» ChatGPT and the year AI may have officially passed the Turing test (and what it means to the research community)

Rikky Purbojati, Research Computing, NUS Information Technology, on 17 April 2023

Artificial intelligence (AI) has been a popular topic of discussion for many decades, but with the advent of advanced algorithms and powerful computing systems, it has now become a reality. One of the most significant advancements in AI technology is the development of chatbots and language models like OpenAI’s ChatGPT. These systems have elevated people’s imagination beyond expectation and have the potential to revolutionise the way we interact with technology.

» Getting access to the latest scientific software has never been easier with NUS HPC!

Miguel Dias Costa, Research Computing, NUS Information Technology, on 17 April 2023

A common first reaction of new users to shared computing resources such as HPC clusters is to ask, “why can’t I just use yum/apt/etc. to install the software I need?”
Package managers like yum and apt require administrative access and naturally users of a shared resource cannot be given administrative access as they have in their own laptops and desktops, but that’s not the only reason not to use such package managers.

» Quantum-proof Your Research with Free Quantum Credits

Rikky Purbojati, Research Computing, NUS Information Technology, on 24 May 2022

Quantum computing is undeniably one of the most hyped technologies in recent years. With seemingly frequent advancements and milestone announcements, this field has attracted billions of investments into both established and nascent quantum computing vendors. The penultimate promise of quantum computers is that they will enable the computation of intractable problems that classic computers cannot easily solve.

» Anomaly Detection – A Machine Learning Use Case – Part 2

Kuang Hao, Research Computing, NUS Information Technology, on 17 May 2022

Anomaly detection is widely used in behavioural analysis to determine the types of anomalies occurring in a given data set. In domains such as fraud detection, intrusion detection, fault detection and system health monitoring, anomaly detection helps to avoid system damages and potential financial breaches.

Following up on our last article posted in 2020, we will introduce an additional complex machine learning algorithm in anomaly detection and demonstrate how we can do that on our HPC cluster in this article.
