Multi-Task Learning with Incomplete Data for Healthcare

no code implementations6 Jul 2018 Xin J. Hunt, Saba Emrani, Ilknur Kaynar Kabul, Jorge Silva

Multi-task learning is a type of transfer learning that trains multiple tasks simultaneously and leverages the shared information between related tasks to improve the generalization performance.

Effective Connectivity-Based Neural Decoding: A Causal Interaction-Driven Approach

no code implementations24 Jul 2016 Saba Emrani, Hamid Krim

We propose a geometric model-free causality measurebased on multivariate delay embedding that can efficiently detect linear and nonlinear causal interactions between time series with no prior information.
