These Seidenberg graduate students are serving tennis with a new global ranking system

Three former graduate students and current alumni from Pace University’s Seidenberg School of Computer Science and Information Systems intrigued Floridian officials with a paper they wrote and presented in Miami in July 2018.

The alumni in the Software Development and Engineering program, Dionysios Kakaroubas, Jesseka Farago, and Stephen Webber, wrote a research paper on the topic of tennis scoring and ranking. Dionysios started the project because of his fascination with the sport.

“I’ve been a tennis fan since I was a little kid, so I know how the system works right now and how the current ranking system is. I know that many fans and players complain about it, so I knew that there were flaws with it. I wanted to develop a new formula so I could make a new version of it to eliminate these flaws,” Dionysios explains. “If you have more losses, [with our system] you cannot be higher up in the rankings. This is happening right now and all of the fans are complaining about it.”

The team developed a new system to improve the way tennis rankings are generated. Instead of using one attribute to determine only rank and scoring, they tested their theory that using the following three attributes would make a better system: abstention, number of tournaments played, and “bonus points for multiple wins in high-level tournaments.”

“We also developed a scenario generator,” Dionysios says. “It is a piece of software that predicts the different outcomes of different rounds of a tournament.”

They presented their software and a paper titled, The Enhancement of the Tennis Ranking System: A Software Solution, in July 2018 at the International Conference of Sports and Society in Miami.

The presentation gained the attention of Mathew Ratner, Associate Director of Sports Tourism at the Greater Miami Convention and Visitors Bureau. Kakaroubas is currently communicating with Ratner about how to integrate the Pace group’s new ideas into Florida’s tennis ranking system.

After presenting their paper in Miami, the group decided to reach out to a conference in Kyoto, Japan. They were accepted to attend and present at the conference in November of 2018!

In Kyoto, the team presented the latest draft of their research paper titled, An Elaborated Software Solution: The Tennis Ranking System, at the 20th International Conference on Sport Science and Social Science in Sport.

 

“The Kyoto experience was one of a kind. We had the opportunity to meet people who are involved in organizing the Olympics’ tennis Championships for Tokyo 2020,” Dionysios exclaims. “We also discussed Japan having its own national tennis league with a separate ranking system than the World Tour one. That was great feedback for us and our publication. There is a recognition that our work could potentially have a worldwide impact and can be placed in any country, culture, and part of the world.”

The latest version of the paper adds in two more attributes for scoring and ranking: consecutive wins and consecutive losses. The team also accounts for the surface that the game is played on with three different options: clay, grass, or a hard surface. With a total of five attributes contributing to the final score and taking the playing surface into account, the team’s system is stronger than the existing tennis ranking system.

As for the future, Dionysios says that he and the rest of the team are “planning to develop this project. Not just in the paper, but to bring it to real life in a real-life project.”

The team is still in touch with contacts from both Florida and Japan. According to Dionysios, they’re looking to start a new state league within the next year in Miami.

“I am really satisfied and happy with what we have achieved so far. Our paper got and [is] still getting a lot of attention and a promising future seems to be ahead! My idea, our work ethic and efforts seem to pay off!”

As they continue to develop the software, the team will work to make the tennis ranking system better for current and future players. Keep your eyes on their names, because they’re serving the sport with a game-changing product.

Seidenberg Student Receives an Award at Eastern Colleges Science Conference

Seventeen students from the Seidenberg School of Computer Science and Information Systems traveled to the Eastern Colleges Science Conference on April 6th. It was a wonderful chance for students to experience from start to finish, the process of preparing for and presenting at an esteemed conference. The experience was made possible by the Kenan Student-Faculty Conference Grant.

Out of the 17 capstone students and graduating seniors whose research was accepted, 12 students presented posters and 5 gave platform presentations (15-minute oral presentations with a question and answer session afterward). While the presentations were the highlight of the conference, all the students were able to network and learn from students of surrounding institutions.

