The Surprising Effectiveness of Shared Memory in Looped Transformers

Giovanni Monea, Keshav Ramji, Yousef El-Kurdi +4

Looped Transformers apply the same layers several times per token, adding compute to improve quality without more parameters. Each recursion, however, writes its own key-value cach…

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…

ChartNet: A Million-Scale, High-Quality Multimodal Dataset for Robust Chart Understanding

Jovana Kondic, Pengyuan Li, Dhiraj Joshi +24

Understanding charts requires models to jointly reason over geometric visual patterns, structured numerical data, and natural language -- a capability where current vision-language…

Self-Speculative Decoding for LLM-based ASR with CTC Encoder Drafts

George Saon, Samuel Thomas, Takashi Fukuda +3

We propose self-speculative decoding for speech-aware LLMs by using the CTC encoder as a draft model to accelerate auto-regressive (AR) inference and improve ASR accuracy. Our thre…
