Rethinking the Promotion Brought by Contrastive Learning to Semi-Supervised Node Classification

Graph Contrastive Learning (GCL) has proven highly effective in promoting the performance of Semi-Supervised Node Classification (SSNC). However, existing GCL methods are generally transferred from other fields like CV or NLP, whose underlying working mechanism remains underexplored. In this work, we first deeply probe the working mechanism of GCL in SSNC, and find that the promotion brought by GCL is severely unevenly distributed: the improvement mainly comes from subgraphs with less annotated information, which is fundamentally different from contrastive learning in other fields. However, existing GCL methods generally ignore this uneven distribution of annotated information and apply GCL evenly to the whole graph. To remedy this issue and further improve GCL in SSNC, we propose the Topology InFormation gain-Aware Graph Contrastive Learning (TIFA-GCL) framework that considers the annotated information distribution across graph in GCL. Extensive experiments on six benchmark graph datasets, including the enormous OGB-Products graph, show that TIFA-GCL can bring a larger improvement than existing GCL methods in both transductive and inductive settings. Further experiments demonstrate the generalizability and interpretability of TIFA-GCL.
Sistem Peramalan Waktu Masak Fisiologis Benih Padi Menggunakan Double Exponential Smoothing

The success of the rice harvest is influenced by various factors, one of which is the selection of quality seeds. Good rice seeds are those obtained during physiological maturity where the moisture content in the seeds is not too low/high. The physiological cooking time of rice seeds can be done by calculating heat accumulation and testing germination. Heat accumulation is the total heat energy from solar radiation received by rice plants, this value can be calculated by recording the maximum, minimum, and humidity temperature data continuously for 90-120 days. Meanwhile, post-harvest laboratory tests were carried out for germination. Temperature and humidity data that were stored and processed quickly of course could be predicted the physiological ripening time of seeds better. Therefore in this article, a web-based forecasting system with the double exponential smoothing method was developed and supported by a graphical display of the data development. This research was conducted on 3 rice varieties namely IR64, Sinta Nur, and Ciherang. The yield that could be conveyed for the IR64 variety reached 85% germination with heat accumulation of 1147 and 105 DAS. The Sinta Nur variety had 92% germination and 86% Ciherang variety with heat accumulation of 1266 at 115 DAS. In this forecasting process, the MAPE value is 0.205 with alpha 0.9 and beta 0.1.

Frugal Decentralized Learning

Machine learning is currently shifting from a centralized paradigm to decentralized ones where machine learning models are trained collaboratively. In fully decentralized learning algorithms, data remains where it was produced, models are trained locally and only model parameters are exchanged among participating entities along an arbitrary network topology and aggregated over time until convergence. Not only this limits the cost of exchanging data but also exploits the growing capabilities of users' devices while mitigating privacy and confidentiality concerns. Such systems are significantly challenged by a potential high-level of heterogeneity both at the system level as participants may have differing capabilities of (e.g., computing power, memory and network connectivity) as well as data heterogeneity (a.k.a non-IIDness). The adoption of fully decentralized learning systems requires designing frugal systems that limit communication, energy and yet ensure convergences. Several avenues are promising from adapting the network topologies to compensate for data heterogeneity to exploiting the high levels of redundancy, both in data and computations, of ML algorithms to limit data and model sharing in such systems.

Reforms and Challenges in Teacher Education

In ancient times, the teachings of the monastery were taught by teachers rather than the training of teachers.Teacher training is more meaningful than the old word.Academic work is about acquiring skills.It requires a lot of preparation to be effective and dexterous.There are two types of programs in teacher education: pre-service education and in-service education.Pre-service education is provided to those who want to join the education profession.And that includes theoretical education and practical education.So that future teachers can be taught the essential skills of their profession and they can perform their functions effectively.General Chat Chat Lounge Teaching work is a very high skill-oriented operation, so no one can do it satisfactorily without solid training.No nation can depend on its quality, people.The quality of the people depends on their education and the education base is on the quality teachers, and these good teachers depend on the education they receive.Achievement of the desired goals of education requires a great deal of teacher training.Teachers should be constantly aware of the changes in the practice of education and they should be fully prepared to take advantage of this change so that they can integrate education with people's needs, lives and aspirations; And thus the social, essential for the fulfillment of our national goals.
Readibility, Meaning, and Function of Foreign Language on Billboards in Surakarta: A Critical Discourse Analysis

This research aims to describe the use of foreign languages on billboards in Surakarta. This research was a single case study obtained from the objective data of billboards along Slamet Riyadi Street Surakarta. The data sources were from the commercial billboards considering several criteria that have been determined in which the billboards should not be owned by either district government or individual, for campaign purposes, made in 2018, and so on. Those billboards are billboard from Gofood, McDonald's, and Samsung Galaxy Note9. Subsequently, effective data were obtained through observation and interview from informants in readability process. Manifestation of billboard as a form of discourse generates meaning based on critical discourse analysis approach. In addition to the function of billboard as marketing aspect of the company, it also functions to deliver important information, knowledge, and educative information for the readers. This research results show that the readability, meaning, and function of foreign languages assumption on advertisement of billboard are different from the marketing concept. Nonetheless, an emergence of foreign languages provides space for the readers to learn the vocabulary in facing globalization era. Moreover, it also reminds us not to forget the existing culture in Surakarta.

Minimal specification

In this chapter I will address the following issues: Redundancy and default: are predictable (i.e. redundant) elements underspecified, and what about elements that are contrastive? In other words, is there a role for (contrastive and radical) underspecification in RcvP? Markedness: how does RcvP express markedness? What is ‘markedness’ in RcvP? Minimal specification: given that underspecification plays a role in RcvP, how are minimal (i.e. maximally underspecified) representations determined? Phonological activity: can redundant or default properties be phonologically active? Constraints: which types of constraints can be formulated to restrict the set of possible segments to precisely those that occur in a given language?
