I am doing PhD in AI field mainly in NLP
my supervisor told that I have to contribute something new to the field.
OK, I started doing some trails in improving one case in the field of NLP AI
I found a way that can improve that case in 80% of the times.
I don't want to go into the details of the method that I found, as it is mainly technical.
Anyway, I told my supervisor about what I found and he wasn't impressed.
The things he mentioned that this method is not provable, which means it is proved only by trying the cases without mathimatical prove.
is this enough for PhD or shall I prove it mathematically?
