Background: CS Undergrad applying to CS PhD Programs.
I have an internship experience under a HOD of a department in my university. The work was on computer vision, there was a paper published at a decent venue (I am a shared first author) and some good publicity as well.
I do not have space left in my sop to mention this as my primary target is deep learning and I mentioned all my deep learning experiences. But, my work is applying deep learning to computer vision problems.
Questions: Should I submit a LOR from this prof? Who's work I do not mention at all in the SOP (It is mentioned in my CV)
Why I want to: Because she is a HOD and the work was done in collaboration with a foreign university so she can highlight that exposure as well given I am from India and applying to a foreign country.
Note: This will be my additional LOR. Few programs all 3+1 or 3+2. This will be my +1. I already have submitted the primary 3.
