Efficient Mixture-of-Experts with Speculative Decoding via Expert Coactivation

Kumari Nishu, Han-Byul Kim, Santosh Chilkunda +13

Mixture-of-Experts (MoE) models are increasingly deployed alongside Speculative Decoding (SD) to accelerate inference, but combining the two is challenging. SD improves the inferen…

The Illusion of Thinking: Understanding the Strengths and Limitations of Reasoning Models via the Lens of Problem Complexity

Parshin Shojaee, Iman Mirzadeh, Keivan Alizadeh +3

Recent generations of language models have introduced Large Reasoning Models (LRMs) that generate detailed thinking processes before providing answers. While these models demonstra…

From Dense to Dynamic: Token-Difficulty Driven MoEfication of Pre-Trained LLMs

Kumari Nishu, Sachin Mehta, Samira Abnar +6

Training large language models (LLMs) for different inference constraints is computationally expensive, limiting control over efficiency-accuracy trade-offs. Moreover, once trained…

SALSA: Soup-based Alignment Learning for Stronger Adaptation in RLHF

Atoosa Chegini, Hamid Kazemi, Iman Mirzadeh +5

In Large Language Model (LLM) development, Reinforcement Learning from Human Feedback (RLHF) is crucial for aligning models with human values and preferences. RLHF traditionally re…

KV Prediction for Improved Time to First Token

Maxwell Horton, Qingqing Cao, Chenfan Sun +4

Inference with transformer-based language models begins with a prompt processing step. In this step, the model generates the first output token and stores the KV cache needed for f…

An Efficient and Streaming Audio Visual Active Speaker Detection System

Arnav Kundu, Yanzi Jin, Mohammad Sekhavat +3

This paper delves into the challenging task of Active Speaker Detection (ASD), where the system needs to determine in real-time whether a person is speaking or not in a series of v…
