This model is designed for generating sentence embeddings for English text, particularly in the financial domain. It can be used for various natural language processing tasks such as semantic search, clustering, and information retrieval.
The model was fine-tuned on the sujet-ai/Sujet-Financial-RAG-EN-Dataset. This dataset consists of question-context pairs in English, focusing on financial topics.
The model was evaluated using the InformationRetrievalEvaluator on the test split of the sujet-ai/Sujet-Financial-RAG-EN-Dataset.
The model is specifically trained on English financial texts and may not perform optimally on other domains or languages. Users should be aware of potential biases present in the training data.
