Non-asymptotic analysis of Stochastic approximation algorithms for streaming data

We introduce a streaming framework for analyzing stochastic approximation/optimization problems. This streaming framework is analogous to solving optimization problems using time-varying mini-batches that arrive sequentially. We provide non-asymptotic convergence rates of various gradientbased algorithms; this includes the famous Stochastic Gradient (SG) descent (a.k.a. Robbins-Monro algorithm), mini-batch SG and time-varying mini-batch SG algorithms, as well as their iterated averages (a.k.a. Polyak-Ruppert averaging). We show (i) how to accelerate convergence by choosing the learning rate according to the time-varying mini-batches, (ii) that Polyak-Ruppert averaging achieves optimal convergence in terms of attaining the Cramer-Rao lower bound, and (iii) how time-varying mini-batches together with Polyak-Ruppert averaging can provide variance reduction and accelerate convergence simultaneously, which is advantageous for many learning problems, such as online, sequential, and large-scale learning. We further demonstrate these favorable effects for various time-varying minibatches.
The Use of Blockchain Technology in The Islamic Financial Industry During The Covid-19 Pandemic: Maslahah Perspective

Spread of the Covid-19 pandemic has swept across Malaysia causing severe disruption and malfunction of the economic sector.Trade agreements between two or more parties usually carried out in a face-to-face manner is not permitted during the Movement Control Order (MCO).However, blockchain technology has the capability to help coordinate and seal agreements safely without the need for face-to-face meetings.Trade agreements can use the Ethereum smart contract, which is aided by blockchain technology.This qualitative study, which applied the content analysis method, aimed to identify the importance of blockchain technology to the financial industry throughout the Covid-19 pandemic.Findings show that blockchain plays a significant role in the Islamic financial sector because it can be applied effectively during the pandemic; in addition to the benefits accrued in the form of the preservation of life and property.Each transaction is permanently recorded in the blockchain and it is difficult to delete or destroy it.It is also significant because it can be widely used for managing agreements between parties and implementing paperless transactions in the future.
ENGLISH LECTURERS' PERCEPTION TOWARD PROFESSIONAL DEVELOPMENT PROGRAMS

This study aims to explore the experiences and perceptions of lecturers on the professional development activities of lecturers in the English Language Education Study Program. This study applied a quantitative descriptive approach by using a questionnaire as an instrument to collect data. This study's subjects were the lecturers of the English Education Study Program at a private university in Jakarta. The findings indicate that the professional development activities that have been attended by the majority of English Education lecturers are research activities, both individually and in groups, conferences or seminars, and workshops or training related to courses and/or other topics related to education. The professional development activities needed by lecturers include training related to National Education Standards (60%), multicultural teaching (60%), knowledge and understanding (competence) of the subject (53%), and teaching for students with special needs ( 53%). This study also confirms that effective time management for organizing or developing professional development activities regarding teaching schedules and other administrative activities is urgently needed. That way, lecturers can still fulfill their obligations to teach, research, and do community service while still having the opportunity to develop their professionalism.
Sharp Analysis of Random Fourier Features in Classification

We study the theoretical properties of random Fourier features classification with Lipschitz continuous loss functions such as support vector machine and logistic regression. Utilizing the regularity condition, we show for the first time that random Fourier features classification can achieve O(1/n^0.5) learning rate with only O(n^0.5) features, as opposed to O(n) features suggested by previous results. Our study covers the standard feature sampling method for which we reduce the number of features required, as well as a problem-dependent sampling method which further reduces the number of features while still keeping the optimal generalization property. Moreover, we prove that the random Fourier features classification can obtain a fast O(1/n) learning rate for both sampling schemes under Massart's low noise assumption. Our results demonstrate the potential effectiveness of random Fourier features approximation in reducing the computational complexity (roughly from O(n^3) in time and O(n^2) in space to O(n^2) and O(n^1.5) respectively) without having to trade-off the statistical prediction accuracy. In addition, the achieved trade-off in our analysis is at least the same as the optimal results in the literature under the worst case scenario and significantly improves the optimal results under benign regularity conditions.
Variational Autoencoders for Opponent Modeling in Multi-Agent Systems

Multi-agent systems exhibit complex behaviors that emanate from the interactions of multiple agents in a shared environment. In this work, we are interested in controlling one agent in a multi-agent system and successfully learn to interact with the other agents that have fixed policies. Modeling the behavior of other agents (opponents) is essential in understanding the interactions of the agents in the system. By taking advantage of recent advances in unsupervised learning, we propose modeling opponents using variational autoencoders. Additionally, many existing methods in the literature assume that the opponent models have access to opponent's observations and actions during both training and execution. To eliminate this assumption, we propose a modification that attempts to identify the underlying opponent model using only local information of our agent, such as its observations, actions, and rewards. The experiments indicate that our opponent modeling methods achieve equal or greater episodic returns in reinforcement learning tasks against another modeling method.
SERVICE QUALITY FOR SUSTAINABLE USER SATISFACTION BY ACADEMIC LIBRARIES

The central focus of academic libraries in institutions of higher learning is provision of required information resources and services to members of the institution’s community. Utilization of academic library is measured by the amount of library information resources and services that are used in teaching, learning, pleasure, relaxation and research activities. Hussaini, Vashistha & Jimah (2018) stated that university library faces a critical challenge in responding to the new demand of the 21st century with growing demographic growth linked with a lack of appropriate usage of library resources. To ensure users satisfaction and optimum utilization of the libraries, adherence to provision of service quality is the sure answer. Service quality has been identified as an important factor which should contribute to an organization’s ability to retain loyal customers and thus contribute to improved organisational performance. The paper is an expository one to sensitize the academic librarians to the need to for quality service delivery to its users who unlike in the past, now have many information providers to choose from.

