Prompting LLMs for Data Science.md

A developer has compiled a list of 20 prompts for using large language models (LLMs) in data science tasks, covering model training, hyperparameter tuning, time series forecasting, handling imbalanced data, feature importance, model explainability with LIME and SHAP, feature engineering, data exploration and generation, visualization, code writing, and translation between programming languages and database systems.
