GenKL: An Iterative Framework for Resolving Label Ambiguity and Label Non-conformity in Web Images Via a New Generalized KL Divergence
Xia Huang, Kai Fong Ernest Chong
Web image datasets curated online inherently contain ambiguous in-distribution (ID) instances and out-of-distribution (OOD) instances, which we collectively call non-conforming (NC…
Abstract Visual Reasoning: An Algebraic Approach for Solving Raven's Progressive Matrices
Jingyi Xu, Tushar Vaidya, Yufei Wu +3
We introduce algebraic machine reasoning, a new reasoning framework that is well-suited for abstract reasoning. Effectively, algebraic machine reasoning reduces the difficult proce…
FedCorr: Multi-Stage Federated Learning for Label Noise Correction
Jingyi Xu, Zihan Chen, Tony Q. S. Quek +1
Federated learning (FL) is a privacy-preserving distributed learning paradigm that enables clients to jointly train a global model. In real-world FL implementations, client data co…
Dynamic Attention-based Communication-Efficient Federated Learning
Zihan Chen, Kai Fong Ernest Chong, Tony Q. S. Quek
Federated learning (FL) offers a solution to train a global machine learning model while still maintaining data privacy, without needing access to data stored locally at the client…
Training Classifiers that are Universally Robust to All Label Noise Levels
Jingyi Xu, Tony Q. S. Quek, Kai Fong Ernest Chong
For classification tasks, deep neural networks are prone to overfitting in the presence of label noise. Although existing methods are able to alleviate this problem at low noise le…
A closer look at the approximation capabilities of neural networks
Kai Fong Ernest Chong
The universal approximation theorem, in one of its most general versions, says that if we consider only continuous activation functions , then a standard feedforward neural netw…
Flag complexes and homology
Kai Fong Ernest Chong, Eran Nevo
We prove several relations on the -vectors and Betti numbers of flag complexes. For every flag complex , we show that there exists a balanced complex with the same -vector…
The face numbers of homology spheres
Kai Fong Ernest Chong, Tiong Seng Tay
The -theorem is a momentous result in combinatorics that gives a complete numerical characterization of the face numbers of simplicial convex polytopes. The -conjecture asser…
Hilbert functions of colored quotient rings and a generalization of the Clements-Lindström theorem
Kai Fong Ernest Chong
Given a polynomial ring over a field , and a monomial ideal of , we say the quotient ring is Macaulay-Lex if for every graded i…
An application of liaison theory to the Eisenbud-Green-Harris conjecture
Kai Fong Ernest Chong
In this paper, we apply liaison theory to the Eisenbud-Green-Harris conjecture and prove that the conjecture holds for a certain subclass of homogeneous ideals in the linkage class…
Generalized Macaulay representations and the flag -vectors of generalized colored complexes
Kai Fong Ernest Chong
A colored complex of type is a simplicial complex on a vertex set , together with an ordered partition of , such that…
Network Coded Transmission of Fountain Codes over Cooperative Relay Networks
E. Kurniawan, S. Sun, K. Yen +1
In this paper, a transmission strategy of fountain codes over cooperative relay networks is proposed. When more than one relay nodes are available, we apply network coding to fount…
Fountain Codes with Varying Probability Distributions
Kai Fong Ernest Chong, Ernest Kurniawan, Sumei Sun +1
Fountain codes are rateless erasure-correcting codes, i.e., an essentially infinite stream of encoded packets can be generated from a finite set of data packets. Several fountain c…
