  1. Surviving the Data Deluge: Scalable feature extraction, discrimination and analysis … … Svetha Venkatesh Curtin University, Australia 2 1 2 3 3 NSF Workshop Jan, 2011 with Dinh Phung and Duc Son Pham

  2. SensingBeyond Nyquist, compress at information level sensor sub-sampling temporal sub-sampling

  3. Analysis Machine learning that ‘ubiquitously’ scales … Model complexity grows as data grows. Non Parametric models … 2 1 2 3 3 … data Example: Bayesian nonparametrics

  4. Multi-scale Decision makingEmotion counts! • Expected utility (common) • Immediate emotion and role in decision making • Pervasive Framework for immediate affect detection and its role in decision making • First application area – autism – use/build sensors to regulate affect (mobile phones/ipad) • Later examine decision making regulated by affect anxiety report Immediate emotions Decision/ behaviour Expected emotions Expected consequences Incidental influences
