+# TinyBERT_L-4_H-312_v2 English Sentence Encoder
+
+This is distilled from the `distilbert-base-nli-stsb-mean-tokens` pre-trained model from [Sentence-Transformers](https://sbert.net/).
+
+The embedding vector is obtained by mean/average pooling of the last layer's hidden states.
+
+## Model Comparison
+
+We compute cosine similarity scores of the embeddings of the sentence pair to get the spearman correlation on the STS benchmark (bigger is better):
