# TwinTransitionMapper_AI
This repository contains the model for our paper entitled [Not all twins are identical: the digital layer of “twin” transition market applications](https://drive.google.com/file/d/1MN0GSl1FExHYkDyN_VhEt8yFwMX1MM4x/view?usp=drive_link) which is under review in Regional Studies (https://www.tandfonline.com/journals/cres20).

This is a [SetFit](https://github.com/huggingface/setfit) model that can be used for Text Classification. This SetFit model uses [intfloat/multilingual-e5-large](https://huggingface.co/intfloat/multilingual-e5-large) as the Sentence Transformer embedding model. A [LogisticRegression](https://scikit-learn.org/stable/modules/generated/sklearn.linear_model.LogisticRegression.html) instance is used for classification.

The model has been trained on paragraphs from German company websites using an efficient few-shot learning technique that involves:

1. Fine-tuning a [Sentence Transformer](https://www.sbert.net) with contrastive learning.
2. Training a classification head with features from the fine-tuned Sentence Transformer.

The model is designed to predict the AI capabilities of German companies based on their website texts. It is intended to be used in conjunction with the [Twin_Transition_Mapper_Green model] (https://huggingface.co/LKriesch/TwinTransitionMapper_Green) to identify companies contributing to the twin transition in Germany. For detailed information on the fine-tuning process and the results of these models, please refer to the [paper](https://drive.google.com/file/d/1MN0GSl1FExHYkDyN_VhEt8yFwMX1MM4x/view?usp=drive_link).
