I know that in a scientific paper or thesis made by a single author, it is common to use we. (This is also recommended at our university.)
But what about when you alone are presenting a thesis work orally?
At first glance, it is quite odd to use we when the work is written only by you yourself and you are presenting it alone.
For example, saying:
We will present you my machine learning model…
while at the same time you stand alone in front of the examiners seems very strange to me.
Is this style of presentation expected, tolerated, or forbidden?
We will be presenting my machine learning model,
is completely wrong. When you are writing a thesis, you would use we instead of I and our instead of my. The we combined with the my doesn’t work. Similarly, this combination doesn’t work when giving an single-presenter oral presentation. It implies that several people are speaking, but somehow that only one person came up with the machine learning model.
In an oral presentation, you should use I when you want to refer to yourself as the person giving the presentation. For your work, you can either use I/me/my or we/us/our. If it was joint work with somebody else, definitely use we/us/our. If it’s your own single-authored work, I think using I/me/my is more common, but I don’t think anything is wrong with using the scientific we/us/our.
So in an oral presentation, you should say one of:
I will be presenting my machine learning model,
I will be presenting our machine learning model.
