On Fitting Finite Dirichlet Mixture Using ECM and MML [chapter]

Nizar Bouguila, Djemel Ziou
2005 Lecture Notes in Computer Science  
Some of the known results are deduced from the results obtained. Numerical results are illustrated for the models under consideration. 2 Pair-copula constructions of multiple dependence.  ...  Fluid queue models play a vital role in the performance analysis of computer and telecommunication networks.  ...  The basic assumptions made on the spiking activity permit us to consider spike trains as realizations of a stochastic point process. Then, it is required to characterize it in a most compact way.  ...

Ping-pong beam training for reciprocal channels with delay spread

Elisabeth de Carvalho, Jorgen Bach Andersen
2015 2015 49th Asilomar Conference on Signals, Systems and Computers  
The proposed detector requires no training signals and outerforms conentional covariance matrix based detectors which require training.  ...  It also explores the connections between D-AMP and Bayesian AMP, which employs a probabilistic model for the signal.  ...  They are trained for only one value of SNR and used to classify the signals from a wide range of SNR.  ...

Sensor Applications for Human Activity Recognition in Smart Environments

Biying Fu
Human activity recognition (HAR) is the automated recognition of individual or group activities from sensor inputs.  ...  However, more stationary exercises, such as strength-based training or stretching are also important for a healthy life-style, as they improve body coordination and balance.  ...  The server has access to the trained CNN model and calculated templates from the training data.  ...

Signal Processing of UWB Radar Signals for Human Detection Behind Walls

Mohamed Hussein Emam Mabrouk Mabrouk, Université D'Ottawa / University Of Ottawa, Université D'Ottawa / University Of Ottawa
Non-contact life detection is a significant component of both civilian and military rescue applications. As a consequence, this interest has resulted in a very active area of research.  ...  Human posture estimation has been performed by measuring the distance of the chest displacements from the ground. This requires multiple UWB receivers and a more complex system.  ...  In [39] , a training set of data has been used in a neural network to classify human postures.  ...