Seidenberg Computer Science Professor, Pauline Mosley, explained that this experience was intended to prepare students for future conferences. The students who attended learned “how to interact, network, and make collaborations.”

Pauline also mentioned the importance of conference participation: “the art of presenting one’s research provides student[s] with another dimension of learning that [can] only be achieved by conference participation.”

While all the students gained exposure that will benefit their careers and education, Pauline wanted to note one presenter who stood out from the rest: Quincy Doccy.

 Quincy, a graduate who received his BS in Computer Science this past May, presented his platform presentation “See Through Your Meal” at the conference. He competed against Ithaca College students and won in the category of Psychology and Health. Quincy received the Award for Best Platform Presentation.

Pauline explained just why Quincy’s presentation was award-worthy: “Some students read off the PowerPoint slides, but Quincy – walked around the room, told jokes, gave history, and discussed his project calmly and it was great!  His project entailed analyzing the data for restaurant reviews and his reason for doing this project was that he got food poison[ing] after eating at one of the restaurants.”

“My presentation, ‘See Through Your Meal’ was on the NYC restaurants letter grade system,” he explained. “The objective of the project was to analyze the NYC Department of Health and Mental Hygiene (DOHMH) health inspections results datasets to identify the deficiencies and limitations of the current restaurant letter grading system and determine its effectiveness. I also implemented an application prototype that’d help restaurant goers to make informed decisions when choosing to dine at their next restaurant.”

Quincy noted that this presentation was the final step in completing his capstone course. He believes this step in his education was crucial, and he enjoyed the conference.

“It was an awesome experience to listen to other college students present their research from diverse fields and receive positive feedback on my presentation,” Quincy explained. “I also enjoyed networking with faculty members and other students.”

When asked how it felt to win an award for something he worked so hard on, Quincy explained that “it was great to know that all the hard work and effort I put into my research was acknowledged and recognized by the judges.”

Quincy did an excellent job of representing Seidenberg and the Pace University community. We’re proud of all that he and the other students accomplished at this conference.

Seidenberg student wins Airbnb Pricing Challenge on Westchester campus

Ian Carvalho, a Seidenberg student in the process of obtaining an MS in Computer Science, is a student to watch. The award-winning individual spends his time volunteering and creating apps dedicated to assisting others when he has a free moment. His most recent success came from the Pace AirBnB Pricing Challenge where he won first place!

As an undergraduate student, Ian was fortunate enough to be the recipient of the Brazilian government-funded scholarship, Science Without Borders, which helped him study in the United States for a year. The scholarship led him to Pace University to pursue undergraduate and graduate degrees. After obtaining his Bachelor’s degree in Computer Science in 2016, Ian scored a Research Internship with IBM over the summer. When fall rolled around, he decided to stick around at Seidenberg for his graduate education, choosing to pursue a Masters in Computer Science.

So far, Ian has called his time at Seidenberg, “very intense.” As a Graduate student, Graduate Assistant for Dr. Juan Shan, and PIP Design Factory team member, it’s safe to say that his time has been exactly that—but he’s not done yet.

During his time as a Seidenberg student, he’s gone above and beyond in his extracurricular activities. Ian taught a workshop on iOS development in partnership with PCS, won first place in the App Design Contest with the Entrepreneurship Lab for his application Helpteer, and participated at a Humanitarian Hackathon hosted by Google to assist the non-profit, Techo, which seeks to overcome poverty in slums.

Most recently, Ian identifies himself as a volunteer, Agile NYC participant, and a Java tutor. Beyond those activities, he’s a freelance iOS and Game Developer and Senior Software Developer at BRQ Digital Solutions. Plus, he is working on his master’s thesis.

“Currently, I am writing my thesis on applying deep learning to assist medical imaging problems [such] as Breast Cancer detecting and Knee bone segmentation,” he explains.

All of Ian’s successes are considered a win for all of the Seidenberg community, but his first place win for the Pace AirBnB Pricing Challenge is definitely something to recognize.

