Efficient Task Grouping Through Samplewise Optimisation Landscape Analysis

no code implementations5 Dec 2024 Anshul Thakur, Yichen Huang, Soheila Molaei, Yujiang Wang, David A. Clifton

Shared training approaches, such as multi-task learning (MTL) and gradient-based meta-learning, are widely used in various machine learning applications, but they often suffer from negative transfer, leading to performance degradation in specific tasks.

Data Encoding For Healthcare Data Democratisation and Information Leakage Prevention

1 code implementation5 May 2023 Anshul Thakur, Tingting Zhu, Vinayak Abrol, Jacob Armstrong, Yujiang Wang, David A. Clifton

Experimental evaluation highlights that models trained on encoded time-series data effectively uphold the information bottleneck principle and hence, exhibit lesser information leakage from trained models.

COPER: Continuous Patient State Perceiver

1 code implementation5 Aug 2022 Vinod Kumar Chauhan, Anshul Thakur, Odhran O'Donoghue, David A. Clifton

COPER uses Perceiver model and the concept of neural ordinary differential equations (ODEs) to learn the continuous time dynamics of patient state, i. e., continuity of input space and continuity of output space.
