ACEMS Public Lecture on "Improving" Prediction

On August 27, I will deliver an ACEMS Public Lecture on "Improving" Prediction of Human Behavior Using Behavior Modification. Note the quotes around "Improving"!

Professor Rob Hyndman from Monash University is the host, and will moderate the Q&A session following my virtual talk. I plan to make the talk accessible to the wide public while introducing critical statistical and machine learning concepts/tools.

Lecture recording:


Note: I was planned to deliver the public talk in February in Melbourne, but due to COVID19 I was unable to travel to Australia. The upcoming talk is on new work, and is my first public talk on this topic.

ACEMS is the Australian Research Council Centre for Excellent for Mathematical and Statistical Frontiers.

Elected as IMS Fellow

From today's press release (announcement on the IMS website and IMS bulletin):

Galit Shmueli, Tsing Hua Distinguished Professor, National Tsing Hua University, has been named Fellow of the Institute of Mathematical Statistics (IMS). Dr. Shmueli received the award for extraordinary contributions to statistical methods for biosurveillance, online commerce, and information quality, and for outstanding dissemination of statistical ideas through journal and textbook publications.

Each Fellow nominee is assessed by a committee of their peers for the award. In 2020, after reviewing 73 nominations, 35 were selected for Fellowship. Created in 1935, the Institute of Mathematical Statistics is a member organization that fosters the development and dissemination of the theory and applications of statistics and probability. The IMS has 3,500 active members throughout the world. Approximately 12% of the current IMS membership has earned the status of fellowship. 

I thank my nominator and letter writers!

New COM-Poisson paper pubished at JCGS

Our paper A Tree-Based Semi-Varying Coefficient Model for the COM-Poisson Distribution" is now published online at the Journal of Computational & Graphical Statistics. This was part of Suneel Chatla's PhD dissertation at NTHU (he is now faculty at UT El Paso).

In the paper, we propose a tree-based semi-varying coefficient model for the Conway–Maxwell–Poisson (CMP) distribution. The advantage of tree-based methods is their scalability to high-dimensional data. We develop CMPMOB, an estimation procedure for a semi-varying coefficient model, using model-based recursive partitioning (MOB). The proposed framework is broader than the existing MOB framework as it allows node-invariant effects to be included in the model. To simplify the computational burden of the exhaustive search employed in the original MOB algorithm, a new split point estimation procedure is proposed by borrowing tools from change point estimation methodology. The proposed method uses only the estimated score functions without fitting models for each split point and, therefore, is computationally simpler. Since the tree-based methods only provide a piece-wise constant approximation to the underlying smooth function, we further propose the CMPBoost semi-varying coefficient model which uses the gradient boosting procedure for estimation. The usefulness of the proposed methods are illustrated using simulation studies and a real example from a bike sharing system in Washington, DC.
