• #### Inner ideals of real Lie algebras ﻿

(2022-01-17)
If $L$ is a Lie algebra, a subspace $B$ of $L$ is called an \emph{inner ideal} if $[B,[B,L]]\subset B$. This notion is inspired in Jordan algebras and it dues to [1], which used it to reconstruct the geometry defined by ...
• #### Time Series Clustering with Deep Reservoir Computing ﻿

(Springer, 2020)
This paper proposes a method for clustering of time series, based upon the ability of deep Reservoir Computing networks to grasp the dynamical structure of the series that is presented as input. A standard clustering ...
