The paper introduces a new method called INSTRUCTOR for computing text embeddings based on task instructions. Unlike previous encoders that are specialized for specific tasks, INSTRUCTOR is a single embedder that can generate tailored text embeddings for different downstream tasks and domains without the need for further training. The authors first annotate instructions for 330 diverse tasks and train INSTRUCTOR using a multitask mixture with a contrastive loss. They evaluate the performance of INSTRUCTOR on 70 embedding evaluation tasks, most of which were unseen during training, including classification, information retrieval, semantic textual similarity, and text generation evaluation. Despite having significantly fewer parameters than the previous best model, INSTRUCTOR achieves state-of-the-art performance with an average improvement of 3.4% on the diverse datasets. The authors also demonstrate that INSTRUCTOR is robust to changes in instructions and that instruction finetuning helps mitigate the challenge of training a single model on diverse datasets. The paper concludes by highlighting the availability of their model code and data for researchers and practitioners to benefit from their embeddings or datasets for their specific tasks of interest.

Introducing INSTRUCTOR: A Single Embedder for Computing Text Embeddings

Text embeddings are a powerful tool used to represent text data in numerical form, allowing it to be used in various downstream tasks such as classification, information retrieval, semantic textual similarity, and text generation. However, existing encoders that generate these embeddings are specialized for specific tasks and require further training when applied to different domains or datasets. To address this limitation, researchers from the University of California Irvine have developed a new method called INSTRUCTOR that can generate tailored text embeddings for different downstream tasks without the need for further training.

Annotating Instructions and Training with Multitask Mixture

The authors first annotated instructions for 330 diverse tasks and trained INSTRUCTOR using a multitask mixture with a contrastive loss. The model was then evaluated on 70 embedding evaluation tasks (most of which were unseen during training) including classification, information retrieval, semantic textual similarity and text generation evaluation. Despite having significantly fewer parameters than the previous best model (which had more than twice as many), INSTRUCTOR achieved state-of-the-art performance with an average improvement of 3.4% on the diverse datasets.

Robustness to Changes in Instructions

The authors also demonstrated that INSTRUCTOR is robust to changes in instructions by finetuning instruction sets specifically designed for each task type tested - showing that instruction finetuning helps mitigate the challenge of training a single model on diverse datasets.

Availability of Model Code & Data

Finally, the paper concludes by highlighting the availability of their model code and data for researchers and practitioners to benefit from their embeddings or datasets for their specific tasks of interest - making it easier than ever before to use tailored text embeddings across multiple domains without needing additional training or resources.

In summary, this research paper introduces an innovative new method called INSTRUCTOR which can generate tailored text embeddings quickly and efficiently across multiple domains without requiring any additional training or resources - achieving state-of-the-art performance while being robust against changes in instructions through instruction finetuning techniques. This makes it easier than ever before to use tailored text embeddings across multiple domains without needing additional time or resources - making it an invaluable tool for both researchers and practitioners alike!
