Trustworthy AI Centre NTU (TAICeN)
Principal Investigator: Xie Xiaofei (SMU PI)
Centre for Research on Intelligent Software Engineering (RISE)
Funding Source: Cyber Security Agency of Singapore
Project Synopsis: 

The TAICeN project is focused on developing AI-based solutions for cybersecurity tasks, with two primary research areas: AI for Cybersecurity and Trustworthy AI. Part 1, AI for Cybersecurity, investigates advanced AI technologies for defending against cyber threats such as malware detection, intrusion detection on government cloud systems, crypto attribution, and insider attack attribution. Part 2, Trustworthy AI, ensures the security, robustness, and explainability of the AI-based solutions developed in Part 1. Part 1 will be primarily conducted by NTU, NUS, and BGU, in collaboration with local government agencies. Part 2, led by SMU, explores three key research topics: AI Security, Robustness, and Explanation. AI Security focuses on techniques to mitigate inference attacks, model extraction attacks, adversarial attacks, and poisoning attacks on the solutions. AI Robustness aims to provide quality assurance for AI systems by offering methods to evaluate, debug, and improve AI systems. AI Explainability enables human comprehension and reasoning of the AI decision-making process, which is crucial when predictions have national or safety-critical implications. By addressing both research challenges, the TAICeN project aims to develop effective and trustworthy AI-based solutions for cybersecurity that can keep pace with cybercriminals, automate threat detection, and defend against attacks. Specifically, Prof. Xie Xiaofei and Prof. Sun Jun will focus on the AI Robustness and AI Explainability work packages together with NTU and the relevant partner institutions to demonstrate their research results together with the relevant translation partners.

TrustedSEERs: Trusted Intelligent Work Bots for Engineering Better Software Faster
Principal Investigator: David Lo
School of Computing and Information Systems
Funding Source: National Research Foundation
Project Synopsis: 

This project will pioneer approaches that realize trusted automation bots that act as concierges and interactive advisors to software engineers to improve their productivity as well as software quality. TrustedSEERs will realize such automation by effectively learning from domain-specific, loosely-linked, multi-modal, multi-source and evolving software artefacts (e.g., source code, version history, bug reports, blogs, documentation, Q&A posts, videos, etc.). These artefacts can come from the organization deploying the automation bots, a group of collaborating yet privacy-aware organizations, and from freely available yet possibly licensed (e.g., GPL v2, GPL v3, MIT, etc.) data contributed by many, including untrusted entities, on the internet. TrustedSEERs will bring about the next generation of Software Analytics (SA) – a rapidly growing research area in the Software Engineering research field that turns data into automation – by establishing two initiatives: First, data-centric SA, through the design and development of methods that can systematically engineer (link, select, transform, synthesize, and label) data needed to learn more effective SA bots from diverse software artefacts, many of which are domain-specific and unique. Second, trustworthy SA, through the design and development of mechanisms that can engender software engineers’ trust in SA bots considering both intrinsic factors (explainability) and extrinsic ones (compliance to privacy and copyright laws and robustness to external attacks). In addition, TrustedSEERs will apply its core technologies to synergistic applications to improve engineer productivity and software security.

Public Cleanliness Satisfaction Survey
Principal Investigator: Paulin Tay Straughan
School of Social Sciences
Funding Source: Ministry of Sustainability and the Environment (MSE)
Project Synopsis: 

(This is additional funding to SMU for the existing research project.) MSE and SMU are collaborating to conduct the Public Cleanliness Satisfaction Survey (PCSS), an annual national household survey that aims to measure and track Singaporeans’ satisfaction and perceptions towards public cleanliness and public hygiene. Findings from the survey will aid in identifying key areas of concern and recommendations which are policy or operational in nature, to improve the public’s levels of satisfaction of public cleanliness, public hygiene and/or public cleaning services.

Unleashing the Power of Pre-trained Models for VisualQA: A Skill-based Framework
Principal Investigator: Jiang Jing
School of Computing and Information Systems
Funding Source: Ministry of Education’s Academic Research Fund Tier 2
Project Synopsis: 

Consumers have widely used conversational AI systems such as Siri, Google Assistant and now ChatGPT. The next generation of conversational AI systems will have visual understanding capabilities to communicate with users through language and visual data. A core technology that enables such multimodal, human-like AI systems is visual question answering and the ability to answer questions based on information found in images and videos. This project focuses on visual question answering and aims to develop new visual question-answering technologies based on large-scale pre-trained vision-language models. Pre-training models developed by tech giants, particularly OpenAI, have made headlines in recent years, e.g., ChatGPT, which can converse with users in human language, and DALL-E 2, which can generate realistic images. This project aims to study how to best utilise large-scale pre-trained vision-language models for visual question answering. The project will systematically analyse these pre-trained models in terms of their capabilities and limitations in visual question answering and design technical solutions to bridge the gap between what pre-trained models can accomplish and what visual question answering systems require. The end of the project will be a new framework for building visual question-answering systems based on existing pre-trained models with minimal additional training.

Food Recognition: Causality-driven Cross-modal Cross-lingual Domain Adaptation
Principal Investigator: Ngo Chong Wah
School of Computing and Information Systems
Funding Source: Ministry of Education’s Academic Research Fund Tier 2
Project Synopsis: 

This project aims to improve the scalability of food recognition – to train classifier(s) that recognise a wide range of dishes regardless of cuisines, the amount and type of training examples. Here, “classifier” can be viewed as a “search engine” that retrieves the recipe of a food image. Training such classifiers requires an excessive number of training examples composed of recipes and images, where each recipe is paired with at least an image as visual reference. Training classifiers using paired or parallel data faces several practical limitations – tens of thousands of recipe-image pairs are required for training; other forms of data that are largely available in the public cannot be leveraged for model training; and additional training data is required when the recipes are written in different natural languages. Through the project, these practical limitations will be addressed from the perspective of transfer learning. The aim is to train a generalised classifier that is more adaptable for recognition, by removing the statistical bias, considering the evolving process, and aligning the semantics of different languages in machine learning.

Executable AI Semantics for AI Framework Analysis
Principal Investigator: Sun Jun
School of Computing and Information Systems
Funding Source: Ministry of Education’s Academic Research Fund Tier 2
Project Synopsis: 

This project aims to provide a solid foundation for analysing AI systems as well as techniques used to facilitate the development of reliable secure AI systems. Central to the research is to develop an executable specification in the form of an abstract logical representation of all components that are used to build artificial intelligence, which subsequentially enables powerful techniques to address three problems commonly encountered in AI systems, namely, how to ensure the quality or correctness of AI libraries, how to systematically locate bugs in neural network programs, and how to fix the bug. In other words, this project aims to define a semantics of AI models, thereby forming a solid fundamental to build AI systems upon.

Text Style Transfer with Pre-Trained Language Models
Principal Investigator: Jiang Jing
School of Computing and Information Systems
Funding Source: DSO National Laboratories
Project Synopsis: 

Text style transfer (TST) is the task of converting a piece of text written in one style (e.g., informal text) into text written in a different style (e.g., formal text). It has applications in many scenarios such as AI-based writing assistance and removal of offensive language in social media posts. Recent years, with the advances of pre-trained large-scale language models such as the Generative Pre-trained Transformer 3 (GPT-3) which is an autoregressive language model that uses deep learning to produce human-like text, solutions to TST are now shifting to fine-tuning-based and prompt-based approaches. In this project, we will study how to effectively utilize pre-trained language models for TST under low-resource settings. We will also design ways to measure whether solutions based on pre-trained language models can disentangle content and style.
