Data-Efficient Contrastive Language-Image Pretraining: Prioritizing Data Quality over Quantity

1 code implementation18 Mar 2024 Siddharth Joshi, Arnav Jain, Ali Payani, Baharan Mirzasoleiman

We show that subsets that closely preserve the cross-covariance of the images and captions of the full data provably achieve a superior generalization performance.

Prompt Mining for Language-based Human Mobility Forecasting

no code implementations6 Mar 2024 Hao Xue, Tianye Tang, Ali Payani, Flora D. Salim

Specifically, the framework includes a prompt generation stage based on the information entropy of prompts and a prompt refinement stage to integrate mechanisms such as the chain of thought.

When is Tree Search Useful for LLM Planning? It Depends on the Discriminator

1 code implementation16 Feb 2024 Ziru Chen, Michael White, Raymond Mooney, Ali Payani, Yu Su, Huan Sun

In this paper, we examine how large language models (LLMs) solve multi-step problems under a language agent framework with three components: a generator, a discriminator, and a planning method.

Large Language Models Can Learn Temporal Reasoning

1 code implementation12 Jan 2024 Siheng Xiong, Ali Payani, Ramana Kompella, Faramarz Fekri

Instead of reasoning over the original context, we adopt a latent representation, temporal graph (TG) that facilitates the TR learning.

TEILP: Time Prediction over Knowledge Graphs via Logical Reasoning

1 code implementation25 Dec 2023 Siheng Xiong, Yuan Yang, Ali Payani, James C Kerce, Faramarz Fekri

We first convert TKGs into a temporal event knowledge graph (TEKG) which has a more explicit representation of time in term of nodes of the graph.

Investigating the Impact of Weight Sharing Decisions on Knowledge Transfer in Continual Learning

no code implementations16 Nov 2023 Josh Andle, Ali Payani, Salimeh Yasaei-Sekeh

Through this lens we demonstrate how task complexity and similarity influence the optimal weight sharing decisions, giving insights into the relationships between tasks and helping inform decision making in similar CL methods.

Few-shot Adaption to Distribution Shifts By Mixing Source and Target Embeddings

no code implementations23 May 2023 Yihao Xue, Ali Payani, Yu Yang, Baharan Mirzasoleiman

Pretrained machine learning models need to be adapted to distribution shifts when deployed in new target environments.

Text-to-SQL Error Correction with Language Models of Code

1 code implementation22 May 2023 Ziru Chen, Shijie Chen, Michael White, Raymond Mooney, Ali Payani, Jayanth Srinivasa, Yu Su, Huan Sun

Thus, we propose a novel representation for SQL queries and their edits that adheres more closely to the pre-training corpora of language models of code.

Mitigating Group Bias in Federated Learning: Beyond Local Fairness

no code implementations17 May 2023 Ganghua Wang, Ali Payani, Myungjin Lee, Ramana Kompella

While many mitigation strategies have been proposed in centralized learning, many of these methods are not directly applicable in federated learning, where data is privately stored on multiple clients.
