• Identification of potential lncRNA–protein interactions (LPIs) contributes to understand many important biological processes and progression and metastasis of various complex diseases.
• Under an ensemble learning framework (EnANNDeep) composed of adaptive k-nearest neighbor classifier and deep models including deep neural network and deep forest, this study focuses on systematically finding underlying linkages between lncRNAs and proteins.
• EnANNDeep computes the best average AUCs and AUPRs, indicating its superior LPI prediction ability.
