Precise-Physics Driven Text-to-3D Generation

no code implementations19 Mar 2024 Qingshan Xu, Jiao Liu, Melvin Wong, Caishun Chen, Yew-Soon Ong

However, existing generative methods mostly focus on geometric or visual plausibility while ignoring precise physics perception for the generated 3D shapes.

Prompt Evolution for Generative AI: A Classifier-Guided Approach

no code implementations24 May 2023 Melvin Wong, Yew-Soon Ong, Abhishek Gupta, Kavitesh K. Bali, Caishun Chen

Synthesis of digital artifacts conditioned on user prompts has become an important paradigm facilitating an explosion of use cases with generative AI.

ResLogit: A residual neural network logit model for data-driven choice modelling

no code implementations20 Dec 2019 Melvin Wong, Bilal Farooq

This paper presents a novel deep learning-based travel behaviour choice model. Our proposed Residual Logit (ResLogit) model formulation seamlessly integrates a Deep Neural Network (DNN) architecture into a multinomial logit model.

Information processing constraints in travel behaviour modelling: A generative learning approach

no code implementations16 Jul 2019 Melvin Wong, Bilal Farooq

We propose a data-driven generative model version of rational inattention theory to emulate these behavioural representations.

A bi-partite generative model framework for analyzing and simulating large scale multiple discrete-continuous travel behaviour data

no code implementations18 Jan 2019 Melvin Wong, Bilal Farooq

We systematically describe the proposed machine learning algorithm and develop a process of analyzing travel behaviour data from a generative learning perspective.

Modelling Latent Travel Behaviour Characteristics with Generative Machine Learning

no code implementations15 Sep 2018 Melvin Wong, Bilal Farooq

We apply this framework on a mode choice survey data to identify abstract latent variables and compare the performance with a traditional latent variable model with specific latent preferences -- safety, comfort, and environmental.

Discriminative conditional restricted Boltzmann machine for discrete choice and latent variable modelling

no code implementations1 Jun 2017 Melvin Wong, Bilal Farooq, Guillaume-Alexandre Bilodeau

Our findings show that through non-parametric statistical tests, we can extract useful latent information on the behaviour of latent constructs through machine learning methods and present strong and significant influence on the choice process.

An investigation into machine learning approaches for forecasting spatio-temporal demand in ride-hailing service

no code implementations7 Mar 2017 Ismaïl Saadi, Melvin Wong, Bilal Farooq, Jacques Teller, Mario Cools

In this paper, we present machine learning approaches for characterizing and forecasting the short-term demand for on-demand ride-hailing services.
