An Order-Complexity Aesthetic Assessment Model for Aesthetic-aware Music Recommendation

no code implementations13 Feb 2024 Xin Jin, Wu Zhou, Jingyu Wang, Duo Xu, Yongsen Zheng

In order to improve the quality of AI music generation and further guide computer music production, synthesis, recommendation and other tasks, we use Birkhoff's aesthetic measure to design a aesthetic model, objectively measuring the aesthetic beauty of music, and form a recommendation list according to the aesthetic feeling of music.

An Order-Complexity Model for Aesthetic Quality Assessment of Homophony Music Performance

no code implementations23 Apr 2023 Xin Jin, Wu Zhou, Jinyu Wang, Duo Xu, Yiqing Rong, Jialin Sun

In order to guide the generation task of AI music performance, and to improve the performance effect of human performers, this paper uses Birkhoff's aesthetic measure to propose a method of objective measurement of beauty.

Denoising Diffusion Probabilistic Models to Predict the Density of Molecular Clouds

1 code implementation4 Apr 2023 Duo Xu, Jonathan C. Tan, Chia-Jung Hsu, Ye Zhu

We introduce the state-of-the-art deep learning Denoising Diffusion Probabilistic Model (DDPM) as a method to infer the volume or number density of giant molecular clouds (GMCs) from projected mass surface density maps.

Generalizing LTL Instructions via Future Dependent Options

no code implementations8 Dec 2022 Duo Xu, Faramarz Fekri

In many real-world applications of control system and robotics, linear temporal logic (LTL) is a widely-used task specification language which has a compositional grammar that naturally induces temporally extended behaviours across tasks, including conditionals and alternative realizations.

VulCNN: An Image-inspired Scalable Vulnerability Detection System

1 code implementation International Conference on Software Engineering 2022 Yueming Wu, Deqing Zou, Shihan Dou, Wei Yang, Duo Xu, Hai Jin

Furthermore, we conduct a case study on more than 25 million lines of code and the result indicates that VulCNN has the ability to detect large-scale vulnerability.

On the Steady-State Behavior of Finite-Control-Set MPC with an Application to High-Precision Power Amplifiers

no code implementations31 May 2022 Duo Xu, Sander Damsma, Mircea Lazar

To improve the steady-state behavior of FCS-MPC, in this paper we design a cost function that penalizes the tracking error with respect to a state and input steady-state limit cycle.

Interpretable Model-based Hierarchical Reinforcement Learning using Inductive Logic Programming

no code implementations21 Jun 2021 Duo Xu, Faramarz Fekri

In this work, we propose a new hierarchical framework via symbolic RL, leveraging a symbolic transition model to improve the data-efficiency and introduce the interpretability for learned policy.

Improving Actor-Critic Reinforcement Learning via Hamiltonian Monte Carlo Method

no code implementations22 Mar 2021 Duo Xu, Faramarz Fekri

In this work, inspired by the previous use of Hamiltonian Monte Carlo (HMC) in VI, we propose to integrate the policy network of actor-critic RL with HMC, which is termed as {\it Hamiltonian Policy}.

Deep Reinforcement Learning with Implicit Human Feedback

Building atop the baseline, we then make the following novel contributions in our work: (i) We argue that the definition of error-potentials is generalizable across different environments; specifically we show that error-potentials of an observer can be learned for a specific game, and the definition used as-is for another game without requiring re-learning of the error-potentials.
