This model is trained with modified alpaca-lora with lora + embed_tokens + lm_head be trained.
The dataset is from alpaca-lora (the cleaned version of alpaca) and guanaco. With trained embed and head, the model perform better at Chinese and Japanese then original LLaMA, and with instruction based prompt. You can use this model more easily.
Since this model is trained by guanaco dataset, you can also use this as chatbot. just use this format:
### Instruction: User: <Message history> Assistant: <Message history> ### Input: System: <System response for next message, optional> User: <Next message> ### Response:
Tips: I just removed the first line of original prompt to reduce token comsumption, plz consider remove it when you want to use this model
You can try this model with this colab. And the example below is also generated by this colab notebook.

If you want to use the lora model from leh-weight/ , remember to turn off the load_in_8bit, or manually merge it into 7B model!
Instruction: Write a diary. It should be very long Response: Today was an amazing day! I woke up feeling so refreshed and ready to take on the world. I had a delicious breakfast and went for a morning walk around my neighborhood. I felt so connected to nature and it was so peaceful. After that, I went to the park and enjoyed some time with my friends. We went for a picnic and talked about our hopes and dreams for the future. We also shared stories from our past and laughed until we couldn't breathe. After that, I went home and took a long shower to relax. I then went to the gym and did some cardio and strength training. I felt so strong and powerful after that. I went home and cooked a delicious dinner for my family. We all ate together and talked about our days. It was such a great day and I can't wait to do it again soon.
(if you want to get "accurate answer", I will recommend to use some other tool and hook it to the "system")
======================================== History: User: Hello Assistant: Hello! How can I help you? User: Can you explain how Gradient Descent work? Assistant: Sure, Gradient Descent is a type of optimization algorithm used to find the global minimum of a function. It works by taking small steps in the direction of steepest descent and adjusting the parameters accordingly until the desired result is achieved. ======================================== Message: User: How about Nesterov Accelerated Gradient? Can you campare them? ======================================== Response: Sure, Nesterov Accelerated Gradient is an improved version of Gradient Descent. It uses a combination of linear search and gradient descent algorithms to achieve faster and more accurate results. The main difference between the two algorithms is that Nesterov Accelerated Gradient uses a linear search approach to quickly find the global minimum, while Gradient Descent uses a iterative approach.

First, I think it is obvious that when a LLM isn't good at some language and you want to ft for it. You should train the embed and head part.
But the question is: "Why not just native finetune?"
If you have searched for some alpaca model or training thing, you may notice that lot of them has 1 problem: "memorize".
The loss will drop at the begin of every epoch, just like some kind of "overfit".
And in my opinion, this is because that the number of params of LLaMA is too large. So it just memorize all the training data.
But if I use lora for attention part(ignore MLP part), the param number is not large enough for "memorizing training data", so it is more unlikely to memorize all the things.
