SSA Canberra Branch Meetings

A (tentative) schedule for SSA Canberra meetings in 2020 can be found here

UPDATE:

Although there are only three meetings left to close out the intended schedule of branch events in 2020 (please see the top of https://statsoc.org.au/Canberra-Branch-meetings), to offer some certainty for the remainder of this year the SSA Canberra council has decided that these three events will all be held online (most likely via Zoom), as has been the case for the past several branch meetings. 

While the situation in the ACT has been rather fortunate with respect to COVID19 (and let us hope it remains that way!), we and the SSA as a whole have adopted a "better safe than sorry" approach, and do not wish to put our members/attendees at risk or in an awkward position of having to choose whether to risk attending physical meetings or not. We understand that this decision means the monthly SSA meet up in person with friends and colleagues to catch up over a talk and/or dinner, which many of us sorely miss, won't be taking place for some time yet. However, we hope you understand our decision, and can bear with the "online wine and cheese" for a while longer as we work through the current challenges together 

As a heads up, the branch meetings to round out this year are:

  1. Tuesday October 27 early evening: Winner of the Dennis Trewin prize 2020
  2. Tuesday November 24 around lunchtime (Knibbs lecture): Ray Carroll, Texas A&M University (Celebrating Alan Welsh's 60th birthday and his contributions to statistics). 

In early 2021, we will reevaluate the situation given what information is available then and go from there. If you have any questions and comments, please feel free to contact us at ssacanberra@gmail.com

NEXT BRANCH MEETING

Please see below for details of the next branch meeting, where we are proud to have the winner of the 2020 Dennis Trewin prize present on their research! Please note registration is required beforehand. Please also forward the below to whoever you think may be interested.

Date: Tuesday 27 October

Time: 6pm - 7pm AEST [the Zoom meeting will be open from around 5:30pm if people wish to mingle 🗨]


RSVP: Please register in advance for this meeting at

Topic: Bayesian Modelling of Non-Linear Sensor Arrays.

Speakers:
Basim S.O. Alsaedi, formerly University of New England.

Abstract:

Non-linear multivariate calibration methods are increasingly used to extract information from different types of sensors. As the complexity of the data increases, new methods are required to estimate parameters and to provide realistic estimates of uncertainty. This talk is focused on the study of establishing a meaningful limit of detection for sensors and sensor arrays with non-linear response.  We propose a new limit of detection (LOD) definition for ion selective electrodes for sensors and sensor arrays. The Bayesian infostructure is used to calculate the uncertainty associated with the estimates. Furthermore, a comprehensive study of modularisation in sensors and sensor arrays is conducted, motivated by practical limitations of the “cut” function in Bayesian graphical models as implemented by BUGS. Alternative algorithms, based on Approximate Bayesian computation (ABC), for sensors and sensor arrays are also proposed and evaluated.


Biography:

Dr Alsaedi recently graduated with a PhD in statistics from the School of Science and Technology at the University of New England. His PhD thesis was devoted to the study of non-linear multivariate Bayesian calibration i.e. Bayesian modelling for newly developed chemical sensors and sensor arrays. He is currently a lecturer in the department of statistics at the University of Tabuk, Saudi Arabia.
