Machine learning has attracted a lot attention recently. In this talk, I will use several case studies to demonstrate what machine learning can do for Science and Engineering.

It is observed that birds, bats, insects, and fish can routinely harness unsteady fluid phenomena to improve their propulsive efficiency, maximize thrust and lift, and increase maneuverability. In this talk, I will demonstrate how to use machine learning strategy to characterize the time-varying fluid flows with very limited sensor information in modern engineering, for instance, biological propulsion and bio-inspired engineering design.

In addition, I will also present how to use machine learning techniques to employ very limited satellite data or sensor information to improve the climate model predictive capability or identify the contaminant source locations. Particularly, an adaptive importance sampling technique will be introduced to utilize machine learning method to capture multimodal distribution using a mixture of Gaussian distribution.

Ebola disease has been taking thousands of people’s life. It is critical to develop effective strategy to prevent Ebola’s outbreak. I will present how we can use machine learning techniques to develop more accurate Ebola model using limited data. In addition, we employ this accurate Ebola model to develop and test several different strategies to studies its effectiveness in preventing Ebola’s outbreak.
