Ternary and Binary Quantization for Improved Classification

no code implementations31 Mar 2022 Weizhi Lu, Mingrui Chen, Kai Guo, Weiyu Li

Furthermore, this quantization property could be maintained in the random projections of sparse features, if both the features and random projection matrices are sufficiently sparse.

Cascaded Compressed Sensing Networks: A Reversible Architecture for Layerwise Learning

no code implementations20 Oct 2021 Weizhi Lu, Mingrui Chen, Kai Guo, Weiyu Li

In the letter, we show that target propagation could be achieved by modeling the network s each layer with compressed sensing, without the need of auxiliary networks.

Deep Learning to Ternary Hash Codes by Continuation

no code implementations16 Jul 2021 Mingrui Chen, Weiyu Li, Weizhi Lu

Recently, it has been observed that {0, 1,-1}-ternary codes which are simply generated from deep features by hard thresholding, tend to outperform {-1, 1}-binary codes in image retrieval.

Learning Actions from Human Demonstration Video for Robotic Manipulation

no code implementations10 Sep 2019 Shuo Yang, Wei zhang, Weizhi Lu, Hesheng Wang, Yibin Li

However, the general video captioning methods focus more on the understanding of the full frame, lacking of consideration on the specific object of interests in robotic manipulations.

Sparse Matrix-based Random Projection for Classification

no code implementations12 Dec 2013 Weizhi Lu, Weiyu Li, Kidiyo Kpalma, Joseph Ronsin

As a typical dimensionality reduction technique, random projection can be simply implemented with linear projection, while maintaining the pairwise distances of high-dimensional data with high probability.
