Learning Symbolic Expressions via Gumbel-Max Equation Learner Networks
Gang Chen
Most of the neural networks (NNs) learned via state-of-the-art machine learning techniques are black-box models. For a widespread success of machine learning in science and enginee…
Merging Deterministic Policy Gradient Estimations with Varied Bias-Variance Tradeoff for Effective Deep Reinforcement Learning
Gang Chen
Deep reinforcement learning (DRL) on Markov decision processes (MDPs) with continuous action spaces is often approached by directly training parametric policies along the direction…
Memetic EDA-Based Approaches to Comprehensive Quality-Aware Automated Semantic Web Service Composition
Chen Wang, Hui Ma, Gang Chen +1
Comprehensive quality-aware automated semantic web service composition is an NP-hard problem, where service composition workflows are unknown, and comprehensive quality, i.e., Qual…
Evolutionary Multitasking for Semantic Web Service Composition
Chen Wang, Hui Ma, Gang Chen +1
Web services are basic functions of a software system to support the concept of service-oriented architecture. They are often composed together to provide added values, known as we…
Off-Policy Actor-Critic in an Ensemble: Achieving Maximum General Entropy and Effective Environment Exploration in Deep Reinforcement Learning
Gang Chen, Yiming Peng
We propose a new policy iteration theory as an important extension of soft policy iteration and Soft Actor-Critic (SAC), one of the most efficient model free algorithms for deep re…
Composing Distributed Data-intensive Web Services Using a Flexible Memetic Algorithm
Soheila Sadeghiram, Hui Ma, Gang Chen
Web Service Composition (WSC) is a particularly promising application of Web services, where multiple individual services with specific functionalities are composed to accomplish a…
Distance-Guided GA-Based Approach to Distributed Data-Intensive Web Service Composition
Soheila Sadeghiram, Hui MA, Gang Chen
Distributed computing which uses Web services as fundamental elements, enables high-speed development of software applications through composing many interoperating, distributed, r…
Effective Exploration for Deep Reinforcement Learning via Bootstrapped Q-Ensembles under Tsallis Entropy Regularization
Gang Chen, Yiming Peng, Mengjie Zhang
Recently deep reinforcement learning (DRL) has achieved outstanding success on solving many difficult and large-scale RL problems. However the high sample cost required for effecti…
An Adaptive Clipping Approach for Proximal Policy Optimization
Gang Chen, Yiming Peng, Mengjie Zhang
Very recently proximal policy optimization (PPO) algorithms have been proposed as first-order optimization methods for effective reinforcement learning. While PPO is inspired by th…
