“…Quantum machine learning has also been used to classify genuine quantum data. Some prominent examples of such applications include: classifying phases of matter [47], quantum channel discrimination [23], and entanglement classification [20]. Other machine learning problems with quantum mechanical origins that have been solved by variational algorithms include quantum data compression [36] and denoising of quantum data [7].…”

A tensor network is a type of decomposition used to express and approximate large arrays of data. A given dataset, quantum state, or higher-dimensional multilinear map is factored and approximated by a composition of smaller multilinear maps. This is reminiscent to how a Boolean function might be decomposed into a gate array: this represents a special case of tensor decomposition, in which the tensor entries are replaced by 0, 1 and the factorisation becomes exact. The associated techniques are called tensor network methods: the subject developed independently in several distinct fields of study, which have more recently become interrelated through the language of tensor networks. The tantamount questions in the field relate to expressability of tensor networks and the reduction of computational overheads. A merger of tensor networks with machine learning is natural. On the one hand, machine learning can aid in determining a factorisation of a tensor network approximating a data set. On the other hand, a given tensor network structure can be viewed as a machine learning model. Herein the tensor network parameters are adjusted to learn or classify a data-set. In this survey we review the basics of tensor networks and explain the ongoing effort to develop the theory of tensor networks in machine learning.
