Root Cause Explanation of Outliers under Noisy Mechanisms

no code implementations19 Dec 2023 Phuoc Nguyen, Truyen Tran, Sunil Gupta, Thin Nguyen, Svetha Venkatesh

We then represent the functional form of a target outlier leaf as a function of the node and edge noises.

Robust Estimation of Causal Heteroscedastic Noise Models

no code implementations15 Dec 2023 Quang-Duy Tran, Bao Duong, Phuoc Nguyen, Thin Nguyen

One solution to this problem is assuming that cause and effect are generated from a structural causal model, enabling identification of the causal direction after estimating the model in each direction.

Differentiable Bayesian Structure Learning with Acyclicity Assurance

1 code implementation4 Sep 2023 Quang-Duy Tran, Phuoc Nguyen, Bao Duong, Thin Nguyen

Score-based approaches in the structure learning task are thriving because of their scalability.

Memory-Augmented Theory of Mind Network

no code implementations17 Jan 2023 Dung Nguyen, Phuoc Nguyen, Hung Le, Kien Do, Svetha Venkatesh, Truyen Tran

Social reasoning necessitates the capacity of theory of mind (ToM), the ability to contextualise and attribute mental states to others without having access to their internal cognitive structure.

Learning Theory of Mind via Dynamic Traits Attribution

no code implementations17 Apr 2022 Dung Nguyen, Phuoc Nguyen, Hung Le, Kien Do, Svetha Venkatesh, Truyen Tran

Inspired by the observation that humans often infer the character traits of others, then use it to explain behaviour, we propose a new neural ToM architecture that learns to generate a latent trait vector of an actor from the past trajectories.

Learning to Transfer Role Assignment Across Team Sizes

no code implementations17 Apr 2022 Dung Nguyen, Phuoc Nguyen, Svetha Venkatesh, Truyen Tran

In particular, we train a role assignment network for small teams by demonstration and transfer the network to larger teams, which continue to learn through interaction with the environment.

Unsupervised Anomaly Detection on Temporal Multiway Data

no code implementations20 Sep 2020 Duc Nguyen, Phuoc Nguyen, Kien Do, Santu Rana, Sunil Gupta, Truyen Tran

These include the capacity of the compact matrix LSTM to compress noisy data near perfectly, making the strategy of compressing-decompressing data ill-suited for anomaly detection under the noise.

Theory of Mind with Guilt Aversion Facilitates Cooperative Reinforcement Learning

no code implementations16 Sep 2020 Dung Nguyen, Svetha Venkatesh, Phuoc Nguyen, Truyen Tran

In psychological game theory, guilt aversion necessitates modelling of agents that have theory about what other agents think, also known as Theory of Mind (ToM).

Variational Hyper-Encoding Networks

no code implementations18 May 2020 Phuoc Nguyen, Truyen Tran, Sunil Gupta, Santu Rana, Hieu-Chi Dam, Svetha Venkatesh

Given a target distribution, we predict the posterior distribution of the latent code, then use a matrix-network decoder to generate a posterior distribution q(\theta).

Measuring English Readability for Vietnamese Speakers

no code implementations ALTA 2019 Phuoc Nguyen, Alex Uitdenbogerd, ra

This study introduces a first approximation to readability of English text for VL1, with suggestions for further improvements.

Intelligent Device Discovery in the Internet of Things - Enabling the Robot Society

no code implementations22 Dec 2017 James Sunthonlap, Phuoc Nguyen, Zilong Ye

The Internet of Things (IoT) is continuously growing to connect billions of smart devices anywhere and anytime in an Internet-like structure, which enables a variety of applications, services and interactions between human and objects.

Finding Algebraic Structure of Care in Time: A Deep Learning Approach

no code implementations21 Nov 2017 Phuoc Nguyen, Truyen Tran, Svetha Venkatesh

The interaction between diseases and treatments at a visit is modeled as the residual of the diseases minus the treatments.

Deep Learning to Attend to Risk in ICU

no code implementations17 Jul 2017 Phuoc Nguyen, Truyen Tran, Svetha Venkatesh

At the reasoning layer, evidences across time steps are weighted and combined.

Decision Making ICU Mortality +2

Deepr: A Convolutional Net for Medical Records

no code implementations26 Jul 2016 Phuoc Nguyen, Truyen Tran, Nilmini Wickramasinghe, Svetha Venkatesh

On top of the sequence is a convolutional neural net that detects and combines predictive local clinical motifs to stratify the risk.
