JoAnne Ting
About Me:
I'm currently CEO & President of DataSeer, a Houstonbased startup that applies machine learning + computer vision for digitization of industrial engineering diagrams. Previously, I was Lead Data Scientist at Arundo Analytics from 2018 to 2020, working on industrial ML, and Director of Data Science at Aura Financial from 2014 to 2018, building systems to optimize credit and operational risk. From 2011 to 2013, I was a Research Scientist at Bosch Research and Technology Center in Palo Alto, CA. Prior to that, I spent some time at the University of Edinburgh in 2009, working with Sethu Vijayakumar, and at the University of British Columbia from 2010 to 2011, as an NSERC postdoctoral fellow, working with Nando de Freitas, Kevin Murphy, and Jim Little. I received my PhD in Computer Science from the University of Southern California in 2009, where I was advised by Stefan Schaal, and a BASc in Computer Engineering from the University of Waterloo in 2003.

Variational Bayesian Least Squares:
A variational Bayesian algorithm performs efficient highdimensional linear regression, handling large numbers of irrelevant and redundant dimensions in the input data. Good references include Ting, D'Souza, Vijayakumar & Schaal (2010) in Neural Computation and Ting & al. (Neural Networks: Neuroinformatics, 2008). Older conference proceedings include Ting & al. (2005) in NIPS and D'Souza, Vijayakumar & Schaal (2004) in ICML.

Bayesian Regression with Input Noise for High Dimensional Data:
A Bayesian treatment of factor analysis in jointspace that can accurately identify parameters in a highdimensional linear regression problem when input data is noisecontaminated. An application to nonlinear parameter identification in Rigid Body Dynamics is described in Ting, Mistry, Peters, Schaal & Nakanishi (RSS 2006). A good reference is Ting, D'Souza & Schaal in Neural Networks (2010).

Realtime outlier detection:
A weighted least squareslike approach to outlier detection, where each data sample has a weight associated with it. This model treats the weights probabilistically and learn their optimal values, avoiding modeling with heuristic error functions, sampling or tuning of open parameters (such as a threshold parameter). Details on how to perform automatic outlier detection in linear regression can be found in the paper by Ting, D'Souza & Schaal (2007) in the ICRA proceedings. We can also incorporate this approach to a Kalman filter, allowing us to do realtime automatic outlier detection on streaming data. A good reference is Ting, Theodorou & Schaal (2007) in ECML.
