摘要
•An ensemble-based co-training approach, named ECoRec, is proposed.•ECoRec process data from two or more different views to create a more robust model.•Our approach provide an enriched matrix that alleviate the sparsity and cold-start problems.•Results show that our strategy improves the overall system’s performance.