The challenge was created by Professor Lala and sponsored by INFORMS on the Westchester campus. The goal of the competition, which was held through the platform Kaggle, was to create a machine learning program with the capability to predict the current price of a listing using the given Airbnb data. Students were encouraged to actively participate in order to make their entry the best possible.

“I participated very actively during the last week of the challenge,” Ian explains.

Ian developed an artificial intelligence model to predict rental pricings for Airbnb listings, and his role of actively participating during the last week led to his ultimate victory. But his triumph did not come easily. Ian detailed the process of testing different models to see which achieved the highest performance. In the end, he combined the results of several models to predict the closest result.

“The challenge consisted in analyzing a dataset with more than [just] variables as a number of beds, reviews, amenities, etc. from [an] Airbnb listing. Part of the dataset ([which was] used for training) had the pricing, which the model used to learn patterns,” he explains.

These analyses were not a one and done deal. Ian explains that he had to rework the model many times.

“After learning, the model would try to predict the prices in the testing dataset,” he explains. “Results would then be submitted to Kaggle, that would compare to the real results and assign a score. It sounds simple, in theory, but the work involved many steps and especially because I was working solo, it got very intense at first I would have to clean the data, remove useless columns, fill missing values and encode some of the data in a way that’s understandable to the model.”

The process was long, especially since Ian spent most of the last week of the challenge really cramming to achieve the best result. When he received that win in the end, all of his hard work and maximum effort worth it. When asked about how he felt about winning, Ian summed it up with one word: “amazing.”

“I knew I had a good result because of the way that the competition works. They show a public partial leaderboard and when the competition finishes they disclose the complete result,” Ian explained. “So it could be possible that someone at the first place in the public leaderboard would be placed in second in the final score. So until the last minute, I was trying to improve my model to make sure I would win.”

As for his overall experience, Ian would recommend it to anyone.

“It’s very rewarding. When I first started, I wasn’t expecting to win, as this was my first challenge of the kind, but I got good results and they kept improving with every submission. I learned a lot and it was very fun,” he notes.

Seidenberg students have numerous opportunities throughout the school year to compete in tech challenges, Hackathons, and much more! Make sure you check in with our social media to see what challenges are coming up next.

Learning to love through astrology and putting color back into the world: software engineering class presents final application projects

While finals can be a stressful time for students each time they come around, they can also be the perfect time to work with classmates on projects they feel passionate about. The season for cramming and test taking can also be an opportunity for collaborative innovation. When the Software Engineering (CS389) class presented their final projects in the Seidenberg Lounge on May 15th, it seemed as though that innovative energy was thriving.

The leading professor for the class, Dr. Shahed Mustafa, reviewed the team projects with assistance from Professor Avery Leider and Dr. Christelle Scharff. The eight groups of undergraduate students presented software applications they created to tackle real-world problems and generate an environment of positivity.

The students worked with Android Studio, Photoshop, Firebase, GitHub, and numerous other applications to bring their ideas to life. The teams created apps in a Scrum framework starting from an idea. Their ideas ranged from a game featuring adorable bartending kittens to a chat room app that helps groups of friends and coworkers find the perfect meeting location. After their ideas were solidified, student groups identified their backlog (the load of work to be completed in the future) and completed a series of three sprints.

ClassGo

The application created by Jacob Hiban, Vivian Ng, and Stephanie Okereke titled, ClassGo, is a buying and selling platform tailored to Pace students. Users can buy or sell used classroom supplies like textbooks, lab materials, and more. The application features a homepage, search bar, selling and buying pages, and a capability to “favorite” the items the user likes best. Future improvements for the application include an updated user interface, homepage, chat, commenting section, and notification settings. These computer science mavens hope that their app can one day be a service that Pace students will choose to use over eBay, Mercari, or even Poshmark.

Kitten Klub

The makers behind Kitten Klub ask, “kittens and alcohol!? Who knew?” Well, they did! The application is a time management game set in the world of cats which was created by Samuel Gellar, Nicholas Vallarelli, Sammy Chen Li, and Anna Marinina. Targeted users play the game by creating drinks for the kittens they are bartending for. The game, which is only available for Apple devices at the moment, has nine levels that increase in difficulty.

