Dueling Deep Q-Network Agent

ML Framework: TensorFlow 2.2.0

May 24, 2020

Dueling deep Q-network (DQN) agent for training/playing classical control environments of OpenAI Gym. The agent can be adapted to interact with similar environments, i.e. with discrete action space etc., by changing a few lines of code.

About me



Dr. Taner Esat

Quantum Physicist &
Machine Learning Enthusiast

My name is Taner Esat. I am a researcher in the institute for Quantum Nanoscience at the Forschungszentrum Jülich and work in the field of quantum technology. My research focuses on the manipulation of the electronic and magnetic properties of matter, e.g. single molecules and atoms with scanning probe microscopy techniques, and their use for quantum information processing. I have strong background in mathematics and computer science. In addition, I have keen interest in machine learning and artificial intelligence. Among other things I use modern machine learning techniques for data analysis and for the automation of my experiments, e.g. computer vision and reinforcement learning.

In 2018/2019 I worked as a postdoc in the group of Andreas Heinrich at the Center for Quantum Nanoscience (Seoul, South Korea), where I focused on electron spin resonance and pump-probe measurements on single atoms on surfaces. Furthermore, I was a visiting researcher in the group of Christopher Lutz at IBM Almaden (San Jose, California, USA) in 2019. During my stay at IBM I measured Rabi oscillations, Ramsey fringes, and spin echo on individual magnetic atoms.

I obtained my PhD (Dr. rer. nat.) from the RWTH Aachen University in 2017 for my work at the Forschungszentrum Jülich, where I studied the magnetic interaction between molecules and their environment using scanning probe techniques under the supervision of Ruslan Temirov and Stefan Tautz. Previously, I studied physics at the Heinrich Heine University Düsseldorf and worked on quantum optics. In particular, I investigated magneto-optical traps for optical clocks and monolithic resonators for laser systems during my Bachelor and Master thesis in the groups of Axel Görlitz and Stephan Schiller, respectively.
