### 模型 llava-Qwen2-7B-Instruct-Chinese-CLIP 增强中文文字识别能力和表情包内涵识别能力，达到gpt4o、claude-3.5-sonnet的识别水平！
1. 模型结构：</br>
llava-Qwen2-7B-Instruct-Chinese-CLIP = Qwen/Qwen2-7B-Instruct + multi_modal_projector + OFA-Sys/chinese-clip-vit-large-patch14-336px</br>

2. 微调模块
- vision_tower和language_model的q_proj, k_proj, v_proj, o_proj, gate_proj, up_proj, down_proj模块进行lora训练</br>
- mmp层全量训练</br>

3. 微调参数
- lora_r=32,lora_alpha=64,num_train_epochs=5,per_device_train_batch_size=1,gradient_accumulation_steps=8,high_lr=1e-3,low_lr=2e-5,model_max_length=2048.</br>
- 设备：8*A800</br>
- 训练时长：5小时12分钟

5. 数据集</br>
使用gemini-1.5-pro, gemini-1.5-flash, yi-vision, gpt4o,claude-3.5-sonnet模型描述emo-visual-data和ChineseBQB数据集。</br>
文本描述信息通过[text-description-of-the-meme](https://huggingface.co/datasets/REILX/text-description-of-the-meme) 下载</br>
图像可通过[emo-visual-data](https://github.com/LLM-Red-Team/emo-visual-data), [ChineseBQB](https://github.com/zhaoolee/ChineseBQB)下载</br>
图片数据总量1.8G，约10835张中文表情包图片。文字总量42Mb，约24332个图像文本对描述信息。

6. 效果展示</br>
以下测试结果显示模型能识别图像中的文字信息，且能正确识别表情包想要表达的内涵。对比REILX/llava-1.5-7b-hf-meme-lora模型中也测试了原始llava-1.5-7b-hf模型的输出，模型无法正确识别图像中的文本信息。</br>
