DASH: Distributed Adaptive Sequencing Heuristic for Submodular Maximization [article]

Tonmoy Dey, Yixin Chen, Alan Kuhnle
2022 arXiv   pre-print
MapReduce (MR) model algorithms for maximizing monotone, submodular functions subject to a cardinality constraint (SMCC) are currently restricted to the use of the linear-adaptive (non-parallelizable) algorithm GREEDY. Low-adaptive algorithms do not satisfy the requirements of these distributed MR frameworks, thereby limiting their performance. We study the SMCC problem in a distributed setting and propose the first MR algorithms with sublinear adaptive complexity. Our algorithms, R-DASH,

Additionally, we provide a memory-efficient framework MED that eliminates the memory limitations of all MR model algorithms resulting from large distributed setups or considerable cardinality constraints. Finally, we provide empirical evidence to demonstrate that our sublinear-adaptive distributed algorithms provide orders of magnitude faster speedup in runtime compared to current state-of-the-art distributed algorithms while producing near identical results.

Addressing Voluntary Turnover in Manufacturing Sectors: An Empirical Study

Md Habibur Rahman, Md. Al-Amin, Muhammad Abdus Salam, Trisha Saha, Tonmoy Dey
2021 Zenodo  
Main objectives: Voluntary turnover of employees are increasingly becoming serious problems in manufacturing sectors. Turnover creates a hindrance to practical access to ensure a continuous production process. That is why, turnover prediction model was proposed to address such problem in manufacturing organizations. Background problems: Despite the introduction of automation in manufacturing-based organizations across the world, Human resources are still one of the key determinants of
more » ... and Voluntary employee turnover still remain the barrier to remove such problem. Novelty: The study took broad aspects resulting in voluntary turnover firstly and applied the multinomial regression and multilayer perceptron model for analyzing categorical data. Research method: Along with the descriptive analysis, the research applied multinomial regression and multilayer perceptron model to analyze data. Besides, Secondary data of manufacturing-based organization was collected from kaggle.com archive for the study purpose. Findings: Table 2 to 8 display the empirical findings of the study. Table 5 explained correlation and table 6 showed regression results of the study. Correlations showed that performance score and complaints directly contribute to the turnover decision, while multinomial regression proved that error, performance score, pay, complaints, abutments lead to the voluntary turnover decision. Contribution: The findings contribute to the literature by identifying different causes of voluntary turnover in manufacturing organizations. The study will help the manufacturing organizations to address the voluntary turnover. Conclusions: The different independent variables (the reason for termination, performance score, pay, error, and _90_days, etc.) are identified to suggest the possible action to be taken by the organization to minimize the influence of voluntary turnover. Manufacturing organizati [...]

Relationship between Organizational Strategy and Leadership Style in Performance Efficiency

Md. Habibur Rahman, Noakhali Science and Technology University, Tonmoy Dey, Md. Al-Amin
2019 Asian Business Review  
The strategy of an organization reflects the probable ways to achieve the objectives of the organization. Successful organization is the result of effective implementation of organizational strategy and leadership. The study has examined the relationship between organizational strategy and leadership to achieve performance effectiveness and objectives of the organization. In this paper, extensive studies are conducted on different peer reviewed journals which is based on leadership and

ADOPTION OF INFORMATION & COMMUNICATION TECHNOLOGY AMONG THE STUDENTS AT TERTIARY LEVEL: BANGLADESH PERSPECTIVES

Muhammad Abdus Salam, Trisha Saha, Tonmoy Dey
2020 EPRA International Journal of Economic and Business Review  
Information and Communication Technology (ICT) is extensively being used for educational purpose because it helps to make both learning and teaching effective and meaningful. Again, it shrinks the obstacles of habitual learning systems like allowing students to access unlimited educational resources and providing required data timely. Bangladesh has made marvelous betterment in this sector in the last couple of years especially in tertiary level. Now, it is high time to justify how the tertiary

The study was conducted at the Noakhali Science and Technology University (NSTU) with randomly collected data from 250 students of various departments. It has justified the perceptions, behavior and expectations of tertiary level students towards the adoption of ICT. The results of this study are expected to be useful to the educational policymakers, institutions, educators and the relevant parties. KEYWORDS: ICT Adoption, ICT in Education, Tertiary Education, NSTU, Bangladesh.

Optimizing Asynchronous Multi-Level Checkpoint/Restart Configurations with Machine Learning

Tonmoy Dey, Kento Sato, Bogdan Nicolae, Jian Guo, Jens Domke, Weikuan Yu, Franck Cappello, Kathryn Mohror
2020 2020 IEEE International Parallel and Distributed Processing Symposium Workshops (IPDPSW)  
With the emergence of versatile storage systems, multi-level checkpointing (MLC) has become a common approach to gain efficiency. However, multi-level checkpoint/restart can cause enormous I/O traffic on HPC systems. To use multilevel checkpointing efficiently, it is important to optimize checkpoint/restart configurations. Current approaches, namely modeling and simulation, are either inaccurate or slow in determining the optimal configuration for a large scale system. In this paper, we show

Analyzing the Extents of the Factors Influential to the Level of Job Satisfaction: A Study on Bankers from Dhaka City's Private Commercial Banks

Tonmoy Dey, Shohel Md. Nafi, Masum Miah, Mohammad Maruf Uddin
2019 Zenodo  
Job satisfaction depends on employees' perception and attitude towards their job and the environment where their job belongs to. It is critical to the overall performance and profitability of the organization as there is a strong correlation between job satisfaction and employee motivation as well as productivity. The more satisfied an employee is the more productivity an organization can expect from him. This study is associated with some critical factors upon which job satisfaction mostly

The study has five dependent variables- working environment, supervision, pay and promotion, performance evaluation and relationship with coworkers. Job satisfaction is considered as the dependent variable. This study is empirical in nature and the overall research is based on both quantitative and qualitative statistical methods such as- Mean, Standard Deviation, Weighted Mean, and Pearson Correlation Analysis. Five hypotheses are tested to achieve overall objectives of the study using ANOVA. 200 employees from 39 private commercial banks within Dhaka city are used as the sample population for the study. After the analysis some recommendations are made for the stakeholders based on the findings with a view to providing some insights regarding job satisfaction and the factors influential to it. The insights of the study can practically be applied to Human Resource (HR) policy and decision making regarding effective HR management.
