STAIR (STructure Aware Information Retriever): A novel dataset and LLM based retriever for document structure augmentation

Vineet Kumar, Meghanadh Pulivarthi, vishwajeet kumar +3

Retrieval Augmented Generation (RAG) is a key component for generating accurate and hallucination free answers using Large Language Models (LLMs). LLMs are improving at handling lo…

DKL: Decoupled Knowledge Learning for Instruction-Tuned Language Models

Kushagra Bhushan, Meghanadh Pulivarthi, Sai Krishna Reddy Sathi +7

RAG has become the de facto method for incorporating new, corpus-specific knowledge into an instruction following LLM (Instruct LLM). Although RAG-based prompting improves factual…

KItCAT: Knowledge Injection via Input Corruption for Auto-regressive Training

Meghanadh Pulivarthi, Kushagra Bhushan, Vineet Kumar +5

LLMs acquire vast amounts of knowledge during pre-training, but often lack the specialized knowledge needed to answer questions from niche sources such as manuals or technical docu…

SearchWiki: Learning to Build and Navigate Knowledge Wikis for Active Information Seeking

Guransh Singh, Vishwajeet Kumar, Arkadeep Acharya +3

Flat retrieval-augmented generation treats a corpus as a bag of chunks, discarding document hierarchy and cross document structure. We introduce SearchWiki, a harness framework tha…

Spatial Matryoshka Training for Multi-Granularity Visual Document Retrieval

Trishan Singha Roy, Arkadeep Acharya, Vishwajeet Kumar +2

Multi-modal late-interaction retrievers achieve strong retrieval on visually rich documents by representing each page as per patch embeddings and matching at the token level. Howev…

CAMI: Cost-Aware Agent-Guided Multi-Indexing for Semantic Retrieval

Adnan Qidwai, Anand Eswaran, Sonam Mishra +2

RAG ingestion pipelines frequently augment search corpus index with semantic enrichment indices (e.g., synthetic queries or summaries generated from corpus chunks) that are subsequ…

Granite Embedding Multilingual R2 Models

Parul Awasthy, Aashka Trivedi, Yushu Yang +14

We introduce the multilingual Granite Embedding R2 models, a family of encoder-based embedding models for enterprise-scale dense retrieval across 200+ languages. Extending our Engl…

Influence Guided Sampling for Domain Adaptation of Text Retrievers

Meet Doshi, Vishwajeet Kumar, Yulong Li +1

General-purpose open-domain dense retrieval systems are usually trained with a large, eclectic mix of corpora and search tasks. How should these diverse corpora and tasks be sample…

LMK > CLS: Landmark Pooling for Dense Embeddings

Meet Doshi, Aashka Trivedi, Vishwajeet Kumar +5

Representation learning is central to many downstream tasks such as search, clustering, classification, and reranking. State-of-the-art sequence encoders typically collapse a varia…
