Handling Overlapping Asymmetric Datasets -- A Twice Penalized P-Spline Approach

no code implementations17 Nov 2023 Matthew McTeer, Robin Henderson, Quentin M Anstee, Paolo Missier

Common solutions such as missing imputation can often be unwise if the smaller cohort is significantly different in scale to the larger sample, therefore the aim of this research is to develop a new method which can model the smaller cohort against a particular response, whilst considering the larger cohort also.

ConvBoost: Boosting ConvNets for Sensor-based Activity Recognition

1 code implementation22 May 2023 Shuai Shao, Yu Guan, Bing Zhai, Paolo Missier, Thomas Ploetz

Specifically, with the introduction of three conceptual layers--Sampling Layer, Data Augmentation Layer, and Resilient Layer -- we develop three "boosters" -- R-Frame, Mix-up, and C-Drop -- to enrich the per-epoch training data by dense-sampling, synthesizing, and simulating, respectively.

Simple Yet Surprisingly Effective Training Strategies for LSTMs in Sensor-Based Human Activity Recognition

no code implementations23 Dec 2022 Shuai Shao, Yu Guan, Xin Guan, Paolo Missier, Thomas Ploetz

What remains a major challenge though is the sporadic activity recognition (SAR) problem, where activities of interest tend to be non periodic, and occur less frequently when compared with the often large amount of irrelevant background activities.

Technologies for Trustworthy Machine Learning: A Survey in a Socio-Technical Context

no code implementations17 Jul 2020 Ehsan Toreini, Mhairi Aitken, Kovila P. L. Coopamootoo, Karen Elliott, Vladimiro Gonzalez Zelaya, Paolo Missier, Magdalene Ng, Aad van Moorsel

As a consequence, we survey in this paper the main technologies with respect to all four of the FEAS properties, for data-centric as well as model-centric stages of the machine learning system life cycle.

Building Rule Hierarchies for Efficient Logical Rule Learning from Knowledge Graphs

1 code implementation29 Jun 2020 Yulong Gu, Yu Guan, Paolo Missier

Many systems have been developed in recent years to mine logical rules from large-scale Knowledge Graphs (KGs), on the grounds that representing regularities as rules enables both the interpretable inference of new facts, and the explanation of known facts.

A customisable pipeline for continuously harvesting socially-minded Twitter users

no code implementations17 Mar 2019 Flavio Primo, Paolo Missier, Alexander Romanovsky, Mickael Figueredo, Nelio Cacho

On social media platforms and Twitter in particular, specific classes of users such as influencers have been given satisfactory operational definitions in terms of network and content metrics.

Recruiting from the network: discovering Twitter users who can help combat Zika epidemics

no code implementations11 Mar 2017 Paolo Missier, Callum McClean, Jonathan Carlton, Diego Cedrim, Leonardo Silva, Alessandro Garcia, Alexandre Plastino, Alexander Romanovsky

Tropical diseases like \textit{Chikungunya} and \textit{Zika} have come to prominence in recent years as the cause of serious, long-lasting, population-wide health problems.
