Experience

Visiting Research Intern

Universite de Montreal
May 2023 - Present · 3 years 2 months

• Further development of Artificial Sign Language with Tensorflow-GPU through Professor Houari Sahraoui.
• Trained deep learning models (including Dense Neural Networks, CNNs, transfer learning w/ YOLO + ResNet, and
LSTM w/ Tensorflow) to translate American Sign Language to English.
• Implemented an algorithm to detect and encode body signs into skeleton (with OpenCV and MediaPipe).
• Webscraping tutorials of American Sign Language (using BeautifulSoup and C++) to extract 1000 hand signs (30
gb of videos, treated w/ OpenCV, Numpy and C++!)
• Performed data augmentation (by a factor of x128) (with C++, Numpy and Pandas) to obtain the largest
dataset for ASL in the world.
