Abstract:
Recent advances in machine learning (ML) and quantum computing (QC)
hardware draw significant attention to building quantum machine learning (QML)
applications. One of the challenges is that the scale of existing quantum devices is small
and special methods are required to preprocess or compress the large-dimensional
inputs. The choice of such dimensional reduction method plays a crucial role in the
performance of QML. In this talk, I will first provide a quick overview of the hybrid
quantum-classical machine learning paradigm. Then I will present the recent progress of
tensor network (TN) based dimensional reduction methods used in QML. Specifically,
the hybrid TN-VQC models in both supervised learning (classification) tasks and
reinforcement learning will be described. Potential advantage and scalability in the
NISQ era will be discussed as well.

Biography Brief:
Dr. Yen-Chi Chen received the Ph.D. and B.S. degree in physics and the M.D.
