Introducing GTE: A General-Purpose Text Embedding Model with Multi-Stage Contrastive Learning

In recent years, natural language processing (NLP) has become a powerful tool for various applications. To make NLP more effective, researchers have developed text embedding models that capture the semantic meaning of words and sentences in a vector representation. However, existing text embedding models are limited in their ability to handle diverse tasks such as code retrieval and question answering. In this paper, we introduce GTE, a general-purpose text embedding model that is trained using multi-stage contrastive learning. By significantly increasing the amount of training data during both unsupervised pre-training and supervised fine-tuning stages, we achieve substantial performance improvements over existing embedding models.

Background on Text Embedding Models

Text embedding models are used to represent words or phrases as numerical vectors in order to capture their semantic meaning. These vectors can then be used for various tasks such as document classification or sentiment analysis. Existing text embedding models include Word2Vec and GloVe which use shallow neural networks to learn word representations from large corpora of text data. More recently, OpenAI's black box API has been released which uses deep learning techniques to generate high quality word vectors from large amounts of unlabeled data.

GTE: General-Purpose Text Embedding Model

The authors propose GTE (General Text Embedding), a general purpose text embedding model that is trained using multi-stage contrastive learning over diverse datasets from multiple sources including web documents, books, news articles etc.. The goal is to unify various NLP tasks into a single format by training a unified text embedding model through contrastive learning over these datasets. Notably even with relatively modest parameter count of 110M , GTE$_\text{base}$ outperforms OpenAI's blackbox API and even surpasses larger text embeddings by 10 times on the massive benchmark dataset . Moreover without additional fine tuning on each programming language individually , it outperforms previous best code retrievers of similar size by treating code as plain texts . This highlights the capability of the model in handling code related tasks effectively .

Multi Stage Contrastive Learning

The key factor behind these impressive results is due to effective utilization of multi stage contrastive learning . During pre training stage , two different views ( e1 & e2 ) are generated for each sentence pair using an encoder network . Then during fine tuning stage , two different views ( f1 & f2 ) are generated again but this time they are conditioned on task specific labels/features like sentiment score or programming language type etc.. Finally during inference stage , only one view ( g ) is used for prediction based on task specific features . This approach allows us to leverage both labeled and unlabeled data efficiently while also allowing us to adapt quickly when new task types arise .

Conclusion

In conclusion , this paper presents GTE as an advanced general purpose text embedding model that achieves state -of -the art performance by leveraging multi -stage contrastive learning technique . Its ability to handle diverse NLP tasks along with its effectiveness in performing well in code related tasks makes it valuable tool for various applications in natural language processing and programming domain
