Hi, I’m Tal!

I’m a Ph.D. candidate at the Technion, Israel Institute of Technology, in the Electrical Engineering Department, under the supervision of Prof. Aviv Tamar.

My research revolves around (Deep) Unsupervised Learning, Reinforcment Learning and Robotics, and it is done under the RL^2 lab, which is a part of the Control, Robotics and Machine Learning (CRML) lab.

I received my BSc (Cum Laude) and MSc (Summa Cum Laude) both in Electrical Engineering from the Technion, where the topic of my MSc thesis was “Deep Variational Semi-Supervised Novelty Detection”, also done under the supervision of Prof. Tamar.

During my time at the Technion, I’m also a teaching assistant in Machine Learning courses, for which I have written theory-based and hand-on tutorials which you can access in the “Teaching” section.

I teach several courses at the Technion, and I make my materials available on GitHub to everyone. All the tutorials include theory (with a lot of math) and code (Python), and are in a Jupyter Notebook format (which I really like!), but there is also a PDF version available. For the deep learning parts, PyTorch is my framework of choice.
