Greetings,
I am a bit confused by the documented formula for the negative log-likelihood loss:
NLLL766×242 35.6 KB
What are those x_(n,y_n) ? They say x is the input, but the loss is not calculated from the input. A loss should be calculated from the output and the target, should it not?
Best,
PiF
edit: is the following assumption correct?
x_(n,y_n) is the entry of the network output vector that corresponds to the probability of the target y_n, where n denotes the sample.
