    For what it’s worth, my second year of PhD was relatively miserable compared to my first and third. ignore the prestige games, knuckle down and do the best work you can do- it’s mo…

    That’s not mathematically accurate though, is it? We haven’t reduced the dimension of the vector by one. Pray tell, which dimension do we lose when we normalize, say a 2D vector?

    Magnitude is not a dimension, it’s information about each value that is lost when you normalize it. To prove this normalize any vector and then try to de-normalize it again.

    Interesting, I hadn’t heard of two tower modes before! Yes, I guess it’s curious that the information lost doesn’t seem very significant (this also matches my experience!)

    They're poor at recollecting the exact descriptions of the ~150,000 ICD codes, which is why these other approaches [1,2] give the known information (codes) in some way to the model…
