The MSc in DS and AI at USJ was designed in partnership with the Erasmus+ DS and AI consortium, a group of 15 European and Asian organizations with the mission of bringing European-standard advanced education to Asia. The aim of the MSc is to provide advanced courses and guidance in developing research skills necessary to develop innovative new data-driven technologies.

Data Visualization is often deemed to be linked with coding skills, intimidating any aspiring Data Analyst who’s just starting out. But is it really the case? (OR were we seriously misinformed on our odds of stepping into a data-driven career?). Tableau is one of the fastest growing Business Intelligence and Data Visualization tools that is easier to learn, faster to execute and gives far more intuitive and explanatory visuals to the onlookers. And predominantly due to this user-friendliness while giving the ability to create classy visuals, many organizations have shifted to using Tableau or PowerBI as their primary Data Analysis software from previously code-dominant software. Hence the dire need to hone our Data Visualization skills via booming software like these is constantly pressed upon by the corporate domain. Contrary to popular belief, mastering a certain skill doesn’t always have to be hard or take years. This is precisely the point that we proved by the Introduction to Tableau session we had on 23rd Friday, July 2021 from 5.00pm onwards.
The session was conducted by Mr.Janith Wanniarachchi, President of the Statistics Society of University of Sri Jayewardenepura, Trainee Data Analyst at Trabeya. He has several years of experience in visualizing and obtaining feedback on his visualizations through the R for Data Science Community. In this session, the main focus was to help the participants get an overall idea of the functionalities available within Tableau through hands-on demonstrations. In the first half of the webinar, the newly released Tableau Viz (Beta) was demonstrated. The Tableau Viz (Beta) allowed Tableau users to create visualizations through their web browser without needing to install the Tableau Public software. The CO2 emissions of different countries were used to demonstrate the basic functionalities of connecting data, creating worksheets and arranging sheets in dashboards to be shared eventually. This demonstration slightly graced the fundamental functionalities as the Tableau Viz feature was still in Beta level of testing.
The next demonstration started by using the dataset on the profitability of Hollywood movies. The dataset contained a small number of rows but the columns were rich in information. However this demonstration carried some twists and spontaneity, the demonstrations were done with the suggestions from the audience and moreover, through them different functionalities of Tableau were also explored such as calculated fields, grouping, dual axis etc. along with the mechanisms of sharing Tableau dashboards.
As we reach the end of the visualization workshop series leading into Pearl Viz ‘21 (the Data Visualization competition organized by the Statistics Society of University of Sri Jayewardenepura), our heartiest gratitude goes to Dr. Rajitha Silva, Senior Treasurer of the Statistics Society of University of Sri Jayewardenepura for motivating and guiding us to focus on having this session, Mr. Janith Wanniarachchi for dedicating his time and energy to sharing the knowledge he acquired with anyone and everyone who were interested, the Pearl Viz Team for organizing this event, along with the Statistics Society Top Board and Committee for being a massive strength behind this webinar. If you are currently an undergraduate of Faculty of Applied Science of University of Sri Jayewardenepura, we would highly recommend that you take part in Pearl Viz, a data visualization competition where you can use data to tell the story that you see using tools that we have taught in these webinars. As parting words, we will leave you this message to remind you that while webinars are a good way to get a head start, self learning can go a long way and sharing what you learn with the community can be immensely helpful.

Have you ever felt anxious trying to find a “final-final-edited-version4” file in a sea of “final”s and “version”s? Or maybe you were asked by your supervisor to go back and work on a previous version of your project file. The answer is most likely a “yes”. We often face dilemmas trying to understand the edits that you or your teammates have done to certain files throughout the project timeline and why particular decisions were taken midway to change the game plan. This often pauses the ongoing actions of the team since now they have to go back to square one and work their way up while manually recording every review and change. Hence tracking the versions of files in a directory is a much needed facility especially for data evangelists of today. This is why we, the Statistics Society of the University of Sri Jayewardenepura decided to take the plunge to start making our aspiring Statisticians’ lives easier by introducing to them the world of Git.
Git fundamentals session was held on the 18th of July, 04:00 PM onwards via Zoom with over 100 participants arriving to learn about Git and how to start using it for their own projects. The speaker of the session was Mr. Adithya Narasinghe (Deep Learning Engineer at labml.ai, Consultant Software Engineer at oDoc) who took an unconventional approach in making the session fun and engaging to all its participants. The session started off by him explaining why git is necessary, with the reason being that tracking the version of your documents and files is essential to reduce unnecessary clutter and to understand the changes made to the versions of your document. Then a fun, interactive kahoot session organized by him tested the knowledge of the audience based on what he had discussed, where most of the participants gave correct answers and scored points. He pointed how everyone has at some point used version controlling systems such as Google Docs or Google Slides etc. even without explicitly knowing what they were. And finally he ended his insightful workshop with a hands-on session on setting up git and connecting to github to perform a variety of tasks from committing changes to making pull requests on github.
We thank Mr. Adithya Narasinghe from the bottom of our hearts for accepting our invitation and choosing to educate an aspiring audience and inspire them to discover new approaches to upgrade their workflows. Our gratitude also extends to the Senior Treasurer of the society, Dr. Rajitha Silva for consistently inspiring and encouraging us to take risks and be daring in the journey of distributing this much needed knowledge. Moreover, we thankfully acknowledge the immense support given by Mr. Janith Wanniarachchi,, the President of the Statistics Society who not only moderated the session by creating an interactive space between the speaker and the audience but guided us through the entire process to ensure a seamless execution of the project. This project would not have acquired this level of success if it weren’t for the dynamic team that includes Mr. Rajitha Lakshan, Ms. Rashmi Jayasekara and Ms. Chalani Pradeepika, who committed diligently behind the scenes to ensure the triumph that we have achieved. We are indebted to all their support and commitment throughout the project and beyond.
And finally, we thank all fellow data enthusiasts who participated in this insightful session and who keep motivating us to do what we do!
