Abstract

The sparsity problem could result in a data-dependent reduction and we couldn’t do rough set null value estimates, therefore, we need to deal with the problem of a sparse data set before performing the null value estimate and padded by introducing a collaborative filtering technology used the sparse data processing methods - project- based score prediction in the study. The method in the case of the object attribute data sparse, two objects can be based on their known attributes of computing the similarity between them, so a target object can be predicted based on the similarity between the size of the other objects to the N objects determine a neighbor collection of objects and then treat the predicted target unknown property by neighbors object contains attribute values to predict.
