Analysis Dictionary Learning Based Classification: Structure for Robustness

IEEE Transactions on Image Processing, 28(12), 6035–6046.

By: W. Tang n, A. Panahi n, H. Krim n  & L. Dai*

author keywords: Discriminate analysis dictionary learning; distributed analysis dictionary learning; structured mapping; supervised learning
topics (OpenAlex): Remote-Sensing Image Classification; Image Processing Techniques and Applications; Sparse and Compressive Sensing Techniques; Face and Expression Recognition; Advanced Image and Video Retrieval Techniques; Domain Adaptation and Few-Shot Learning
TL;DR: A consensus structured analysis dictionary and a global classifier are jointly learned in the distributed approach to safeguard the discriminative power and the efficiency of classification. (via Semantic Scholar)

Community Detection and Improved Detectability in Multiplex Networks

Huang, Y., Panahi, A., Krim, H., & Dai, L. (2019, October 23). IEEE Transactions on Network Science and Engineering, Vol. 7, pp. 1697–1709.

By: Y. Huang n, A. Panahi*, H. Krim n  & L. Dai*

author keywords: Multiplexing; Stochastic processes; Belief propagation; Correlation; Periodic structures; Computational modeling; Bayes methods; Network theory (graphs); graphical models; belief propagation
topics (OpenAlex): Complex Network Analysis Techniques; Opinion Dynamics and Social Influence; Data Visualization and Analytics; Advanced Graph Neural Networks; Bayesian Modeling and Causal Inference
TL;DR: A generative model that leverages the multiplicity of a single community in multiple layers, with no prior assumption on the relation of communities among different layers is proposed, which shows a better detection performance over a certain correlation and signal to noise ratio (SNR) range.

Deep Dictionary Learning: A PARametric NETwork Approach

Mahdizadehaghdam, S., Panahi, A., Krim, H., & Dai, L. (2019, May 8). IEEE Transactions on Image Processing, Vol. 28, pp. 4790–4802.

By: S. Mahdizadehaghdam n, A. Panahi n, H. Krim n  & L. Dai*

author keywords: Image classification; deep learning; sparse representation
topics (OpenAlex): Image Processing Techniques and Applications; Image and Signal Denoising Methods; Digital Media Forensic Detection; Generative Adversarial Networks and Image Synthesis; Sparse and Compressive Sensing Techniques
TL;DR: The performance of the proposed hierarchical method increases by adding more layers, which consequently makes this model easier to tune and adapt and shows a remarkably lower fooling rate in the presence of adversarial perturbation. (via Semantic Scholar)

Pansharpening via coupled triple factorization dictionary learning

Skau, E., Wohlberg, B., Krim, H., & Dai, L. (2016, March 1). International Conference on Acoustics Speech and Signal Processing, pp. 1234–1237.

By: E. Skau n, B. Wohlberg *, H. Krim n  & L. Dai n

topics (OpenAlex): Advanced Image Fusion Techniques; Photoacoustic and Ultrasonic Imaging; Image Enhancement Techniques
TL;DR: The results demonstrate that the data fusion model can successfully be applied to the pan-sharpening problem and is applicable to the pansharpening data fusion problem. (via Semantic Scholar)
