In this unit, we have seen that some natural language processing tasks may be accomplished with $$standard$$ multilayer perceptron neural networks, while others require specific neural networks like recurrent neural networks.

Which of the following tasks would you NOT be able to perform with a standard multilayer perceptron, and why? There may be more than one correct answer:

I. Detecting the sentiment in a customer product review on the Amazon website

II$.$ Translating text on a website from English to French

III. Categorising customer enquiries into the most suitable troubleshooting group $($technical support, billing, etc.$)$

IV$.$ Running an automated chatbot on a customer$-$facing company website

In each case, you can assume relevant training data is available for the task.
