Prototypes Sampling Mechanism for Class Incremental Learning

open access: yesIEEE Access, 2023
Incremental learning aims to alleviate the catastrophic forgetting problem of deep neural networks during learning sequential data stream. This problem is even more challenging when old data is unavailable, since learning system can only be trained under

Self Reinforcing Multi-Class Transformer for Kidney Glomerular Basement Membrane Segmentation

open access: yesIEEE Access, 2023
The precise segmentation of the glomerular basement membrane (GBM) can aid pathologists in making accurate pathological diagnoses. However, conventional methods solely focus on segmenting GBM from the background, disregarding the interconnections between

Is EC class predictable from reaction mechanism?

open access: yesBMC Bioinformatics, 2012
Background We investigate the relationships between the EC (Enzyme Commission) class, the associated chemical reaction, and the reaction mechanism by building predictive models using Support Vector Machine (SVM), Random Forest (RF) and k-Nearest ...
