Structure Optimization for Deep Multimodal Fusion Networks using Graph-Induced Kernels

no code implementations3 Jul 2017 Dhanesh Ramachandram, Michal Lisicki, Timothy J. Shields, Mohamed R. Amer, Graham W. Taylor

A popular testbed for deep learning has been multimodal recognition of human activity or gesture involving diverse inputs such as video, audio, skeletal pose and depth images.

Activity Recognition

Action-Affect Classification and Morphing using Multi-Task Representation Learning

no code implementations21 Mar 2016 Timothy J. Shields, Mohamed R. Amer, Max Ehrlich, Amir Tamrakar

We propose a new model that enhances the CRBM model with a factored multi-task component to become Multi-Task Conditional Restricted Boltzmann Machines (MTCRBMs).

Human Social Interaction Modeling Using Temporal Deep Networks

no code implementations6 May 2015 Mohamed R. Amer, Behjat Siddiquie, Amir Tamrakar, David A. Salter, Brian Lande, Darius Mehri, Ajay Divakaran

We present a novel approach to computational modeling of social interactions based on modeling of essential social interaction predicates (ESIPs) such as joint attention and entrainment.
