+Distilbert encoder models trained on Amazon product-to-product recommendation dataset (LF-AmazonTitles-131K) using [DEXML](https://github.com/nilesh2797/DEXML) ([Dual Encoder for eXtreme Multi-Label classification, ICLR'24](https://arxiv.org/pdf/2310.10636v2.pdf)) method.
+
+## Inference Usage (Sentence-Transformers)
+With `sentence-transformers` installed you can use this model as following:
+```python
+from sentence_transformers import SentenceTransformer
+sentences = ["This is an example sentence", "Each sentence is converted"]
+model = SentenceTransformer('quicktensor/dexml_lf-amazontitles-131k')
+embeddings = model.encode(sentences)
+print(embeddings)
+```
+
+## Usage (HuggingFace Transformers)
+With huggingface transformers you only need to be a bit careful with how you pool the transformer output to get the embedding, you can use this model as following;
+```python
+from transformers import AutoTokenizer, AutoModel
+import torch
+import torch.nn.functional as F
+
+pooler = lambda x: F.normalize(x[:, 0, :], dim=-1) # Choose CLS token and normalize
+
+sentences = ["This is an example sentence", "Each sentence is converted"]
+tokenizer = AutoTokenizer.from_pretrained('quicktensor/dexml_lf-amazontitles-131k')
+model = AutoModel.from_pretrained('quicktensor/dexml_lf-amazontitles-131k')
+
+encoded_input = tokenizer(sentences, padding=True, truncation=True, return_tensors='pt')
+with torch.no_grad():
+    embeddings = pooler(model(**encoded_input))
+
+print(embeddings)
+```
