My apologies. I rewrote it to be more formal this time. I removed contractions, used some more formal terms, added sincerely, and added Sir/Madam for the unknown recipient. I also added placeholders for [Student Name] and [Teacher Name] so they can be replaced to make the letter feel more personal and not like the teacher is distancing themselves from the student.

Dear Sir/Madam,

I am writing to you about a great student of mine I would like to recommend to your company, [Student Name]. I would like to stress that [Student Name] is fully autonomous. He is not at all remotely operated, or even semi-autonomous. As a company that uses deep learning, I am sure you can understand the significance of this.

[Student Name] not only got perfect scores on the final exam and a notoriously hard project in my class, but came up with novel solutions to problems that I never came across before in my research. I can definitely see them coming up with similar new solutions at your company, and I look forward to seeing what they will make there.

One example of [Student Name]'s creativity was a solution he orchestrated for an object tracking group project, which he led. First, [Student Name] scaled the image down and ran a CNN over that, then scaled it back up, translated the position to the scaled up image, and used crosshairs scanning both up and down as well as left and right along the object and its bounds to match the image histogram with the center of the scaled down image. This method was combined with another that used a video transformer with variable input size to predict where the input would be in the next frame, as well as a simpler method of approximating the trajectory of the object by matching it to a kinematic equation. All of these were combined into a DNN that used PPO to determine the best combination of outputs over time. It was quite complex, but it achieved the best results by far.

If you employ [Student Name] at your company, I am sure he will continue to build great solutions like that.

Sincerely,
[Teacher Name]
