A combined strategy for multivariate density estimation
Alejandro Cholaquidis, Ricardo Fraiman, Badih Ghattas +1
Non-linear aggregation strategies have recently been proposed in response to the problem of how to combine, in a non-linear way, estimators of the regression function (see for inst…
Set Estimation Under Biconvexity Restrictions
Alejandro Cholaquidis, Antonio Cuevas
A set in the Euclidean plane is said to be biconvex if, for some angle , all its sections along straight lines with inclination angles and are convex sets…
On semi-supervised learning
Alejandro Cholaquidis, Ricardo Fraiman, Mariela Sued
Semi-supervised learning deals with the problem of how, if possible, to take advantage of a huge amount of unclassified data, to perform a classification in situations when, typica…
Robust Fusion Methods for Structured Big Data
Catherine Aaron, Alejandro Cholaquidis, Ricardo Fraiman +1
We address one of the important problems in Big Data, namely how to combine estimators from different subsamples by robust fusion procedures, when we are unable to deal with the wh…
