🚀 ⭐ GLiClass：用于序列分类的通用轻量级模型
GLiClass 是一个高效的零样本分类器，受 GLiNER 工作的启发而开发。它在分类性能上与交叉编码器相当，但计算效率更高，因为它只需一次前向传播即可完成分类。
该模型可用于 主题分类、情感分析，还能在 RAG 管道中作为重排器使用。模型基于合成数据和可商用的许可数据进行训练，因此可应用于商业场景。其骨干模型为 mdeberta-v3-base，支持多语言理解，非常适合处理不同语言的文本任务。
🚀 快速开始
安装 GLiClass 库
首先，你需要安装 GLiClass 库：
pip install gliclass
pip install -U transformers>=4.48.0
初始化模型和管道
以下是不同语言的使用示例：
英语
from gliclass import GLiClassModel, ZeroShotClassificationPipeline
from transformers import AutoTokenizer
model = GLiClassModel.from_pretrained("knowledgator/gliclass-x-base")
tokenizer = AutoTokenizer.from_pretrained("knowledgator/gliclass-x-base", add_prefix_space=True)
pipeline = ZeroShotClassificationPipeline(model, tokenizer, classification_type='multi-label', device='cuda:0')
text = "One day I will see the world!"
labels = ["travel", "dreams", "sport", "science", "politics"]
results = pipeline(text, labels, threshold=0.5)[0]
for result in results:
print(result["label"], "=>", result["score"])
西班牙语
from gliclass import GLiClassModel, ZeroShotClassificationPipeline
from transformers import AutoTokenizer
model = GLiClassModel.from_pretrained("knowledgator/gliclass-x-base")
tokenizer = AutoTokenizer.from_pretrained("knowledgator/gliclass-x-base", add_prefix_space=True)
pipeline = ZeroShotClassificationPipeline(model, tokenizer, classification_type='multi-label', device='cuda:0')
text = "¡Un día veré el mundo!"
labels = ["viajes", "sueños", "deportes", "ciencia", "política"]
results = pipeline(text, labels, threshold=0.5)[0]
for result in results:
print(result["label"], "=>", result["score"])