EzAttend

The goal of EzAttend is to simplify the attendance taking process. Contributors, Edward Gervis, Raami Sharif, and Ian Groombridge worked together to make a one tap attendance app using Bluetooth. The application allows the teacher to create a class and take attendance, while also allowing students to see their attendance record.

 

Royal Closet

Royal Closet is tailored to the user. The fashion application captures user information, user market recycler view, avatar choice, and measurement comparisons to show the user what a chosen item of clothing could look like on their body by placing a version on their tailored avatar. Krutika Wadha, Tiara Hammond, and Yunting Yin designed this app to help individuals make fashion choices. They hope in the future to make it an inclusive e-commerce app with customizable avatars.

Lumattica

Lumattica is all about “putting color back into the world,” according to creators Austin Halper, Justin Sciglimpaglia, and Aayan Jalal. The app targets people who suffer from color blindness. The app works for both yellow-blue and red-green color confusion. Features include a field view, self-diagnosis, camera, and color quiz.

 

 

Lovescope: The Astrology Dating App

Lovescope: The Astrology Dating App is exactly what it sounds like. It’s a dating app specialized to each astrology sign. Creators Margarita Dominguez, Nick Krawczeniuk, Jennifer Rhau, and Minying He created the application to give users explanations of all planets, houses, and signs. The app integrates user profiles so users can create their own birth chart (gender options include non-binary) and uses a compatibility algorithm to see which users match together best!

translatAR

Yuliya Daroshka, Ivan Tang, Brandon DeLuca, and Jeffrey Cruz are the minds behind translatAR: an app that has the potential to be a direct competitor to Google lens. Its target audience is English speakers who travel abroad each year. The straight forward visual translator app is capable of helping users find the correct word for any object they take a picture of in 26 languages!

 

Fuse

“Meeting up with friends just got a whole lot easier,” according to the minds behind Fuse. The app helps groups meet up at a central and convenient location for all users. Creators Stephan Reyes, Manan Thakkar, Stephanie Philip, Kito Beriens, and Vincent Ajodhia created this app with multiple APIs to incorporate map and group-chat features. Whether a group wants to meet at a restaurant, bar, or park, this app helps them find the best option. This app solves all of those “where should we meet” problems by giving a solution that fits everyone’s needs.

These projects are all products of hard work and collaboration. Make sure to check out each app to fully experience how they function overall by scanning the QR codes on each poster. We’re proud of these software engineering students and what they created in just one semester.

The Design Factory is the hub of innovation for students at Seidenberg

Pace University’s Design Factory students are always working on global problems that need innovative solutions. The students are teamed up, then have the opportunity to brainstorm and use “design thinking” methodology to take an idea from the drawing board to a working prototype. These students aren’t just dreaming of being the next wave of innovators, they already are.

Laina Posner—a Pace University junior majoring in computer science—has been a summer intern at UPS, a Grace Hopper Conference attendee, and a Pace University Nexus Maximus team member. She is also a design factory student who had the opportunity to go to Helsinki, Finland in October at the Aalto University Design Factory.

“I’ve been working with [the Design Factory] for the past two years, because that’s when [it] officially launched,” Laina states.

Of the Design Factory process overall, she explains: “It’s a big collaboration between different schools all over the country and also the world, but then also different majors as well. So each time I was assigned a project with a different team and I was always given a different task, so it was a great opportunity to become experienced in lots of different things.”

Last semester, Laina had the chance to start working on the PdP team with a start-up company. When she traveled to Finland, she had the opportunity to hear about what her team would be doing for the rest of her junior year.

