Delta-Dual Hierarchical Dirichlet Processes: A pragmatic abnormal behaviour detector
In the security domain a key problem is identifying rare behaviours of interest. Training examples for these behaviours may or may not exist, and if they do exist there will be fe...

Visual saliency for automatic target detection, boundary detection, and image quality assessment
We present a visual saliency detection method and its applications. The proposed method does not require prior knowledge (learning) or any pre-processing step. Local visual descri...

The role of synaptic facilitation in spike coincidence detection
Using a realistic model of activity dependent dynamical synapse, which includes both depressing and facilitating mechanisms, we study the conditions in which a postsynaptic neuron...

A Post-Detection SNR-Aided Timing Recovery Loop for MIMO-OFDM Receivers
--- In this paper, a novel third-order Phase Lock Loop (PLL) is proposed for the timing recovery in MIMO-OFDM systems. It differentiates from conventional timing recovery algorithm...

The early bird gets the buzz: detecting anomalies and emerging trends in information networks
In this work we propose a novel approach to anomaly detection in streaming communication data. We first build a stochastic model for the system based on temporal communication pa...
