Yekta Demirci

Hi! I am a second year Software Eng. MASc candidate at University of Waterloo where I am advised by Prof. Mahesh Tripunitara and Prof. Catherine Rosenberg. My research focuses on Service Level Agreement (SLA) enforcement in software defined Radio Access Network (RAN) settings.

Before starting to the graduate school, I completed my undergraduate studies in Electrical and Electronics Engineering at Middle East Technical University where I specialized on telecommunication option in my final year and took extra classes from the Computer Engineering.

During my undergraduate studies, I had exchange programs at NTU (Singapore) and KAIST (Korea). Outside of work, I highly enjoy cooking, hiking and camping.

Research

My current research interests lie in software engineering and radio access networks.

During my last summer internship, I had a chance to have research experience on machine learning at GEMSEC lab under the supervision of Prof. Mehmet Sarikaya . Further information about the project is available here.

Projects
foodHunter

Food Hunter Web Application 3 months-5 people

As a group of five people, we used agile methods to develop a web application as a course project where we used MongoDB, Google maps and web crawling APIs as well as HTML, CSS, JS and Python (Selenium for testing). We implemented unit, integration, system and acceptance tests. In order to provide a user friendly interface we designed a single page with three sliding bars. The website takes location and ingredients as inputs and it offers some meals.

fashion MNIST

Feature extraction and CNN on Fashion MNIST dataset 1 month-2 people

For the ECE657A Data & Knowledge Modeling and Analysis course, first we used some feature extraction methods (PCA, LDA, Isomap, LLE and t-SNE) and trained some classical ML models (Decision Tree, SVM, KNN). Then we trained a Convolutional Neural Network model and compared the results of two different approaches.

http classification

Flow level, HTTP-2 Classification with Machine Learning Algorithms 2 months-individual

For the CS656 Computer Networks course, I trained various machine learning models (KNN, SVM, CART, ANN) to predict HTTP2 flows from its predecessor HTTP1. Firstly, I constructed a flow level data-set using a publicly available web traffic collection, then I used several features including HTTP version to make ground truth via deep packet inspection and finally I pre-processed the data (PCA, LDA), trained various ML models and classified HTTP traffic with +90% accuracy. Confusion matrices of each model can also be seen under the project report.

multi threading

Performance Analysis of different Vertex Cover (VC) Approx. Algorithms via MultiThread 3 weeks-2 people

We used three different approaches to solve minimum VC problem. Firstly we followed polynomial time reduction to CNF-SAT approach using minisat library. Secondly, as an approximation, we picked the vertex of highest degree and removed all the incident edges. Finally, again as an approximation, we picked an edge randomly and added its vertices to the VC. We run all the approaches concurrently using multithreading to compare time performance metric.

social network analysis

Betweenness (modified BFS) Analysis Over a Social Network 10 days-individual

For one of my admissions, I was asked to choose a publicly available dataset and form some hypotheses. I chose a Facebook dataset and questioned the following hypotheses: (i) "Number of friendships in a social network do not vary much between the individuals" (ii) "People whom have high number of friends tend to connect different communities". I used basic statistical tools for the first hypothesis whereas for the second one I implemented a (highly) modified BFS algorithm and found betweenness of connections (edges) between the individuals.

image processing

GPU programming with Jetson TX2 device in CUDA & C++, Real Time Edge and Ball Detection 2 months-2 people

I implemented matrix addition and multiplication scripts in .cu as an introduction to GPU programming. After that we implemented a canny edge detector in real time using built-in libraries of CUDA with a simple User Interface (UI). A user could change some filtering variables (e.g blur sigma, blur window size etc.) on the fly. Then we implemented another application that detects green balls again with built-in CUDA libraries. It also provides a simple UI to adjust different variables on the fly.

map extraction robot

Design and Implementation of an Autonomous Map Extraction Robot 6 months-5 people

For the final year capstone project, with a group of five people we designed and implemented an autonomous map extraction robot. The robot is randomly deployed in an enclosed area where it extracts the map and identifies the objects with their centre locations. I focused on the noise filtering, (novel) path finding and object clasification algorithms.

Implementation of FFT and Overlap & Save Algorithms with myRIO Device 2 weeks-2 people

For the term project of real-time digital signal processing course, we implemented FFT and overlap & save algorithms in C, compiled and run with myRIO device that operates on Linux based Real-Time OS.

gemsec

Metal Binding Peptide Prediction Summer research internship

I had a chance to have my final summer internship at University of Washington , GEMSEC lab . During my internship I implemented an application that takes some existing metal binding peptides as input and predicts some new possibly metal binding ones. We created different tensor cuts using location, property and peptide then used PCA, wavelet transforms and several clustering algorithms to understand the correlation between metal binding and some other properties. I coded the application step by step which pre-processes the data, creates different cuts and makes the predictions in Python, +1000 lines

NBA Play-off & Regular Season Relation Analysis with PCA & Artificial Neural Nets 1 month-4 people

CENG:499 Introduction to the Machine Learning was the first course I took from the computer engineering department as extra curriculum. For the final project, we extracted publicly available 2016-2017 NBA data using BeautifulSoup, then used PCA for data preprocessing and trained a few ANN models.
