CRUXEval-X: A Benchmark for Multilingual Code Reasoning, Understanding and Execution

no code implementations23 Aug 2024 Ruiyang Xu, Jialun Cao, Yaojie Lu, Hongyu Lin, Xianpei Han, Ben He, Shing-Chi Cheung, Le Sun

However, there is an unignorable programming language bias in existing code benchmarks -- over 95% code generation benchmarks are dominated by Python, leaving the LLMs' capabilities in other programming languages such as Java and C/C++ unknown.

Optimizing Long-term Value for Auction-Based Recommender Systems via On-Policy Reinforcement Learning

no code implementations23 May 2023 Ruiyang Xu, Jalaj Bhandari, Dmytro Korenkevych, Fan Liu, Yuchen He, Alex Nikulkov, Zheqing Zhu

Auction-based recommender systems are prevalent in online advertising platforms, but they are typically optimized to allocate recommendation slots based on immediate expected return metrics, neglecting the downstream effects of recommendations on user behavior.

First-Order Problem Solving through Neural MCTS based Reinforcement Learning

no code implementations11 Jan 2021 Ruiyang Xu, Prashank Kadam, Karl Lieberherr

We propose a general framework, Persephone, to map the FOL description of a combinatorial problem to a semantic game so that it can be solved through a neural MCTS based reinforcement learning algorithm.
