(IEEE, 2022-12-09) Sumeera, S; Pesala, N; Thilani, M; Gamage, A; Bandara, P
The fisheries industry is vital to the Sri Lankan economy because it provides a living for more than 2.5 million coastal communities and meets more than half of the country’s animal protein needs. Today, the fishery community in Sri Lanka is facing several grant problems. Among them, not getting a decent fish price for their harvesting, the inability to identify diseases in shrimp cages in the early stages, and the inability to identify fish species by observing their external appearance. This research developed a prototype mobile application “Malu Malu” to avoid the above-mentioned problems. It facilitates to the prediction of market fish prices, identifying shrimp diseases in their early stages, and identifying fish species by observing their external appearance. The proposed predictive models of the “Malu Malu” contains three main models developed using inseption V3 Convolutional Neural Network (CNN) model for image classification and Linear Regression is used for creating a model for predictions. The experimental results of these models showed above 85% of accuracy.

(IEEE, 2020-12-10) Gajanayake, R. G. U. S; Hiras, M. H. M; Gunathunga, P. I. N; Supun, E. G. J; Karunasenna, A; Bandara, P
Selecting the most suitable candidates for interviews is an important process for organizations that can affect their overall work performance. Typically, recruiters check Curriculum Vitae (CV), shortlist them and call candidates for interviews which have been the way of recruiting new employees for a long time. To minimize the time spent on the above process, pre-screening mechanisms are nowadays implemented by organizations. However, those mechanisms need sufficient information to evaluate the candidate. For example, in case of a software engineer, the recruiters are interested on the programming ability, academic performance as well as personality traits of potential candidates. In this research, a pre-screening solution is proposed to screen the applicants for the post of Software Engineer where candidates are screen based on an initial call transcript, GitHub profile, LinkedIn profile, CV, Academic transcript and, Recommendation letters. This approach extracts textual features of different dimensions based on Natural Language Processing to identify the Big Five personality traits, CV and GitHub insights, candidate's skills, background, and capabilities from Recommendation letters as well as programming skills and knowledge from Academic transcript and Linked Profile. The results obtained from the different areas are presented and shown that the selected supervised machine learning algorithms and techniques can be used to evaluate the best possible candidates.

(Springer, Cham, 2017-09-20) Halloluwa, T; Vyas, D; Usoof, H; Bandara, P; Brereton, M; Hewagamage, P
Financial literacy can play an important role in supporting the livelihood of the poor. Sri Lanka, being a country that aims to become a knowledge economy, has started to integrate the use of technology in its primary education. This paper presents a case study from a Co-Design activity with primary school children in rural Sri Lanka to ideate designing of mobile applications to engage primary school students in financial literacy. Three workshops were conducted spanning over two months based on the bonded design method. Techniques involving bags of stuff, storyboarding and stickies were utilised to support idea generation. Two themes; shopping and transporting were prominent among the final designs. From the findings of this paper, we discuss the design inspirations of the study and the impact that scaffolding practices had on the outcomes of the study. Finally, we lay out some initial guidelines to follow when conducting co-design workshops with rural and resource constrained children in Sri Lanka.

(IEEE, 2021-03-27) Karunasena, A; Bandara, P; Jayasuriya, J. A. T. P; Gallage, P. D; Jayasundara, J. M. S. D; Nuwanjaya, L. A. P. Y. P
Usage of smart learning concepts have increased rapidly recently as better teaching and learning methods. Smart learning concepts are especially useful for students to learn better in large classes. In large classes, the lecture method is the most popular method of teaching. In the lecture method, the lecturer presents the content mostly using lecture slides and the students make their own notes based on the content presented. However, some students may find difficulties with the above method due to various issues such as speed in delivery. The purpose of this research is to assist students in large classes in the following content. The research proposes a solution with four components namely note taker, slide matcher, reference finder, and question presenter which are helpful for the students to obtain a summarized version of the lecture note, easily navigate to the content and find resources, and revise content using questions.

Inclination of teachers towards incorporating mobile game based learning into primary education: A Sri Lankan case study
(MECS (http://www.mecs-press.org/), 2018-04-08) Bandara, P
Incorporating information and communication technology (ICT), especially computer/mobile games into teaching and learning has been identified as a proven method of increasing primary grade students’ intrinsic motivation towards learning. However, in countries like Sri Lanka with teacher centric education cultures, the teacher still plays a significant role in the child’s education process. Therefore, it is imperative to look at the teachers’ willingness and inclination to integrate technology enhanced games in their classrooms. The purpose of this study is to investigate the teachers’ preparedness, attitude towards integrating mobile games in teaching and the issues faced by the teachers when trying to use technology in the Sri Lankan primary classroom. A questionnaire for assessing mobile game based learning readiness was designed and used as the research instrument to assess the inclination of teachers to incorporate mobile-based games for learning in their classroom. The survey was conducted involving primary school teachers in four Type 3 schools of Gampaha district in Sri Lanka. Type 3 schools have classes only up to grade 8. It was identified that the teachers in Type 3 schools of Gampaha district are moderately inclined towards incorporating mobile games into their day-to-day teaching activities.

Machine Learning Technique based Trip Planning System - TripMa
(Institute of Electrical and Electronics Engineers, 2022-10-22) Vishwajith, L; Attanayake, H; Rangana, S; Ushara, T; Bandara, P; Rupasinghe, S
Travel planning is a tedious task to engage from the perspective of travelers since it involves crucial and critical decision-making due to a lack of foreign geography and cultural knowledge. Initially, the concept of traveling through travel agencies was used and it was slowly diminishing due to the fact of freedom and exploration are too constant and bounded according to the organizer's perspective. The proposed model overcomes almost all existing challenges and removes the traveler's local knowledge gap by using the dynamic prediction and recommendation features. The proposed system has identified the importance of grouping or the sharing expectation of a traveler through mapping out the best matching companions along with identification of tourist attractions and the best time to visit those places, which also included safety precaution methodologies to the travelers, which provide them the capabilities of preparing and mitigating the potential risks along with the traveling areas. The inclusion of the user feedback analysis model will impact identifying the user's perspective of the system and ensures users' trust towards the system, The system has iteratively used location-based knowledge through third-party APIs such as GOOGLE MAP API. The below sections will describe and illustrate the modes of machine learning techniques used, weighted models, and the NLP data mining methodologies used to acquire the systems architecture.

(Association for Computing Machinery, 2018-12-04) Halloluwa, T; Bandara, P; Usoof, H; Vyas, D
This paper presents findings from a set of co-design workshops aimed at identifying the core values of underbanked women from rural Sri Lanka, associated with their everyday financial practices and experiences. We sought to gain in-depth insights into the aspirations, rationales, and concerns of this demography, where traditionally household finances are handled by men. In collaboration with a Microfinance Institute (MFI), we carried out two co-design workshops involving 17 participants. We used group discussions and various design activities such as persona creation to enable participants to share their experiences related to household finances. From our findings, three central values associated with household finances came out strongly: Supporting Family, Independence, and Spiritual Beliefs. We conclude by reflecting on the values identified while providing suggestions to support those through technology
