the institution. This web application does not yet have documentation about security holes and risks in it. It causes a sense of concern on the part of educational institutions. Therefore, it is necessary to have a security assessment to conduct a risk-oriented assessment that might occur if an attack is attempted. The Vulnerability Assessment and Penetration Testing (VAPT) method was utilized to conduct a security assessment and test educational institutions’ repository web application. Several vulnerabilities found with the Nessus tool could still be exploited and resulted in findings in legal access rights when the researchers performed a test simulation on the repository web application. This research was used as a report to the educational institution, particularly as a material for the evaluation process to increase its web application security. This research was carried out within the educational institution environment. Hence, it did not fully describe the possibility of actual attacks originating from outside the educational institution environment.

Pendampingan Dan Pelatihan Desain Grafis Untuk Kewirausahaan Bagi Siswa SMK Muhammadiyah 9 Wagir

The problem faced by students is at the production stage, namely the problem of product labeling. Until now labeling was done simply or without labeling. If students can design their own product labels, of course this will add to the selling value of the product. The existence of labels and brochures also add value to the promotion of student products. The aim of this mentoring activity is to provide training and graphic design assistance to students of SMK. The steps of this community service activities are observations, socialization, graphic design training, assistance in making labels and brochures for student entrepreneurial products, as well as evaluating and reflecting on service activities. The result of this service activity was in the form of training and graphic design assistance for students. All of the activities was well done . This can be seen from the number of students who participated in training and mentoring for three days. In addition, there are positive responses from teachers and students that have an impact on the success of this graphic design training and assistance. This can be seen from the results of student designs that are attractive and can be used as a commercial tool.

Perbandingan Metode Bootstrap, Jacknife Jiang Dan Area Specific Jacknife Pada Pendugaan Mean Square Error Model Beta-Bernoulli

Small area estimation is defined as a statistical technique for estimating the parameters of a subpopulation with a small sample size. One method of estimating small area parameters is the Empirical Bayes (EB) method. The accuracy of the Empirical Bayes (EB) estimator can be measured by evaluating the Mean Squared Error (MSE). In this study, 3 methods to determine MSE in the EB estimator of the Beta-Bernoulli model will be compared, namely the Bootstrap, Jackknife Jiang and Area-specific Jackknife methods. The study is carried out theoretically and empirically through simulation with R-studio software version 1.2.5033. The simulation results in a number of areas and pairs of prior distribution parameter values, namely Beta, show the effect of sample size and parameter value pairs on the Mean Square Error (MSE) value. The larger the number of areas and the smaller the initial 𝛽, the smaller the MSE value. The area-specific Jackknife method produces the smallest MSE in the number of areas 100 and the Beta parameter value 0.1.

Why do we digitize books instead of knowledge?

Besides text and images, contemporary e-books can include multimedia, interactivity, pronunciation information and text-to-speech ready content. The current EPUB 3 standard provides all the technical solutions necessary for designing and displaying highly functional and content rich e-books, but the implementation is impaired by the e-reader industry, publishers and distributors. Local and global book digitization has been an ongoing process for years, encompassing publications ranging from classical literature to current technical textbooks. Textual expression of knowledge is a remnant of the past but it is still dominant today, even though interactivity and video content are known to significantly enhance the learning process. However, multimedia and interactive content for e-books is not produced because it requires time, technical knowledge and specific tools. Within the current publishing system, authors are expected to produce and design all the content for books on their own, but because of the extreme content diversity, it is unrealistic to expect that they really possess such knowledge and skills. Better collaboration among authors, publishers, distributors, the professional community and the related industry is necessary for knowledge digitization to function.
