Parameter-Efficient Transfer Learning for NLP (Foundational PEFT Adapters)

Co-authored the landmark ICML 2019 paper introducing lightweight adapter modules injected into transformer layers, proving models could learn new tasks with less than 3% added parameters.

Model & Execution Context:Bottleneck projection adapters inserted after multi-head attention and feedforward layers.
Scope & Limitations

Serial adapter bottlenecks add minor inference latency compared to re-parameterization techniques like LoRA.

Exploring the Limits of Transfer Learning with a Unified Text-to-Text Transformer (T5)

First author of the seminal T5 paper establishing the unified text-to-text paradigm across all NLP tasks, introducing the C4 (Colossal Clean Crawled Corpus) dataset with over 25,000 academic citations.

Model & Execution Context:Encoder-decoder transformer architecture up to 11B parameters trained on C4 web corpus.
Scope & Limitations

Encoder-decoder architecture has higher KV-cache memory requirements during generation than pure autoregressive decoders.
