What is mmlw-retrieval-roberta-large?
MMLW-retrieval-roberta-large is a specialized neural text encoder designed specifically for Polish language information retrieval tasks. The model transforms both queries and passages into 1024-dimensional vectors, enabling efficient semantic search capabilities. It represents a significant advancement in Polish language processing, achieved through a sophisticated two-step training procedure.
Implementation Details
The model's development follows a carefully crafted two-phase approach: Initial training using multilingual knowledge distillation on 60 million Polish-English text pairs, with English FlagEmbeddings (BGE) serving as teacher models, followed by fine-tuning on Polish MS MARCO data using contrastive loss. The training process utilized substantial computational resources, including a cluster of 12 A100 GPUs, with large batch sizes of 288 for the large model variant.
