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

CLIR Model Setting

• Query language: English
• Query length: 32 token max
• Document language: Persian
• 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-fas-tdist-mt5xxl-engfas is trained with KL-Divergence from the mt5xxl MonoT5 reranker inferenced on English MS MARCO training queries and Persian translated passages.

Teacher Models:

• t53b: castorini/monot5-3b-msmarco-10k
• 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-fas-tdist-mt5xxl-engfas', colbert_config=ColBERTConfig())
