Multilingual E5 WB

Fine-tuned version of default multilingual-e5-base for WB DS School and RAG project.

Evaluation Results

As model is used as retriever, goal was to boost its performance at cosine similarity between question and answer. With given dataset of QA pairs model performance on EmbeddingSimilarityEvaluator improved from 0.62 to 0.78.
