DOI: 10.1002/sim.9367
Abstract: It is challenging to evaluate the genetic impacts on a biologic feature and separate them from environmental impacts. This is usually achieved through twin studies by assessing the collective genetic impact defined by the differential… read more here.

DOI: 10.1016/j.frl.2018.04.006
Abstract: Abstract We evaluate a utility indifference price with an exponential utility function, which we call a risk-sensitive value measure, under a normal mixture distribution with time-varying volatility. We compare the risk-sensitive value measure and mean-variance… read more here.

DOI: 10.1109/tac.2020.2995674
Abstract: In this article, a new variational adaptive Kalman filter with Gaussian-inverse-Wishart mixture distribution is proposed for a class of linear systems with both partially unknown state and measurement noise covariance matrices. The state transition and… read more here.

DOI: 10.1109/tcds.2021.3075280
Abstract: Few-shot learning aims at heuristically resolving new tasks with limited labeled data; most of the existing approaches are affected by knowledge learned from similar experiences. However, inter-class barriers and new samples insufficiency limit the transfer… read more here.
