12th Asian Conference on Machine Learning

by Lucy Smith

25 November 2020

Invited talks

There were four invited speakers:
Suriya Gunasekar (Microsoft Research, USA)
Rethinking the role of optimization in learning
This talk presented an overview of recent results towards understanding how we learn large capacity machine learning models. It also explored the role optimization algorithms, like (stochastic) gradient descent, play in learning overparameterized models in the simpler setting of learning linear predictors.

Alice Oh (KAIST, Korea)
Open domain dialogue response generation: models and evaluation metrics
This talk covered the important topic of dialogue response generation, with the open domain perspective, meaning the topics of the dialogues are not pre-specified. A new model (called Variable Hierarchical User-based Conversation Model) is described, which considers the previous dialogues among users, as well as their social network connections.

Lee Wee Sun (National University of Singapore, Singapore)
Neuralizing algorithms
This talk considered approximation algorithms, and described work to augment them with learnable components to allow learning of more powerful approximation algorithms that are then tuned to work on the target problem distribution. This was demonstrated by use of a Factor Graph Neural Network.

Chidchanok Lursinsap (Chulalongkorn University, Thailand)
Fast and accurate neural learning with limited memory size, limited energy supply, and class drift constraints in streaming data environment
This talk discussed a new concept of neural learning, the supporting architecture, and the relevant theoretical foundation to achieve an efficient leaning process with high accuracy under the constraints of memory overflow and controllable polynomial time complexity.

Workshops

Weakly-supervised representation learning
The focus of this workshop was five types of weak supervision: incomplete supervision, inexact supervision, inaccurate supervision, cross-domain supervision and imperfect demonstration.

Machine learning in Thailand
This workshop was designed to survey the state of ML applications and research in Thailand and neighbouring countries in South East Asia.

Papers
