- Computer ScienceInternational Conference on Machine Learning
- 1 June 2018
A novel hybrid norm is designed as the minimization objective to enforce the superposition of two weighted sparsity constraints, one on the shared interactions and the other on the task-specific structural patterns, which enables JEEK to elegantly consider various forms of existing knowledge based on the domain at hand and avoid the need to design knowledge-specific optimization.
