Latent Speech-Text Transformer

Yen-Ju Lu, Yashesh Gaur, Wei Zhou +8

Auto-regressive speech-text models pre-trained on interleaved text tokens and discretized speech tokens demonstrate strong speech understanding and generation, yet remain substanti…

When Worse is Better: Navigating the compression-generation tradeoff in visual tokenization

Vivek Ramanujan, Kushal Tirumala, Armen Aghajanyan +2

Current image generation methods are based on a two-stage training approach. In stage 1, an auto-encoder is trained to compress an image into a latent space; in stage 2, a generati…

Recycling the Web: A Method to Enhance Pre-training Data Quality and Quantity for Language Models

Thao Nguyen, Yang Li, Olga Golovneva +4

Scaling laws predict that the performance of large language models improves with increasing model size and data size. In practice, pre-training has been relying on massive web craw…

Mixture-of-Transformers: A Sparse and Scalable Architecture for Multi-Modal Foundation Models

Weixin Liang, Lili Yu, Liang Luo +8

The development of large language models (LLMs) has expanded to multi-modal systems capable of processing text, images, and speech within a unified framework. Training these models…

Multimodal RewardBench: Holistic Evaluation of Reward Models for Vision Language Models

Michihiro Yasunaga, Luke Zettlemoyer, Marjan Ghazvininejad

Reward models play an essential role in training vision-language models (VLMs) by assessing output quality to enable aligning with human preferences. Despite their importance, the…

Mixture-of-Mamba: Enhancing Multi-Modal State-Space Models with Modality-Aware Sparsity

Weixin Liang, Junhong Shen, Genghan Zhang +3

State Space Models (SSMs) have emerged as efficient alternatives to Transformers for sequential modeling, but their inability to leverage modality-specific features limits their pe…
