ICML 2013 Paper Acceptance: Efficient Lifelong Learning
Posted December 6, 2012
Paul and I just had a paper accepted to ICML 2013 on an efficient method for online multi-task learning in a lifelong learning setting. Our approach, known as ELLA, shows equivalent performance to batch multi-task learning methods with over a 1,000x speedup in learning all tasks. Most importantly, the computational complexity of the approach is independent of the number of tasks learned, enabling us to learn an individual new task with over 38,000x speedup.
