摘要： Embodiments of the present disclosure relate to a method, apparatus and computer-readable storage medium for data processing. The method may comprise: obtaining feature data for characterizing a plurality of factors of a user set, the plurality of factors comprising a target factor. The method may further comprise obtaining a condition factor from the plurality of factors based on the feature data, the obtained condition factor being a cause of the target factor. The method may further comprise determining a user having the condition factor from the user set. According to the technical solution of the present disclosure, accurate user positioning and strategy formulation may be realized based on the discovery of a high-dimensional causal structure. In addition, according to the technical solution of the present disclosure, information such as the user's satisfaction degree can be simulated without performing cumbersome and inefficient questionnaire surveys.

摘要： Embodiments of the present disclosure relate to a method, a device and a computer-readable storage medium for data processing. The method for data processing comprises: obtaining a set of observation samples regarding a plurality of factors, one of the set of observation samples comprising respective observed values of the plurality of factors. The method further comprises: estimating, for each of the plurality of factors and based on the set of observation samples, a distribution that differences between observed values of the factor and estimated values of the factor follow. The method further comprises determining, based at least on the estimated distribution, a causal structure representing a causal relationship among the plurality of factors. Embodiments of the present disclosure further provide a device and a computer-readable storage medium for implementing the above method. The embodiments of the present disclosure can accurately and robustly discover the causal relationship among a plurality of factors without making any assumptions about the relationship between the data distribution and the factors, and affect the observed value of the target factor based on the causal relationship.
