Default Re: doubt in lecture 11, deterministic noise

There are two factors here: the level of deterministic noise, and the complexity of the hypothesis set used to fit the data. Both of these factors are affected by having the target fixed while expanding the hypothesis set. The two effects push overfitting in different directions.

If you want to see the impact of deterministic noise by itself, without having another factor that affects overfitting in play, you should fix the hypothesis set and increase the complexity of the target function.
Where everyone thinks alike, no one thinks very much
