Balaji,
In a previous reply, in a different course, months ago, you said this:
If you see a case where the course videos / ungraded labs don’t contain sufficient information for answering a quiz question, please provide the link to the quiz & quiz question.
I have not seen this lately in the quizs per se – e.g., there have been some interesting wordings that can’t be answered directly but can be answered by process of elimination. The quiz for this week has one of those questions.
However, if I extrapolate your original comment to include the assignments then I would have to say, for this week’s assignment, the expected solution of the fit_label_encoder section and the use of tf.keras.layers.StringLookup was a bit of a sandbagging. It can be solved by using learning transfer from the use of tf.keras.layers.TextVectorization() but it really is something that was not discussed directly.
It forces the student to the reference docs, which they need to understand, but those docs are a bit terse and you can lose some time reviewing all the options that don’t apply.
