Less-forgetful Learning for Domain Expansion in Deep Neural Networks

no code implementations16 Nov 2017 Heechul Jung, Jeongwoo Ju, Minju Jung, Junmo Kim

Expanding the domain that deep neural network has already learned without accessing old domain data is a challenging task because deep neural networks forget previously learned information when learning new data from a new domain.

Less-forgetting Learning in Deep Neural Networks

no code implementations1 Jul 2016 Heechul Jung, Jeongwoo Ju, Minju Jung, Junmo Kim

Surprisingly, our method is very effective to forget less of the information in the source domain, and we show the effectiveness of our method using several experiments.

Rigid Motion Segmentation using Randomized Voting

no code implementations CVPR 2014 Heechul Jung, Jeongwoo Ju, Junmo Kim

For evaluation of our algorithm, Hopkins 155 dataset, which is a representative test set for rigid motion segmentation, is adopted; it consists of two and three rigid motions.
