哪三項是行銷人運用機器學習時所能貢獻的技能？(請選擇三項)

Marketers contribute to machine learning by setting clear goals for campaigns, which guides the algorithms' optimization. They also provide creative assets (e.g., ad copy, images, videos) that the machine learning system tests and optimizes for performance. Finally, marketers define the overall marketing strategy, including target audiences and messaging, which informs how machine learning is applied to achieve business objectives. While machine learning can enhance scale and efficiency, these are outcomes or benefits of using machine learning, not direct skills marketers contribute to its operation.
