Claim 19:
20. A non-transitory computer readable storage medium with computer instructions stored thereon, wherein the computer instructions are used for causing a method for discovering causality from data, wherein the method comprises:
acquiring to-be-processed data which is body data corresponding to different users, and obtaining a covariance matrix of the to-be-processed data;
determining a first target column in the covariance matrix, taking the number of columns of the first target column as a first place in a rearrangement sequence, and obtaining a first upper triangular matrix according to the first target column;
determining a position of the number of columns of the covariance matrix other than the first target column except the first place in the rearrangement sequence according to the first target column and the first upper triangular matrix, and obtaining an upper triangular matrix in each position determination;
obtaining an adjacency matrix according to an upper triangular matrix and a rearrangement sequence obtained in final position determination; and
generating a directed acyclic graph (DAG) by using the adjacency matrix, and taking the DAG as a causality discovery result of the to-be-processed data.
