EdgeConvFormer: Dynamic Graph CNN and Transformer based Anomaly Detection in Multivariate Time Series

no code implementations4 Dec 2023 Jie Liu, Qilin Li, Senjian An, Bradley Ezard, Ling Li

Transformer-based models for anomaly detection in multivariate time series can benefit from the self-attention mechanism due to its advantage in modeling long-term dependencies.

Semi-supervised Learning on Graph with an Alternating Diffusion Process

no code implementations16 Feb 2019 Qilin Li, Senjian An, Ling Li, Wanquan Liu

Graph-based semi-supervised learning usually involves two separate stages, constructing an affinity graph and then propagating labels for transductive inference on the graph.

Exploiting Layerwise Convexity of Rectifier Networks with Sign Constrained Weights

no code implementations14 Nov 2017 Senjian An, Farid Boussaid, Mohammed Bennamoun, Ferdous Sohel

By introducing sign constraints on the weights, this paper proposes sign constrained rectifier networks (SCRNs), whose training can be solved efficiently by the well known majorization-minimization (MM) algorithms.

On the Compressive Power of Deep Rectifier Networks for High Resolution Representation of Class Boundaries

no code implementations24 Aug 2017 Senjian An, Mohammed Bennamoun, Farid Boussaid

To show the superior compressive power of deep rectifier networks over shallow rectifier networks, we prove that the maximum boundary resolution of a single hidden layer rectifier network classifier grows exponentially with the number of units when this number is smaller than the dimension of the patterns.

From Deep to Shallow: Transformations of Deep Rectifier Networks

no code implementations30 Mar 2017 Senjian An, Farid Boussaid, Mohammed Bennamoun, Jiankun Hu

Similarly, for a residual net and a conventional rectifier net with the same structure except for the skip connections in the residual net, the corresponding single hidden layer representation of the residual net is much more complex than the corresponding single hidden layer representation of the conventional net.

ResFeats: Residual Network Based Features for Image Classification

no code implementations21 Nov 2016 Ammar Mahmood, Mohammed Bennamoun, Senjian An, Ferdous Sohel

Deep residual networks have recently emerged as the state-of-the-art architecture in image segmentation and object detection.

Leveraging Structural Context Models and Ranking Score Fusion for Human Interaction Prediction

no code implementations18 Aug 2016 Qiuhong Ke, Mohammed Bennamoun, Senjian An, Farid Bossaid, Ferdous Sohel

The structural models, including the spatial and the temporal models, are learned with Long Short Term Memory (LSTM) networks to capture the dependency of the global and local contexts of each RGB frame and each optical flow image, respectively.

Contractive Rectifier Networks for Nonlinear Maximum Margin Classification

no code implementations ICCV 2015 Senjian An, Munawar Hayat, Salman H. Khan, Mohammed Bennamoun, Farid Boussaid, Ferdous Sohel

The contractive constraints ensure that the achieved separating margin in the input space is larger than or equal to the separating margin in the output layer.
