EBBS: An Ensemble with Bi-Level Beam Search for Zero-Shot Machine Translation

AAAI 2025technical

The ability of zero-shot translation emerges when we train a multilingual model with certain translation directions; the model can then directly translate in unseen directions. Alternatively, zero-shot translation can be accomplished by pivoting through a third language (e.g., English). In our work,…

Tree-Averaging Algorithms for Ensemble-Based Unsupervised Discontinuous Constituency Parsing

ACL 2024long

We address unsupervised discontinuous constituency parsing, where we observe a high variance in the performance of the only previous model in the literature. We propose to build an ensemble of different runs of the existing discontinuous parser by averaging the predicted trees, to stabilize and boos…

An Equal-Size Hard EM Algorithm for Diverse Dialogue Generation

ICLR 2023poster

Open-domain dialogue systems aim to interact with humans through natural language texts in an open-ended fashion. Despite the recent success of super large dialogue systems such as ChatGPT, using medium-to-small-sized dialogue systems remains the common practice as they are more lightweight and acce…

f-Divergence Minimization for Sequence-Level Knowledge Distillation

ACL 2023long

Knowledge distillation (KD) is the process of transferring knowledge from a large model to a small one. It has gained increasing attention in the natural language processing community, driven by the demands of compressing ever-growing language models. In this work, we propose an FDISTILL framework,…
