Abstract: A protein contact map is a simplified, two-dimensional version of the three-dimensional
protein structure. Protein contact map is proved to be crucial in forming the three-dimensional structure.
Contact map prediction has now become an indispensable and promising intermediate step towards
final three-dimensional structure prediction, while directed sequence-structure prediction hits
its bottlenecks. In this article, different evaluation scores of prediction efficiency are compared. Next,
the state of the art and future perspectives of contact map methods are reviewed and special attention is paid to those relying
on machine learning algorithms. Details of neural network based methods as well as a list of machine learning based
methods are given. Finally, bottlenecks and potential improvements of contact map predictions are discussed.
