In this work, we first propose a novel spectral-based subspace clustering algorithm that seeks to represent each point as a sparse convex combination of a few nearby points. We then extend the algorithm to a constrained clustering and active learning framework. Our motivation for developing such ...
In recent years, sparse representation-based classification (SRC) is a growing technique and has been a successful technique on classifying MI-based Electroencephalography (EEG) signals. To further boost the proficiency of SRC technique, in this paper, a weighted SRC (WSRC) has been proposed for...

The sparse representation enabled a full extraction of terrain information from the low-resolution and high-precision 90 m TanDEM-X DEM. The adaptive regularisation variation framework solved the terrain discontinuities (e.g., noise) and preserved topographical features, thus ensuring the fused DEM ...
Then, a joint sparse representation (JSR) classification is used to obtain the representation residuals of different pixels. Finally, the class label of each pixel is determined by the defined decision function that combines the WSCR and JSR. Experimental results obtained on two real HSI datasets ...
The new schemes are shown to outperform the traditional method in the applications, such as component detection, sparse representation for ECG signal and 2-d time series modeling. Besides, experimental results also indicate that subtree based algorithm is with much lower time complexity than tree ...
Sparse representation (not implemented here)HyperLogLog++ object shares the same interface as HyperLogLog. So you can use all the HyperLogLog functions in HyperLogLog++.from datasketch import HyperLogLogPlusPlus # Initialize an HyperLogLog++ object. hpp = HyperLogLogPlusPlus() # Everything else is the...

we propose a new method called weighted block-sparse low rank representation (WBSLRR) which considers the available prior knowledge while learning a low rank data representation, and also develop a simple but effective approach to obtain the clustering result of faces. Moreover, after using several...
