Team Participating in the NSF Kick-off Meeting

All team participants attend the 2-day virtual meeting hosted by NSF's EPSCoR PDs in part or in full. They met cognizant NSF directors, learnt project reporting and evaluation expectations, and were informed budgetary issues. Short presentations by all funded T2 projects permitted our team members to know the scopes of all other projects for possible future collaboration. Programmatic experience shared by PIs from earlier years' funded T2 projects offered valuable guidance for our project going forward. Details about team management, governance, coordination, and possible conflict/problem resolution were also clarified during the 2nd day's breakout session. The team initiated the development of a strategic and milestone plan as well in the 2nd meeting day.

PREFER Team 2nd Meeting

Most team participants joined this virtual meeting to sort out details about workforce development regarding undergraduate engagement and summer research support. The meeting also updated team members with data output gathering service for all project activities and inform about the NSF's project kick-off meeting to take place in the following week.

Team Member Technical Presentation

A presentation, entitled "The Future of Weather Forecasting," was given by Eric Rappin at the Commonwealth Computing Summit at the University of Kentucky on 13 Oct. 2020, briefly outlining how PREFER is aimed at advancing next-generation forecasts through a set of simple machine learning models (dubbed 1-D modelets). It discussed the initial PREFER approach on training ML models to correlate meteorological quantities based on years of Kentucky Mesonet observations (e.g., how does wind direction impact humidity). Further investigation would be on developing 2-D modelets to account for spatial correlations.

Investigator, Dr. Hassan Najafi, was invited to give a talk at the ECE Department Fall 2020 Colloquium (Eleanore Hale Wilson Lecture Series), University of Minnesota-Twin Cities, on his cutting-edge solution for energy-efficient design of near-sensor stochastic computing circuits. The presentation on "Time-based Stochastic Processing for Near-Sensor AI" was made virtually via Zoom with more than 60 attendees, including faculties, graduate and undergraduate students, followed by a 25 minute Q&A and discussions at the end.

PREFER Team Kick-off Meeting

All 14 team participants joined the meeting via Zoom for 1.5 hours to review technical tasks under the funded project, to affirm their respective task involvement, and finalize the team execution strategy that contains the activity level, the task level, the whole team level. Each task has one lead, who is responsible for assigning and coordinating research activities included in the task. A task-level meeting is expected to hold monthly or as needed, whereas a team-level meeting is expected three times annually.
