Machine learning approaches

Definition

Machine learning approaches refer to computational techniques that enable computers to learn from and make predictions or decisions based on data, without being explicitly programmed. These methods are essential for analyzing complex biological data, particularly in understanding how protein structures relate to their functions, the hierarchical levels of protein organization, and the roles of non-coding RNAs in cellular processes.
