Learn Continually, Generalize Rapidly: Lifelong Knowledge Accumulation for Few-shot Learning
This repo is for Findings at EMNLP 2021 paper: Learn Continually, Generalize Rapidly: Lifelong Knowledge Accumulation for Few-shot Learning. Code clean-up is still in progress.
Data
Please extract the downloaded data and place it under PROJECT_DIR/datasets. Our training data stream and few-shot datasets are curated from https://github.com/iesl/leopard and https://github.com/INK-USC/CrossFit.
The directory structure is
PROJECT_DIR/datasets/crossfit_data/data/ + 55 classification tasks from the link above, e.g. PROJECT_DIR/datasets/crossfit_data/data/anli
PROJECT_DIR/datasets/leopard/ + 17 tasks from the link above, e.g. PROJECT_DIR/datasets/leopard/airline
Environment
Our code uses PyTorch 1.7.1. To allow fp16 training, you should also install apex.
