Alternative Strategies in Learning Nonlinear Soft Margin Support Vector Machines

Informatica Economica, 2014
The aims of the paper are multifold, to propose a new method to determine a suitable value of the bias corresponding to the soft margin SVM classifier and to experimentally evaluate the quality of the found value against one of the standard expression of the bias computed in terms of the support vectors.

A Machine Learning Framework for Oncological Margin Detection

, 2021
Cancer is the cause of one in four deaths in North America. A common phase of early-stage oncological treatment is the surgical resection of cancerous tissue. The presence of cancer cells on the resection margin, referred to as positive margin, is correlated with the recurrence of cancer and demands re-operation.

Towards machine learning-based quantitative hyperspectral image guidance for brain tumor resection [PDF]

Communications Medicine, 2023
Complete resection of malignant gliomas is hampered by the difficulty in distinguishing tumor cells at the infiltration zone. Fluorescence guidance with 5-ALA assists in reaching this goal.

Generative machine learning methods for multivariate ensemble post-processing [PDF]

Annals of Applied Statistics, 2022
Ensemble weather forecasts based on multiple runs of numerical weather prediction models typically show systematic errors and require post-processing to obtain reliable forecasts. Accurately modeling multivariate dependencies is crucial in many practical

Improving Adversarial Robustness of CNNs via Maximum Margin

Applied Sciences, 2022
In recent years, adversarial examples have aroused widespread research interest and raised concerns about the safety of CNNs. We study adversarial machine learning inspired by a support vector machine (SVM), where the decision boundary with maximum ...
