AI prompts can be used to enhance machine learning models by providing specific suggestions, generating training data, improving model interpretability, automating hyperparameter tuning, and facilitating model debugging and error analysis. AI prompts guide users in creating high-quality datasets, identifying relevant features, optimizing model performance, and addressing bias and fairness concerns. They can also aid in generating synthetic data, fine-tuning pre-trained models, speeding up experimentation cycles, and explaining model predictions, leading to more efficient and accurate machine learning outcomes.
