Efficient Deep Feature Learning and Extraction via StochasticNets [PDF]

open access: yesarXiv, 2015
Deep neural networks are a powerful tool for feature learning and extraction given their ability to model high-level abstractions in highly complex data. One area worth exploring in feature learning and extraction using deep neural networks is efficient neural connectivity formation for faster feature learning and extraction.

Large Margin Multi-modal Multi-task Feature Extraction for Image Classification [PDF]

open access: yesIEEE Transactions on Image Processing (Volume: 25, Issue: 1, Jan. 2016), 2019
The features used in many image analysis-based applications are frequently of very high dimension. Feature extraction offers several advantages in high-dimensional cases, and many recent studies have used multi-task feature extraction approaches, which often outperform single-task feature extraction approaches.
