# ⭐ 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 uses a layer-wise selection of features that enables a better understanding of different levels of language.
|
27 |
+
|
28 |
+
### How to use:
|
29 |
+
First of all, you need to install GLiClass library:
|
30 |
+
```bash
|
31 |
+
pip install gliclass
|
32 |
+
```
|
33 |
+
|
34 |
+
Than you need to initialize a model and a pipeline:
|
35 |
+
```python
|
36 |
+
from gliclass import GLiClassModel, ZeroShotClassificationPipeline
|
37 |
+
from transformers import AutoTokenizer
|
38 |
+
|
39 |
+
model = GLiClassModel.from_pretrained("knowledgator/gliclass-small-v1.0-lw")
|
40 |
+
tokenizer = AutoTokenizer.from_pretrained("knowledgator/gliclass-small-v1.0-lw")
|
41 |
+
|
42 |
+
pipeline = ZeroShotClassificationPipeline(model, tokenizer, classification_type='multi-label', device='cuda:0')
|
43 |
+
|
44 |
+
text = "One day I will see the world!"
|
45 |
+
labels = ["travel", "dreams", "sport", "science", "politics"]
|
46 |
+
results = pipeline(text, labels, threshold=0.5)[0] #because we have one text
|
47 |
+
|
48 |
+
for result in results:
|
49 |
+
print(result["label"], "=>", result["score"])
|
50 |
+
```
|
51 |
+
|
52 |
+
### Benchmarks:
|
53 |
+
Below, you can see the F1 score on several text classification datasets. All tested models were not fine-tuned on those datasets and were tested in a zero-shot setting.
