LayerToFair: An Efficient Post-processing Framework for Layer-aware Fairness Repair of Deep Neural Networks

DNNs are increasingly deployed in high-stakes information systems, where fairness is a critical requirement. Existing post-processing methods can repair unfairness without retraining or accessing original data, but they often treat all layers indiscriminately, resulting in high c...

EquivSage: LLM-assisted Detection of EVM-Inequivalent Code Smells in Multi-chain Reuse Contracts

With the increasing development of Solidity contracts on Ethereum , more developers are reusing them on other compatible blockchains. However, developers may overlook the differences between the designs of the blockchain system, such as the Gas Mechanism and Consensus Protocol ,...
