Compressed Sensing ECG using Restricted Boltzmann Machines

Luisa Polania, Rafael Plaza

Recently, it has been shown that compressed sensing (CS) has the potential to lower energy consumption in wireless electrocardiogram (ECG) systems. By reducing the number of acquir…

Resilience of ranks of higher inclusion matrices

Rafael Plaza, Qing Xiang

Let $n \geq r \geq s \geq 0$ be integers and $F$ a family of $r$ -subsets of $[n]$ . Let $W_{r, s}^{F}$ be the higher inclusion matrix of the subsets in ${\mathcal…

Characterization of intersecting families of maximum size in $P S L (2, q)$

Ling Long, Rafael Plaza, Peter Sin +1

We consider the action of the $2$ -dimensional projective special linear group $P S L (2, q)$ on the projective line $P G (1, q)$ over the finite field $\F_q$, where $q$ is an odd prime po…
