Exploring the Limitations of Large Language Models in Compositional Relation Reasoning

no code implementations5 Mar 2024 Jinman Zhao, Xueyan Zhang

We present a comprehensive evaluation of large language models(LLMs)' ability to reason about composition relations through a benchmark encompassing 1, 500 test cases in English, designed to cover six distinct types of composition relations: Positional, Comparative, Personal, Mathematical, Identity, and Other.

Better Context Makes Better Code Language Models: A Case Study on Function Call Argument Completion

no code implementations1 Jun 2023 Hengzhi Pei, Jinman Zhao, Leonard Lausen, Sheng Zha, George Karypis

To better solve this task, we query a program analyzer for information relevant to a given function call, and consider ways to provide the analyzer results to different code completion models during inference and training.

Neural-Augmented Static Analysis of Android Communication

no code implementations11 Sep 2018 Jinman Zhao, Aws Albarghouthi, Vaibhav Rastogi, Somesh Jha, Damien Octeau

We address the problem of discovering communication links between applications in the popular Android mobile operating system, an important problem for security and privacy in Android.

The Effect of Network Width on the Performance of Large-batch Training

no code implementations NeurIPS 2018 Lingjiao Chen, Hongyi Wang, Jinman Zhao, Dimitris Papailiopoulos, Paraschos Koutris

Distributed implementations of mini-batch stochastic gradient descent (SGD) suffer from communication overheads, attributed to the high frequency of gradient updates inherent in small-batch training.
