T-NGA: Temporal Network Grafting Algorithm for Learning to Process Spiking Audio Sensor Events

no code implementations7 Feb 2022 Shu Wang, Yuhuang Hu, Shih-Chii Liu

This work proposes a self-supervised method called Temporal Network Grafting Algorithm (T-NGA), which grafts a recurrent network pretrained on spectrogram features so that the network works with the cochlea event features.

Evolved Massive Stars at Low-metallicity IV. Using 1.6 $μ$m "H-bump" to identify red supergiant stars: a case study of NGC 6822

no code implementations21 Jan 2021 Ming Yang, Alceste Z. Bonanos, Biwei Jiang, Man I Lam, Jian Gao, Panagiotis Gavras, Grigoris Maravelias, Shu Wang, Xiao-Dian Chen, Frank Tramper, Yi Ren, Zoi T. Spetsieri

Further separating RSG candidates from the rest of the LSG candidates is done by using semi-empirical criteria on NIR CMDs and resulted in 323 RSG candidates.

Joint Mind Modeling for Explanation Generation in Complex Human-Robot Collaborative Tasks

no code implementations24 Jul 2020 Xiaofeng Gao, Ran Gong, Yizhou Zhao, Shu Wang, Tianmin Shu, Song-Chun Zhu

Thus, in this paper, we propose a novel explainable AI (XAI) framework for achieving human-like communication in human-robot collaborations, where the robot builds a hierarchical mind model of the human user and generates explanations of its own mind as a form of communications based on its online Bayesian inference of the user's mental state.

A Bayesian Finite Mixture Model with Variable Selection for Data with Mixed-type Variables

no code implementations9 May 2019 Shu Wang, Jonathan G. Yabes, Chung-Chou H. Chang

To address these challenges, we propose a Bayesian finite mixture model to simultaneously conduct variable selection, account for biomarker LOD and obtain clustering results.

Hybrid Density- and Partition-based Clustering Algorithm for Data with Mixed-type Variables

no code implementations6 May 2019 Shu Wang, Jonathan G. Yabes, Chung-Chou H. Chang

However, algorithms that can cluster data with mixed variable types (continuous and categorical) remain limited, despite the abundance of data with mixed types particularly in the medical field.

VRKitchen: an Interactive 3D Virtual Environment for Task-oriented Learning

1 code implementation13 Mar 2019 Xiaofeng Gao, Ran Gong, Tianmin Shu, Xu Xie, Shu Wang, Song-Chun Zhu

One of the main challenges of advancing task-oriented learning such as visual task planning and reinforcement learning is the lack of realistic and standardized environments for training and testing AI agents.

An Interval-Based Bayesian Generative Model for Human Complex Activity Recognition

no code implementations4 Jan 2017 Li Liu, Yongzhong Yang, Lakshmi Narasimhan Govindarajan, Shu Wang, Bin Hu, Li Cheng, David S. Rosenblum

We propose in this paper an atomic action-based Bayesian model that constructs Allen's interval relation networks to characterize complex activities with structural varieties in a probabilistic generative way: By introducing latent variables from the Chinese restaurant process, our approach is able to capture all possible styles of a particular complex activity as a unique set of distributions over atomic actions and relations.

A New Framework for Sign Language Recognition based on 3D Handshape Identification and Linguistic Modeling

no code implementations LREC 2014 Mark Dilsizian, Polina Yanovich, Shu Wang, Carol Neidle, Dimitris Metaxas

Current approaches to sign recognition by computer generally have at least some of the following limitations: they rely on laboratory conditions for sign production, are limited to a small vocabulary, rely on 2D modeling (and therefore cannot deal with occlusions and off-plane rotations), and/or achieve limited success.
