External Knowledge Enhanced 3D Scene Generation from Sketch

ECCV 2024poster

"Generating realistic 3D scenes is challenging due to the complexity of room layouts and object geometries. We propose a sketch based knowledge enhanced diffusion architecture (SEK) for generating customized, diverse, and plausible 3D scenes. SEK conditions the denoising process with a hand-drawn sk…

An Empirical Analysis of Leveraging Knowledge for Low-Resource Task-Oriented Semantic Parsing

ACL 2023findings

Task-oriented semantic parsing has drawn a lot of interest from the NLP community, and especially the voice assistant industry as it enables representing the meaning of user requests with arbitrarily nested semantics, including multiple intents and compound entities. SOTA models are large seq2seq tr…

Measuring and Mitigating Local Instability in Deep Neural Networks

ACL 2023findings

Deep Neural Networks (DNNs) are becoming integral components of real world services relied upon by millions of users. Unfortunately, architects of these systems can find it difficult to ensure reliable performance as irrelevant details like random initialization can unexpectedly change the outputs o…

Sketch and Text Guided Diffusion Model for Colored Point Cloud Generation

ICCV 2023poster

Diffusion probabilistic models have achieved remarkable success in text guided image generation. However, generating 3D shapes is still challenging due to the lack of sufficient data containing 3D models along with their descriptions. Moreover, text based descriptions of 3D shapes are inherently amb…

Industry Scale Semi-Supervised Learning for Natural Language Understanding

NAACL 2021industry

This paper presents a production Semi-Supervised Learning (SSL) pipeline based on the student-teacher framework, which leverages millions of unlabeled examples to improve Natural Language Understanding (NLU) tasks. We investigate two questions related to the use of unlabeled data in production SSL c…

Towards Realistic Single-Task Continuous Learning Research for NER

EMNLP 2021finding

There is an increasing interest in continuous learning (CL), as data privacy is becoming a priority for real-world machine learning applications. Meanwhile, there is still a lack of academic NLP benchmarks that are applicable for realistic CL settings, which is a major challenge for the advancement…
