Instructor Base Sentence Embeddings

Description

Instructor👨‍🏫, an instruction-finetuned text embedding model that can generate text embeddings tailored to any task (e.g., classification, retrieval, clustering, text evaluation, etc.) and domains (e.g., science, finance, etc.) by simply providing the task instruction, without any finetuning. Instructor👨‍ achieves sota on 70 diverse embedding tasks.

How to use

instruction = InstructorEmbeddings.pretrained("instructor_base","en") \
            .setInstruction("Instruction here: ") \
            .setInputCols(["documents"]) \
            .setOutputCol("instructor")

        pipeline = Pipeline().setStages([document_assembler, instruction])

    val embeddings = InstructorEmbeddings
      .pretrained("instructor_base","en")
      .setInstruction("Instruction here: ")
      .setInputCols(Array("document"))
      .setOutputCol("instructor")

    val pipeline = new Pipeline().setStages(Array(document, embeddings))
