An integrated approach for identifying wrongly labelled samples when performing classification in microarray data. [PDF]

PLoS ONE, 2012
Using hybrid approach for gene selection and classification is common as results obtained are generally better than performing the two tasks independently.

Characterization of the effects of outliers on ComBat harmonization for removing inter-site data heterogeneity in multisite neuroimaging studies

Frontiers in Neuroscience, 2023
Data harmonization is a key step widely used in multisite neuroimaging studies to remove inter-site heterogeneity of data distribution. However, data harmonization may even introduce additional inter-site differences in neuroimaging data if outliers are ...

Outlier Removal in 2D Leap Frog Algorithm [PDF]

, 2012
In this paper a 2D Leap Frog Algorithm is applied to solve the so-called noisy Photometric Stereo problem. In 3-source Photometric Stereo (noiseless or noisy) an ideal unknown Lambertian surface is illuminated from distant light-source directions (their directions are assumed to be linearly independent).
