Characterising harmful data sources when constructing multi-fidelity surrogate models

no code implementations12 Mar 2024 Nicolau Andrés-Thió, Mario Andrés Muñoz, Kate Smith-Miles

These techniques are highly relevant when assessing the performance of a particular design carries a high cost, as the overall cost can be mitigated via the construction of a model to be queried in lieu of the available high-cost source.

Comprehensive Algorithm Portfolio Evaluation using Item Response Theory

1 code implementation29 Jul 2023 Sevvandi Kandanaarachchi, Kate Smith-Miles

Item Response Theory (IRT) has been proposed within the field of Educational Psychometrics to assess student ability as well as test question difficulty and discrimination power.

Generating Dynamic Kernels via Transformers for Lane Detection

1 code implementation ICCV 2023 Ziye Chen, Yu Liu, Mingming Gong, Bo Du, Guoqi Qian, Kate Smith-Miles

While such methods reduce the reliance on specific knowledge, the kernels computed from the key locations fail to capture the lane line's global structure due to its long and thin structure, leading to inaccurate detection of lane lines with complex topologies.

PyHard: a novel tool for generating hardness embeddings to support data-centric analysis

1 code implementation29 Sep 2021 Pedro Yuri Arbs Paiva, Kate Smith-Miles, Maria Gabriela Valeriano, Ana Carolina Lorena

We show in a COVID prognosis dataset how this analysis supported the identification of pockets of hard observations that challenge ML models and are therefore worth closer inspection, and the delineation of regions of strengths and weaknesses of ML models.

Anomaly Detection in High Dimensional Data

1 code implementation12 Aug 2019 Priyanga Dilini Talagala, Rob J. Hyndman, Kate Smith-Miles

The HDoutliers algorithm is a powerful unsupervised algorithm for detecting anomalies in high-dimensional data, with a strong theoretical foundation.
