# SLX-v0.1
|
15 |
+
|
16 |
+
**SLX-v0.1** is an advanced model developed by [BRAHMAI Research](https://brahmai.in), specifically designed for mapping sentences and paragraphs into a 384-dimensional dense vector space. This model is ideal for tasks such as clustering, semantic search, and sentence similarity.
|
17 |
+
|
18 |
+
## Usage with Sentence-Transformers
|
19 |
+
|
20 |
+
Using SLX-v0.1 is straightforward with the [Sentence-Transformers](https://www.SBERT.net) library. Follow the instructions below to get started:
|
21 |
+
|
22 |
+
### Installation
|
23 |
+
|
24 |
+
```bash
|
25 |
+
pip install -U sentence-transformers
|
26 |
+
```
|
27 |
+
|
28 |
+
### Example
|
29 |
+
|
30 |
+
```python
|
31 |
+
from sentence_transformers import SentenceTransformer
|
32 |
+
|
33 |
+
sentences = ["This is an example sentence", "Each sentence is converted"]
|
34 |
+
model = SentenceTransformer('brahmairesearch/slx-v0.1')
|
35 |
+
embeddings = model.encode(sentences)
|
36 |
+
|
37 |
+
print(embeddings)
|
38 |
+
```
|
39 |
+
|
40 |
+
## Usage with Hugging Face Transformers
|
41 |
+
|
42 |
+
If you prefer to use Hugging Face Transformers without the Sentence-Transformers library, you can still utilize the SLX-v0.1 model. Below is a guide on how to process input and apply mean pooling to obtain sentence embeddings:
|
43 |
+
|
44 |
+
```python
|
45 |
+
from transformers import AutoTokenizer, AutoModel
|
46 |
+
import torch
|
47 |
+
import torch.nn.functional as F
|
48 |
+
|
49 |
+
# Mean Pooling - Takes attention mask into account for correct averaging
|
50 |
+
def mean_pooling(model_output, attention_mask):
|
51 |
+
token_embeddings = model_output[0] # Token embeddings from the model output
|
52 |
+
input_mask_expanded = attention_mask.unsqueeze(-1).expand(token_embeddings.size()).float()
|
53 |
+
return torch.sum(token_embeddings * input_mask_expanded, 1) / torch.clamp(input_mask_expanded.sum(1), min=1e-9)
|
54 |
+
|
55 |
+
# Sentences for embedding
|
56 |
+
sentences = ['This is an example sentence', 'Each sentence is converted']
|
57 |
+
|
58 |
+
# Load model from Hugging Face Hub
|
59 |
+
tokenizer = AutoTokenizer.from_pretrained('brahmairesearch/slx-v0.1')
|
60 |
+
model = AutoModel.from_pretrained('brahmairesearch/slx-v0.1')
|
61 |
+
|
62 |
+
# Tokenize sentences
|
63 |
+
encoded_input = tokenizer(sentences, padding=True, truncation=True, return_tensors='pt')
|
64 |
+
|
65 |
+
# Compute token embeddings
|
66 |
+
with torch.no_grad():
|
67 |
+
model_output = model(**encoded_input)
|
68 |
+
|
69 |
+
# Perform pooling
|
70 |
+
sentence_embeddings = mean_pooling(model_output, encoded_input['attention_mask'])
|
71 |
+
|
72 |
+
# Normalize embeddings
|
73 |
+
sentence_embeddings = F.normalize(sentence_embeddings, p=2, dim=1)
|
74 |
+
|
75 |
+
print("Sentence embeddings:")
|
76 |
+
print(sentence_embeddings)
|
77 |
+
```
|
78 |
+
|
79 |
+
## Evaluation Results
|
80 |
+
|
81 |
+
For an automated evaluation of SLX-v0.1, please refer to the [Sentence Embeddings Benchmark](https://seb.sbert.net?model_name=brahmairesearch/slx-v0.1).
|
82 |
+
|
83 |
+
## Intended Use Cases
|
84 |
+
|
85 |
+
SLX-v0.1 is designed for encoding sentences and short paragraphs into dense vectors that capture their semantic information. These embeddings can be used for:
|
86 |
+
|
87 |
+
- Information retrieval
|
88 |
+
- Clustering
|
89 |
+
- Sentence similarity tasks
|
90 |
+
|
91 |
+
Please note that input text longer than 256 word pieces will be truncated by default.
|
92 |
+
|
93 |
+
## Training Procedure
|
94 |
+
|
95 |
+
### Pre-training
|
96 |
+
|
97 |
+
SLX-v0.1 is based on the pre-trained model [`nreimers/MiniLM-L6-H384-uncased`](https://huggingface.co/nreimers/MiniLM-L6-H384-uncased). For more information on the pre-training process, please refer to the original model card.
|
98 |
+
|
99 |
+
### Fine-tuning
|
100 |
+
|
101 |
+
The model was fine-tuned using a contrastive learning objective. Cosine similarity is computed between all possible sentence pairs within a batch, and cross-entropy loss is applied using the true pairs.
|
102 |
+
|
103 |
+
Following fine-tuning, the model underwent transfer learning using the [`dunzhang/stella_en_400M_v5`](https://huggingface.co/dunzhang/stella_en_400M_v5) model with an internally curated dataset, optimizing it for English language tasks.
