MLP Fusion: Towards Efficient Fine-tuning of Dense and Mixture-of-Experts Language Models

Mengting Ai, Tianxin Wei, Yifan Chen +2

Fine-tuning a pre-trained language model (PLM) emerges as the predominant strategy in many natural language processing applications. However, this process is known to be expensive,…

A Gromov--Wasserstein Geometric View of Spectrum-Preserving Graph Coarsening

Yifan Chen, Rentian Yao, Yun Yang +1

Graph coarsening is a technique for solving large-scale graph problems by working on a smaller version of the original graph, and possibly interpolating the results back to the ori…

Inducer-tuning: Connecting Prefix-tuning and Adapter-tuning

Yifan Chen, Devamanyu Hazarika, Mahdi Namazifar +3

Prefix-tuning, or more generally continuous prompt tuning, has become an essential paradigm of parameter-efficient transfer learning. Using a large pre-trained language model (PLM)…

Empowering parameter-efficient transfer learning by recognizing the kernel structure in self-attention

Yifan Chen, Devamanyu Hazarika, Mahdi Namazifar +3

The massive amount of trainable parameters in the pre-trained language models (PLMs) makes them hard to be deployed to multiple downstream tasks. To address this issue, parameter-e…

Sketching as a Tool for Understanding and Accelerating Self-attention for Long Sequences

Yifan Chen, Qi Zeng, Dilek Hakkani-Tur +3

Transformer-based models are not efficient in processing long sequences due to the quadratic space and time complexity of the self-attention modules. To address this limitation, Li…

Skyformer: Remodel Self-Attention with Gaussian Kernel and Nyström Method

Yifan Chen, Qi Zeng, Heng Ji +1

Transformers are expensive to train due to the quadratic time and space complexity in the self-attention mechanism. On the other hand, although kernel machines suffer from the same…
