mental-health-mistral-7b-instructv0.2-finetuned-V2
This model is a fine-tuned version of mistralai/Mistral-7B-Instruct-v0.2 on the mental_health_counseling_conversations dataset.
It achieves the following results on the evaluation set:
- Loss: 0.6432
Model description
A Mistral-7B-Instruct-v0.2 model finetuned on a corpus of mental health conversations between a psychologist and a user.
The intention was to create a mental health assistant, "Connor", to address user questions based on responses from a psychologist.
Intended uses & limitations
Intended to be used as a mental health chatbot to respond to user queries.
Training and evaluation data
The model is finetuned on a corpus of mental health conversations between a psychologist and a client, in the form of context - response pairs. This dataset is a collection of questions and answers sourced from two online counseling and therapy platforms. The questions cover a wide range of mental health topics, and the answers are provided by qualified psychologists.
