Abstract

The COVID-19 health crisis has seen an increase in the use of digital work platforms from videoconferencing systems to MOOC-type educational platforms and crowdsourcing and freelancing marketplaces. These levers for sharing knowledge and learning constitute the premises of the future of work. Educational technologies coupled with AI hold the promise of helping learners and teachers. However, they are still limited in terms of social interactions, user experience and learning opportunities as they must address a tension between learner-centered and platform-centered goals. Professor Amer-Yahia will describe research at the intersection of data-informed recommendations and education theory and conclude with ethical considerations in building educational platforms.

Abstract

Ten years into the revival of deep networks and artificial intelligence, we propose a theoretical framework that sheds light on understanding deep networks within a bigger picture of intelligence in general. We introduce two fundamental principles, Parsimony and Self-consistency, that address two fundamental questions regarding Intelligence: what to learn and how to learn, respectively. We argue that these two principles can be realized in entirely measurable and computable ways for an important family of structures and models, known as a linear discriminative representation (LDR). The two principles naturally lead to an effective and efficient computational framework, known as a compressive closed-loop transcription, that unifies and explains the evolution of modern deep networks and modern practices of artificial intelligence. Within this framework, we will see how fundamental ideas in information theory, control theory, game theory, sparse coding, and optimization are closely integrated in such a closed-loop system, all as necessary ingredients to learn autonomously and correctly. We demonstrate the power of this framework for learning discriminative, generative, and autoencoding models for large-scale real-world visual data, with entirely white-box deep networks, under all settings (supervised, incremental, and unsupervised). We believe that these two principles are the cornerstones for the emergence of intelligence, artificial or natural, and the compressive closed-loop transcription is a universal learning engine that serves as the basic learning units for all autonomous intelligent systems, including the brain.

HKU-IDS Scholar Seminar Series #2: Huge Language Models: Why They Matter, How They Work, And When They Fail

HKU Musketeers Foundation Institute of Data Science (HKU-IDS) proudly presents the second event under the “HKU-IDS Scholar Seminar Series” which will run through the year of 2022-23.  The seminar series features the HKU-IDS new recruits under HKU-100 Professoriate Recruitment Campaign forming the backbone for the Institute’s cross-disciplinary collaboration. These young talents are co-hosted by IDS and different Departments including Computer Science, Electrical and Electronic Engineering, Architecture, Pharmacy and Pharmacology, Industrial and Manufacturing Systems Engineering and Mathematics.

Title: Huge Language Models: Why They Matter, How They Work, And When They Fail
Speaker: Dr. Tao Yu, the HKU Musketeers Foundation Institute of Data Science and Department of Computer Science, HKU
Moderator: Professor Reynold Cheng, Associate Director of the HKU Musketeers Foundation Institute of Data Science; Professor of Department of Computer Science, HKU
Date: November 17, 2022
Time: 4:00 – 5:00pm

Seminar recording:

Abstract

Recently, we have seen dramatic advances in natural language processing (NLP) driven by huge pre-trained language models such as GPT-3 and DALLE-2. Instead of building many small task-specific models, there is a movement to create and use these more all-purpose huge language models for many NLP applications. The most intriguing finding is that these models employ a new learning paradigm: in-context learning, where they learn to do a downstream task simply by conditioning on a prompt consisting of a few input-output examples without any parameter updates. In this seminar, the speaker will provide a short overview of these language models, discuss their recent progress, why they matter, how they work, and when they fail.

The New IDS Premises Welcomes the Three Musketeers – A Moment for Delight and Progress

The New IDS Premises Welcomes the Three Musketeers - A Moment for Delight and Progress!

Official Launch of the IDS Office (30 September 2022)

The new office premises of the HKU Musketeers Foundation Institute of Data Science at Graduate House, received its first batch of guests – our benefactors from the Musketeers Education and Culture Charitable Foundation, Mr Stanley Chu, Dr Lawrence Fung, and Mr Leong Ka-chai, on September 30, 2022.

Furnished with a modern taste for a research space and equipped with a wealth of advanced audio-visual facilities, the three Musketeers toured in delight at the newly renovated IDS office, with the company of Professor Max Shen, Director of the IDS, Vice-President and Pro-Vice-Chancellor (Research), IDS scholars and Steering Committee members. The eventful day was kick-started with Professor Shen’s sharing of the accomplishment of the Institute since its dedication ceremony on January 5, 2021. With the support of the University management and stakeholders, IDS has gone far and continued to grow stronger and bigger. Young researchers recruited under the Data Science Cluster in the HKU-100 Recruitment Campaign, who were also present that day, impressed the three Musketeers with their aspirations of building a world-class data science research profile for IDS at the meeting that day.

Virtual Tour at the IDS Office Now!

Dr Lawrence Fung (right), Professor Max Shen, Director of the IDS (second to the right), Mr Leong Ka-chai and Mr Stanley Chu (second and third to the left), and Professor Reynold Cheng, Associate Director of the IDS (left), officiated the launch of the IDS premises in a delightful manner.

As Professor Shen has stated, the IDS positions itself to be a place for “facilitating cross-disciplinary research” which can then help make HKU one of the most diverse and outstanding hubs for having different people collaborate together. It echoes the well wishes Dr Lawrence Fung has expressed to us at the event, that the three Musketeers “always hope HKU to be the best, and IDS to be the best” as a research institute. The meeting concluded with the three Musketeers leaving us a food for thought, to which the work of IDS shall gear, that artificial intelligence, being as indispensable as it is in aiding decision-making, will not only become “Explainable AI”, but also “Applicable AI” to the greater crowds.
