Machine Learning Engineer Intern Cover Letter Example

Dear Dr. Lee,

I am thrilled to apply for the Machine Learning Engineer Intern position at Argo AI. As an AI enthusiast with a strong background in machine learning and a passion for autonomous vehicles, I couldn't imagine a more exciting opportunity than contributing to Argo AI's mission of building the world's best self-driving technology.

During my previous internship at Resume Worded, I worked on developing a computer vision model for detecting and classifying road signs. By leveraging transfer learning and fine-tuning a pre-trained CNN, I was able to improve the model's accuracy by 15% while reducing inference time by 20%. I also have experience with popular machine learning frameworks such as TensorFlow and PyTorch, and have completed several projects, including building a recommendation system that increased user engagement by 30%.

What excites me most about Argo AI is your commitment to safety and your focus on developing robust and reliable autonomous driving systems. I am particularly interested in your work on sensor fusion and how you combine data from multiple sensors to create a detailed understanding of the vehicle's surroundings. I believe my strong technical skills, coupled with my ability to think creatively and my passion for autonomous vehicles, would enable me to make valuable contributions to your team.

I would welcome the opportunity to discuss further how my skills and experience align with Argo AI's needs. Thank you for considering my application, and I look forward to the possibility of joining your team and contributing to the future of autonomous driving.

Sincerely,
[Your Name]
