Automatic correction of MCQ exam papers implemented in MATLAB.
MATLAB MCQ Exam Corrector
A project that uses user's brain signals to control a computer, implemented in PyQT.
The project uses Steady State Visually Evoked Potential (SSVEP) to implement an on-screen assistive keyboard. SSVEP are signals that are natural responses to visual stimulation at specific frequencies. When the retina is excited by a visual stimulus, the brain generates electrical activity at the same (or multiples of) frequency of the visual stimulus. By flashing a finite set of areas on the screen, one can determine which area was of interest to the user by comparing the frequency of the brain’s electrical activity, and hence use it for taking an action (e.g. keyboard character selection). The keyboard's efficiency is improved using the autocomplete feature. The system is also able to predict the user's intent using a Natural Language Processing (NLP) technique and feeding the result to a customizable set of bots that assist the user.

Within this project we searched for experienced professional software developers or system administrators to fill out a survey. Working with this freelancer was exactly what we were looking for! Working with them helped us a lot with our research project. The communication in advance as well as the survey participation were extremely satisfactory and highly professional. Thank you very much for the opportunity to learn from your experiences.

Comparative Study of Visual Question Answering Algorithms

IEEE
In this study, we compare the performance of state of the art VQA algorithms on different VQA benchmarks. Each benchmark is more effective at testing VQA algorithms on different levels. Some datasets challenge the algorithms to perform complex reasoning steps to arrive to an answer. Other datasets might challenge algorithms to retrieve external world knowledge to answer the posed questions. We categorize the algorithms by their main contributions into 4 categories.
