Abstract: A method according to embodiments of the present disclosure includes generating a multi-classification label set corresponding to an object set based on a binary classification label set corresponding to the object set. The method further includes receiving an embedding vector set from a non-label party model, wherein an embedding vector in the embedding vector set is generated based on a feature of an object in the object set. The method further includes generating a label party model based on the embedding vector set and the multi-classification label set, wherein the label party model includes a first network and a second network. The method according to embodiments of the present disclosure enables a label party to protect privacy of an original label set under the condition of joint training with a non-label party, and prevent the non-label party from inferring original labels corresponding to original features by various means.
