ColBERT-X for English-Russian CLIR using Translate-Distill

CLIR Model Setting

Query language: English
Query length: 32 token max
Document language: Russian
Document length: 180 token max (please use MaxP to aggregate the passage score if needed)

Model Description

Translate-Distill is a training technique that produces state-of-the-art CLIR dense retrieval model through translation and distillation. plaidx-large-rus-tdist-mt5xxl-engeng is trained with KL-Divergence from the mt5xxl MonoT5 reranker inferenced on English MS MARCO training queries and English passages.

Teacher Models:

mt5xxl: unicamp-dl/mt5-13b-mmarco-100k

Training Parameters

learning rate: 5e-6
update steps: 200,000
nway (number of passages per query): 6 (randomly selected from 50)
per device batch size (number of query-passage set): 8
training GPU: 8 NVIDIA V100 with 32 GB memory

Usage

To properly load ColBERT-X models from Huggingface Hub, please use the following version of PLAID-X.

pip install PLAID-X==0.3.1

Following code snippet loads the model through Huggingface API.

from colbert.modeling.checkpoint import Checkpoint
from colbert.infra import ColBERTConfig

Checkpoint('hltcoe/plaidx-large-rus-tdist-mt5xxl-engeng', colbert_config=ColBERTConfig())
