# Model Card for: mmx_classifier_microblog_ENv02

Multi-label classifier that identifies which marketing mix variable(s) a microblog post pertains to.

## Model Details

You can use this classifier to determine which of the 4P's of marketing, also known as marketing mix variables, a microblog post (e.g., Tweet) pertains to:

1. Product
2. Place
3. Price
4. Promotion

### Model Description

This classifier is a fine-tuned checkpoint of [cardiffnlp/twitter-roberta-large-2022-154m] (https://huggingface.co./cardiffnlp/twitter-roberta-large-2022-154m). 
It was trained on 15K Tweets that mentioned at least one of 699 brands. The Tweets were cleaned and labeled using OpenAI's GPT4. 

Because this is a multi-label classification problem, we use binary cross-entropy (BCE) with logits loss for the fine-tuning. We basically combine a sigmoid layer with BCELoss in a single class.
To obtain the probabilities for each label (i.e., marketing mix variable), you need to "push" the predictions through a sigmoid function. This is already done in the accompanying python notebook.

IMPORTANT: At the time of writing this description, Huggingface's pipeline did not support multi-label classifiers.