“When I met them in September, we got a demo, met the team, and met the company. When we go back in May, we will be able to present our product. We’ll be able to see [the process] from start to finish. I’m working on the application part of it where I’ll be designing software to improve the already existing product that they have. Our other teammates will be working on the prototype,” she explains. “Right now I’m assigned on a permanent project where I’ll be working over the year, I’ll be working with a team from Finland with also NYC students. Our project is to work to create a prototype for a company. Our company is Pexray Tech, and they’re looking for a new innovation.”

Pexray Tech is a company that builds portable X-ray systems. The company is looking for a new project, so Laina and the rest of the team are at the forefront of that. The team has completed the beginning stages of the project where planning, research, and getting acquainted with one another is essential.

“It was really cool to have a connection with people that I had really never met over a product for a company that I was just introduced to. We’ve been able to work together since we met for the project, and building connections with other people was really cool,” she states.

Over the past few months, Laina and the rest of the team focused on using “design thinking” to build a working prototype for Pexray Tech. Currently, the team has two months left to create a product for Pexray Tech.

“We are current prototyping our project and in the developmental phase,” Laina explains.

Over the next two months, the team will finalize their product and have the chance to present it to the company. It will be a showcase of their hard work and innovation on a real-world solution.

Now, Laina just wants others to know about the opportunities one can gain through the Design Factory experience. While some students have been working with the Design Factory team for years, they’re always looking to recruit more students. They want more innovators and dreamers who can create solutions to real-world problems with real clients.

“It was very selective, so a lot of people didn’t know about it,” Laina stated of the application process. “I think a lot of students after I told them about it are very interested in it. I wish more people knew about it and more people could experience it, too.  It is an amazing experience. Students are able to use their own personal knowledge of the field and implement their work into a project that they have worked on from start to finish.”

We’re hoping to get the word out about  Pace University’s Design Factory and to get more students aware of this opportunity to innovate! If you’re interested in applying to be a design factory student, sign up for the mailing list!

Battle of the Bots at Pace University

If watching robots compete to complete tasks entices you, then you should’ve been at Pace University on February 10th. The 10th annual Hudson Valley NY FIRST Tech Challenge championship robotics tournament was held on Pace University’s Westchester campus. The day was full of challenges and innovation for middle and high school students from the Hudson Valley. Only one goal stayed in each of the students’ minds throughout the tournament: getting to the world championship.

The event, run by Dr. Richard Kline and Jill Olimpieri, hosted 27 high school-level teams. The competition brought together the region’s top qualifying teams and their robots to compete in a task-based challenge. Pace University has hosted the regional championship for several years.  Pace University, Pace University Athletics, and IBM sponsored the event.

According to the Hudson Valley NY FIRST Tech Challenge site, “Students in FTC design and build a robot using aluminum, polycarbonate, motors and servos, sensors, and a variety of other materials. They program and control it using Android Smartphones with Java or a Blocks-based graphical language.”

With exclusive scholarships open to competing students totaling more than $80 million, the stakes were high. The challenge to beat this year was “Rover Ruckus,” and teams battled to take the top spots.

According to Dr. Kline, “More than 40 current Pace students and about a dozen alumni, staff, and faculty participated in the event, comprising half of the 100 or so volunteers who banded together to run the competition under the guidance of volunteer coordinator and Seidenberg School staff member Jill Olimpieri. Students contributed in all areas of the competition, from setup and logistics to referees, judges, inspectors, and robot technical advisors.”

Pace students and faculty Sukun Li and Leanne Keeley volunteered as judges for the event. Students Jeana Cosenza, Kyle Hanson, Joel Thomas, and Zach Demeglio, among others, volunteered in various supporting roles. Dean Hill even made a special appearance to cheer on the teams and robots!

Fios 1 News covered the event, giving the young students the chance to feature their efforts on the local news. The coverage inspired and motivated the students to share their experiences and do their best.

At the end of the day, three teams came out on top and will move on to the world championship. Congratulations to Team 6567 – Roboraiders from Red Hook High School, Team 7486 – Suffern Robotics from Suffern Senior High School, and Team 8397 – Beta, from CCE Clinton County 4-H. We wish the best of luck to them at the world championship!
