+# ZhiXin_embedding
+
+<!-- Provide a quick summary of what the model is/does. -->
+This model contains the fine-tuned retrieval embeddings of the ZhiXin model. For the fine-tuned model, see ```ZhiXin_model```.
+
+ZhiXin, introduced in the paper ```ZhiXin – A RAG-based Virtual Assistant for Persons with Intellectual and Developmental Disabilities```, is a Retrieval-Augmented Generation (RAG) language model system specifically tailored to support parents of children with intellectual and developmental disorders. The core component of ZhiXin is a fine-tuned language model based on the ```Qwen2-7b-Instruct``` model. Leveraging Supervised Fine-Tuning (SFT) techniques, this specialized LLM has been trained to understand and address the unique challenges faced by parents and caregivers, providing relevant, empathetic, and reliable guidance.
