Latent Semantic and Disentangled Attention.

Sequential learning using transformer has achieved state-of-the-art performance in natural language tasks and many others. The key to this success is the multi-head self attention which encodes and gathers the features from individual tokens of an input sequence. The mapping or decoding is performed to produce an output sequence via cross attention. There are threefold weaknesses by using such an attention framework. First, since the attention would mix up the features of different tokens in input and output sequences, it is likely that redundant information exists in sequence data representation. Second, the patterns of attention weights among different heads tend to be similar. The model capacity is bounded. Third, the robustness in an encoder-decoder network against the model uncertainty is disregarded. To handle these weaknesses, this paper presents a Bayesian semantic and disentangled mask attention to learn latent disentanglement in multi-head attention where the redundant features in transformer are compensated with the latent topic information. The attention weights are filtered by a mask which is optimized through semantic clustering. This attention mechanism is implemented according to Bayesian learning for clustered disentanglement. The experiments on machine translation and speech recognition show the merit of Bayesian clustered disentanglement for mask attention.

Pengaruh Model Pembelajaran Inkuiri Terbimbing Terhadap Hasil Belajar Siswa Pada Mata Pelajaran Informatika Di SMK

The learning process has an influence in achieving significant learning outcomes, including learning media, learning motivation and learning models, learning models are a learning plan that will take place which contains a learning design. The learning model refers to the learning method that will be used, including learning objectives, learning stages, learning environment, and classroom management. To improve learning outcomes, it is necessary to improve the model that influences learning outcomes, where the learning model greatly influences learning outcomes, this can improve learning outcomes significantly. In the learning that took place at the Antarctic 1 Sidoarjo school, there were students who were hyperactive and less conducive due to several things including students who did not like to be restrained and needed more attention to be able to implement conducive learning, in overcoming this problem, the researcher chose a guided inquiry learning model to improve learning outcomes, this is because this learning model is more fun with learning that is packaged in a question, which is able to improve students' understanding by asking questions to satisfy their curiosity, in implementing this model the researcher used the One Group Pretest Posttest research design, by giving the same treatment to a population with two meetings, starting with giving recognition to the Pretest and ending with the Posttest. Then the data is processed to see the effect of giving treatment in the population. Hypothesis testing using the paired t-test formula (T-Paired) produces a decision that is rejected H0, the calculation of the influence with the eta square test from the table of criteria results shows a large influence. It can be concluded that there is an influence on student learning outcomes in informatics subjects using the guided inquiry learning model.

Development of Video Learning Media Based on Robert Gagne's Theory (Nine Events of Instruction) in Informatics Subjects at Junior High School

One component that cannot be separated from the learning process is learning media. Learning media is an essential part of education, regardless of the curriculum, because it plays a crucial role in influencing the quality and success of learning. The Informatics subject is no exception, as it introduces computers to students. This introduction is the initial stage of informatics lessons. In presenting the learning process through computer application materials, good preparation is essential. An educator should do more than just coordinate students in front of the computer, use a loud voice to direct them, or write notes on the blackboard. They must wisely package the teaching materials to make learning enjoyable, allowing students to feel that the classroom is a place to explore while they learn to use a computer. This type of research is development and research (R&D) using the ADDIE model. Product validation tests were conducted by three validators: one material validator, one language validator, and one media validator. The product trial involved 30 seventh-grade students from SMPN 1 Siak Hulu, aimed at assessing the practicality of the developed product. The effectiveness test was conducted by administering pre-test and post-test questions to the students. The results of the video media development research showed a validation level of 86% for the material and 85% for the language, both falling into the very valid category. The product practicality results indicated a practicality level of 91%, also in the very practical category. The effectiveness test yielded a t-value of 16.4.

Topic aware probing: From sentence length prediction to idiom identification how reliant are neural language models on topic?

Abstract Transformer-based neural language models achieve state-of-the-art performance on various natural language processing tasks. However, an open question is the extent to which these models rely on word-order/syntactic or word co-occurrence/topic-based information when processing natural language. This work contributes to this debate by addressing the question of whether these models primarily use topic as a signal, by exploring the relationship between Transformer-based models’ (BERT and RoBERTa’s) performance on a range of probing tasks in English, from simple lexical tasks such as sentence length prediction to complex semantic tasks such as idiom token identification, and the sensitivity of these tasks to the topic information. To this end, we propose a novel probing method which we call topic-aware probing. Our initial results indicate that Transformer-based models encode both topic and non-topic information in their intermediate layers, but also that the facility of these models to distinguish idiomatic usage is primarily based on their ability to identify and encode topic. Furthermore, our analysis of these models’ performance on other standard probing tasks suggests that tasks that are relatively insensitive to the topic information are also tasks that are relatively difficult for these models.

