# ⭐ GLiClass: Generalist and Lightweight Model for Sequence Classification
|
| 19 |
+
|
| 20 |
+
This is an efficient zero-shot classifier inspired by [GLiNER](https://github.com/urchade/GLiNER/tree/main) work. It demonstrates the same performance as a cross-encoder while being more compute-efficient because classification is done at a single forward path.
|
| 21 |
+
|
| 22 |
+
It can be used for `topic classification`, `sentiment analysis` and as a reranker in `RAG` pipelines.
|
| 23 |
+
|
| 24 |
+
The model was trained on synthetic data and can be used in commercial applications.
|
| 25 |
+
|
| 26 |
+
This version of the model utilize the [LLM2Vec](https://github.com/McGill-NLP/llm2vec/tree/main/llm2vec) approach for converting modern decoders to bi-directional encoder. It brings the following benefits:
|
| 27 |
+
* Enhanced performance and generalization capabilities;
|
| 28 |
+
* Support for Flash Attention;
|
| 29 |
+
* Extended context window.

### How to use:
|
| 33 |
+
First of all, you need to install GLiClass library:
|
| 34 |
+
```bash
|
| 35 |
+
pip install gliclass
|
| 36 |
+
```
|
| 37 |
+
|
| 38 |
+
To use this particular Qwen-based model you need different `transformers` package version than llm2vec requires, so install it manually:
|
| 39 |
+
```bash
|
| 40 |
+
pip install transformers==4.44.1
|
| 41 |
+
```
|
| 42 |
+
|
| 43 |
+
Than you need to initialize a model and a pipeline:
|
| 44 |
+
```python
|
| 45 |
+
from gliclass import GLiClassModel, ZeroShotClassificationPipeline
|
| 46 |
+
from transformers import AutoTokenizer
|
| 47 |
+
|
| 48 |
+
model = GLiClassModel.from_pretrained("knowledgator/gliclass-qwen-1.5B-v1.0")
|
| 49 |
+
tokenizer = AutoTokenizer.from_pretrained("knowledgator/gliclass-qwen-1.5B-v1.0")
|
| 50 |
+
|
| 51 |
+
pipeline = ZeroShotClassificationPipeline(model, tokenizer, classification_type='multi-label', device='cuda:0')
|
| 52 |
+
|
| 53 |
+
text = "One day I will see the world!"
|
| 54 |
+
labels = ["travel", "dreams", "sport", "science", "politics"]
|
| 55 |
+
results = pipeline(text, labels, threshold=0.5)[0] #because we have one text
|
| 56 |
+
|
| 57 |
+
for result in results:
|
| 58 |
+
print(result["label"], "=>", result["score"])
|
| 59 |
+
```
|
| 60 |
+
|
| 61 |
+
### Benchmarks:
|
| 62 |
+
While the model is some how comparable to DeBERTa version in zero-shot setting, it demonstrates state-of-the-art performance in few-shot setting.
