On Model Evaluation under Non-constant Class Imbalance
Jan Brabec, Tomáš Komárek, Vojtěch Franc +1
Many real-world classification problems are significantly class-imbalanced to detriment of the class of interest. The standard set of proper evaluation metrics is well-known but th…
Time-dependent diffusion in undulating structures: Impact on axon diameter estimation
Jan Brabec, Samo Lasic, Markus Nilsson
Diffusion MRI may enable non-invasive mapping of axonal microstructure. Most approaches infer axon diameters from effects of time-dependent diffusion on the diffusion-weighted MR s…
Tensor-valued diffusion MRI in under 3 minutes: An initial survey of microscopic anisotropy and tissue heterogeneity in intracranial tumors
Markus Nilsson, Filip Szczepankiewicz, Jan Brabec +5
Purpose: To evaluate the feasibility of a 3-minute b-tensor encoding protocol for diffusion MRI-based assessment of the microscopic anisotropy and tissue heterogeneity in a wide ra…
Bad practices in evaluation methodology relevant to class-imbalanced problems
Jan Brabec, Lukas Machlica
For research to go in the right direction, it is essential to be able to compare and quantify performance of different algorithms focused on the same problem. Choosing a suitable e…