Concept Development on Early Childhood Education: Awareness, Dialogic Inclusion and Practice

This review article concentrated solely on concept development in early childhood education. Children’s concept development is critical, and it serves as a foundation for perceiving topic information for improved learning in higher levels of schooling. This article proposes dialogic inclusion as a strategy to improve the effectiveness of early childhood education by helping children acquire concepts effectively. As a start-up, the present system of early childhood education was brushed up with its aims and criteria for meeting the key topics. Simultaneously, core concepts such as classification, patterning, structure, and reasoning were discussed in relation to their nature, and the existing teaching procedure for the aforementioned concepts in early childhood was thematically represented. The dialogic inclusion, its awareness, and the existing system of childhood education in India with regard to concept development were reviewed, and dimensions of concepts were paragraphed. The phase of ‘dialogic inclusion’ in concept formation in education at the early childhood level was then disclosed, along with the themes’ relevance.

Corporate bond default prediction using bilateral topic information of credit rating reports

The default of corporate bonds can result in large financial losses as well as irreparable harm to investors’ trust and the economy as a whole, which implies that the identification of corporate bond default must be done promptly and properly. Current studies mainly rely on accounting and/or macroeconomic data and use the credit rank (CR) to disclose the credit status of corporate bonds in the default prediction task. However, the textual data of credit rating reports (CRRs) contain richer and more comprehensive information and are neglected in related work. In this paper, we propose a novel framework that draws on the unstructured data in CRR to predict the default of corporate bonds. We extract the rating opinion sentences (categorized as positive and negative) from the collected CRR files and use latent Dirichlet allocation (LDA) models to mine topic information. The bilateral topic information of positive and negative opinions can reflect the anti-risk ability and potential risk of corporate bonds, respectively, based on which the constructed topic features are used for default prediction. Results on real-world Chinese corporate bonds dataset show that the bilateral topic information of CRR can significantly improve the predicting power of models (LR, SVM, KNN and MLP) under three performance metrics (AUC, KS and H-measure). By analyzing the ranking of topic features using SHAP value, the proposed framework can explain the factors that affect bond defaults, which can provide a basis for the decision-making of investment behavior.

Measuring Data Quality from Building Registers: A Case Study in Italy

Geographic data quality is a complex issue requiring continuous operational improvements. Considering this to be one of the most topical research and technical issues in official statistics and environmental monitoring, this study re-connects the operational dimension of ‘geographic data quality’ with the broader issue of monitoring the quality of official statistics. By estimating the accuracy of public (spatially explicit) data, this study illustrates an operational framework with an exploratory exercise in estimating the geographic data quality characteristic of a specific information source within the official statistical system (i.e., building registry) in a given European country, namely, Italy. The results of this exercise provide a paradigmatic example of profound innovation in the activities of statistical services in Europe and specifically the Italian National Statistical Institute (Istat), transitioning from independent (and poorly connected) field surveys to an integrated system of registries. Since several studies are based on spatially explicit survey units, it is essential to estimate the quality of geographical data, especially those derived from information sources where space is topical information, such as (local, regional, or national) building registers. Thanks to the results of an empirical exercise applied to Italian building registers, the present article will discuss the issue of data accuracy, considered the main issue related to monitoring geographic data quality, from an official statistics’ perspective. Statistical indicators will be proposed for the assessment of systematic and random errors of spatially explicit measures, possibly enabling a quali-quantitative improvement in the semantic content of building registers that address the inherent requirements of official statistics. Such indicators have some positive implications for the entire system of official statistics in Italy and, for generalization, within the European Statistical System.

Imaging Informatics Education in Clinical Informatics Programs: Perspective from Imaging and Clinical Informatics Professionals.

Imaging and Clinical Informatics are domains of biomedical informatics. Imaging Informatics topics are often not covered in depth in most Clinical Informatics fellowships. While dedicated Imaging Informatics fellowships exist, they may not have the same rigor as ACGME (Accreditation Council for Graduate Medical Education) accredited Clinical Informatics fellowships and they do not provide a direct path toward subspecialty board certification. We compared published curricula and test content between Clinical and Imaging Informatics fellowship programs. We then highlighted differences between training programs and identified overlapping topics and opportunities for additional education for each type of trainee. Published consensus curricula and topics were extracted for each specialty. Two informaticists compared topics as shared or not shared between specialties. Next, test content outlines were compared for each specialty exam, extracted, and classified as shared or not shared content. A Venn diagram was created to highlight areas unique to each specialty as well as areas of overlap. There were 139 Clinical Informatics topics compared with 97 Imaging Informatics topics. Of the 139 Clinical Informatics topics, 115 (83%) were covered in the Imaging Informatics curriculum. Of the 97 Imaging Informatics topics, 74 (76%) were covered in the Clinical Informatics curriculum. When using test content outline data, 170 out of 397 (43%) Imaging Informatics topics matched to 64 out of 139 (46%) Clinical Informatics topics. We describe examples of overlapping topics and those unique to each program to identify potential areas to expand. Imaging Informatics and Clinical Informatics fellowship programs have some overlap with areas unique to each. Our review may help guide those seeking informatics education and potential certification. As enterprise imaging evolves, these differences may become more important and create knowledge gaps, if not systematically evaluated.
