Self-attention-based Graph-of-Thought for Math Problem Solving

ACL 2025finding

Applying Large Language Models (LLM) to solve math problems is one of the hottest research topics at present. Traditional Chain-of-Thought-based methods typically generate the reasoning path in a chain structure, leading to unnecessary interference caused by non-zero self-attention among weakly rela…

Can LLM Find the Green Circle? Investigation and Human-Guided Tool Manipulation for Compositional Generalization

ICASSP 2024accepted

The meaning of complex phrases in natural language is composed of their individual components. The task of compositional generalization evaluates a model’s ability to understand new combinations of components. Previous studies trained smaller, task-specific models, which exhibited poor generalizatio…

DC-Gaussian: Improving 3D Gaussian Splatting for Reflective Dash Cam Videos

NeurIPS 2024poster

We present DC-Gaussian, a new method for generating novel views from in-vehicle dash cam videos. While neural rendering techniques have made significant strides in driving scenarios, existing methods are primarily designed for videos collected by autonomous vehicles. However, these videos are limite…

Uncertainty Estimation on Sequential Labeling via Uncertainty Transmission

NAACL 2024findings

Sequential labeling is a task predicting labels for each token in a sequence, such as Named Entity Recognition (NER). NER tasks aim to extract entities and predict their labels given a text, which is important in information extraction. Although previous works have shown great progress in improving…

Beyond Layout Embedding: Layout Attention with Gaussian Biases for Structured Document Understanding

EMNLP 2023long findings

Effectively encoding layout information is a central problem in structured document understanding. Most existing methods rely heavily on millions of trainable parameters to learn the layout features of each word from Cartesian coordinates. However, two unresolved questions remain: (1) Is the Cartesi…

Exploring Tradeoffs in Automated School Redistricting: Computational and Ethical Perspectives

AAAI 2023technical

The US public school system is administered by local school districts. Each district comprises a set of schools mapped to attendance zones which are annually assessed to meet enrollment objectives. To support school officials in redrawing attendance boundaries, existing approaches have proven promis…

TART: Improved Few-shot Text Classification Using Task-Adaptive Reference Transformation

ACL 2023long

Meta-learning has emerged as a trending technique to tackle few-shot text classification and achieve state-of-the-art performance. However, the performance of existing approaches heavily depends on the inter-class variance of the support set. As a result, it can perform well on tasks when the semant…

Cross-Domain Few-Shot Semantic Segmentation

ECCV 2022poster

"Few-shot semantic segmentation aims at learning to segment a novel object class with only a few annotated examples. Most existing methods consider a setting where base classes are sampled from the same domain as the novel classes. However, in many applications, collecting sufficient training data f…

Uncertainty-Aware Cross-Lingual Transfer with Pseudo Partial Labels

NAACL 2022findings

Large-scale multilingual pre-trained language models have achieved remarkable performance in zero-shot cross-lingual tasks. A recent study has demonstrated the effectiveness of self-learning-based approach on cross-lingual transfer, where only unlabeled data of target languages are required, without…
