Week3 - Beam Search Error Analysis

Course Q&A Deep Learning Specialization Sequence Models

In the error analysis process described in the lecture ( minute ~4:20)
we’re supposed to calculate and compare the conditional probabilities P(y|x) for y_hat and for y*.
The calculation should be done with the RNN network. But I am not sure I understand how?

y is not given to the RNN , the RNN needs to figure it out. How can we calculate a probability for a given output y?

I think there is an answer for this posted on the Forum recently. Try a search using the term “beam search”.