Therefore, it can be concluded that students' perceptions of Ms. PowerPoint were good and exciting. Also, the students felt learning English by using Ms. PowerPoint provided more help, especially in the context of raising activeness, motivation, and English competence in EFL classroom.
The Genesis of the Philosophical Tradition in Education

The article reveals the genesis of the philosophical tradition in education. The emphasis was placed on the study of the Plato’s work. In “The Republic” Plato wrote, “…when you meet encomiasts of Homer who tell us that this poet has been the educator (πεπαίδευκεν) of Hellas, and that for the conduct and refinement of human life he is worthy of our study and devotion, and that we should order our entire lives by the guidance of this poet we must love and salute them” (Plato, Republic 10.606e). The author took Plato’s instructions literally, emphasizing the importance of Plato in the creation of the philosophical tradition.
The increase in absolute theta power and the inhibition of light stimulus in cybersickness

Cybersickness results from the visual vestibule conflict, that is, the incoherence between the sensations related to real movement, in the virtual environment, and the visual stimuli. In response to the virtual environment, one can observe discomforts such as nausea, difficulty in concentrating, and headaches, among others. There are no studies in the literature that analyze the inhibition control of light stimuli in individuals sensitive to Cybersickness. Therefore, this study looked at the control of light stimulus inhibition in Cybersickness. The Sickness Susceptibility Questionnaire was used to divide the subjects into experimental and control groups, and quantify the signs and symptoms, comparing them before and after 3D virtual immersion and. Participants in both groups were examined with EEGq for absolute theta band power in the dorsolateral prefrontal cortex and ventrolateral prefrontal cortex during the light stimulus inhibition task before and after participants watched the 3D video. The partial results showed that there was an increase in the absolute theta band power in both groups comparing the moments before and after, as well as a significant difference in the experimental group compared to the control, for the same moment. Thus, it was observed that individuals who were exposed to 3D virtual reality and developed Cybersikness, showed greater absolute theta band power in the areas studied.
Illuminating Systemic Functional Grammatics (Theory) as a Viable Tool of Digital Humanities

The focus of the study is the application of Systemic Functional Grammatics (SFG) to text as a facility of meaning-making. Having provided a wide room for technological devices to read and account for elements of a text, it portrays the exercise within the scope of Digital Humanities (DH). The theory, championed by Halliday, describes a text from its systemic configurations to chain structures and social relationship frameworks. To explain the weight of SFG as an interface between text and technology, the author chose a poem, ‘Area Boy’, in which three perspectives of the mood system, thematic system, and transitivity system are instrumental to expose its nuances. The approach was followed by correlating the three systems together as a comparative analysis. The study reveals that ‘Area Boy’ operates in declarative clauses with heavy utilization of Subject and Finite. These are organized in marked themes. The contents of the text are represented in material processes (e.g. spent) with supports from both mental (e.g. remember) and verbal (e.g. said) processes. Some of the processes along with circumstances (e.g. Of washing …, Now that …) recur as repetitions for emphatic and enhancement purposes. On the one hand, the article concludes that SFG can assist in interpreting textual elements to generate meaning potential. On the other hand, through the SFG’s metafunctional applications to ‘Area Boy’, one can suggest that the society should give a helping hand to the less privileged. Such a behavior can eradicate vices experienced through the ‘Area Boys’ from the society.
An Inductive-ROC Based Model for Determining Purchasing System Requirements

The success of system development studies depends on the completeness and accuracy of the requirements collected from system user and stakeholders.Mistakes and deficiencies in the requirements determination process lie in the failure of many system development studies.The dynamism and complexity of today's systems make the requirements determination process even more complicated, and the requirement determination phase, which is the primary stage of system development studies, gains excellent importance.Although there are many techniques, strategies, and models in the literature to improve the requirements Determination process, there are very few studies on their multiple-use, classification of needs, and their experimental realization in a real system.In this study, a system development study was carried out using the System Requirements Model (SRM), which has a flexible structure that allows the system needs to be determined with the use of multiple techniques, at the same time classifies the identified requirements, can decide on the determination levels, and allows the work to be stopped if a sufficient level of needs is determined The developed model consists of three stages: requirement identification, rulemaking/technical/needs matrix creation and classification of needs.In the needs determination process, collection, presentation, verification, and sort of needs.In the second stage of the model, an analogy was made, and the needs and techniques were grouped with the ROC algorithm, and the rule-based RULES-3 algorithm was used to universalize the model.In the third stage of the model, needs were determined based on technical/technical combinations.
