Mathematical Notation for a Classifier in a Text Classification System

Example of Text for Polarity Classification

A system is designed to classify customer reviews as 'positive' or 'negative'. The system operates in two stages: first, a component converts the review's text into a detailed numerical vector that captures its meaning. Second, another component takes this vector as input, calculates a score for the 'positive' label and a score for the 'negative' label, and then outputs the label with the higher score. If this system processes the review 'The service was impeccable!', which component is directly responsible for the final decision to label the review as 'positive'?

A system is designed to determine if a movie review is 'positive' or 'negative'. Arrange the following steps in the correct logical order, from the initial input to the final output.

Example of a Prediction in Polarity Classification

A model, which has been specialized for a text classification task, processes a new input and produces the following probability distribution over three possible classes: {"Bug Report": 0.15, "Feature Request": 0.75, "General Inquiry": 0.10}. Based on this output, what is the model's final prediction?

A language model has been specialized to classify customer support tickets into categories like 'Billing Issue', 'Technical Support', or 'Account Question'. Arrange the following steps in the correct sequence to describe how this model would process a new, unseen customer ticket to make a prediction.
