|machine learning by tensor network and quantum computing
it is a critical challenge to simultaneously gain high interpretability and efficiency with the current schemes of deep machine learning (ml). tensor network (tn), which is a well-established mathematical tool originating from quantum mechanics, has shown its unique advantages on developing efficient “white-box” ml schemes. here, we give a brief review on the inspiring progresses made in tn-based ml. on one hand, interpretability of tn ml is accommodated with the solid theoretical foundation based on quantum information and many-body physics. on the other hand, high efficiency can be rendered from the powerful tn representations and the advanced computational techniques developed in quantum many-body physics. with the fast development on quantum computers, tn is expected to conceive novel schemes runnable on quantum hardware, heading towards the “quantum artificial intelligence” in the forthcoming future.
