A Novel Geometric Framework on Gram Matrix Trajectories for Human Behavior Understanding

Anis Kacem, Mohamed Daoudi, Boulbaba Ben Amor +2

In this paper, we propose a novel space-time geometric representation of human landmark configurations and derive tools for comparison and classification. We model the temporal evo…

Robust Covariance Adaptation in Adaptive Importance Sampling

Yousef El-Laham, Victor Elvira, Monica F. Bugallo

Importance sampling (IS) is a Monte Carlo methodology that allows for approximation of a target distribution using weighted samples generated from another proposal distribution. Ad…

Deep Covariance Descriptors for Facial Expression Recognition

Naima Otberdout, Anis Kacem, Mohamed Daoudi +2

In this paper, covariance matrices are exploited to encode the deep convolutional neural networks (DCNN) features for facial expression recognition. The space geometry of the covar…

Accelerating MCMC Algorithms

Christian P. Robert, Victor Elvira, Nick Tawn +1

Markov chain Monte Carlo algorithms are used to simulate from complex statistical distributions by way of a local exploration of these distributions. This local feature avoids heav…

Spatial Field Reconstruction and Sensor Selection in Heterogeneous Sensor Networks with Stochastic Energy Harvesting

Pengfei Zhang, Ido Nevat, Gareth W. Peters +2

We address the two fundamental problems of spatial field reconstruction and sensor selection in het- erogeneous sensor networks. We consider the case where two types of sensors are…
