Recommendation: You make use of Recurrent Neural Networks (RNNs).
Will the requirements be satisfied?

  • A. Yes
  • B. No


Answer : A

Note: RNNs are designed to take sequences of text as inputs or return sequences of text as outputs, or both. Theyג€™re called recurrent because the networkג€™s hidden layers have a loop in which the output and cell state from each time step become inputs at the next time step. This recurrence serves as a form of memory.
It allows contextual information to flow through the network so that relevant outputs from previous time steps can be applied to network operations at the current time step.

You have been tasked with evaluating the performance of a binary classification model that you created.
You need to choose evaluation metrics to achieve your goal.
Which of the following are the metrics you would choose? Answer by dragging the correct options from the list to the answer area.
Select and Place:



Answer :

The evaluation metrics available for binary classification models are: Accuracy, Precision, Recall, F1 Score, and AUC.
Note: A very natural question is: ג€˜Out of the individuals whom the model, how many were classified correctly (TP)?ג€™
This question can be answered by looking at the Precision of the model, which is the proportion of positives that are classified correctly.
